What about APCC Pro/APPM that comes included with the purchase of a mount, such as the Mach2?. I don't see anything mentioned about it in the FAQ.
 
 
Thanks,

APCC v1.9 is now available for download at the following links and from the APCC Download Center of our website.

https://www.apastrosoftware.com/apcc_download/ApccStandardLatest.exe
https://www.apastrosoftware.com/apcc_download/ApccProLatest.exe


This version has several long-awaited and significant new features for APCC Pro:

  •          APCC Pro - Declination-Arc tracking algorithm. This new algorithm is an alternative to the normal all sky tracking model that APCC Pro uses.
  •          APCC Pro - APPM can use ASTAP for plate-solving.
  •          APCC Pro - APPM can use NINA for camera control.
  •          APCC Pro - For third-party satellite trackers, real-time RA/Dec can be returned using the :GRGD# command.

Complete Version History with all updates and bug fixes for APCC Standard and PRO versions:

https://www.astro-physics.info/tech_support/software/apcc/apcc-version-history.pdf


Many thanks to Dale Ghent and Ray Gralak for working together to add NINA camera control to APCC. We know that many APCC users have been very interested in NINA to improve their workflow.

 

Since the introduction of APCC years ago, our website has stated that we intended to offer a subscription renewal option after the first year for approximately 20% of the price.  Many of you have been using APCC for years without any extra charge as we added new features and refined our pointing model.  Many features were suggested by users to streamline their workflow, provide additional information or control, integrate with other complimentary software and to safeguard your system.


The time has now come for us to implement our subscription renewal program so that we can continue to develop new features that our users have requested.


If the date of your APCC license key is August 1, 2020 or later, all of the new features outlined in the version history will be activated when you install v1.9.


If the date of your APCC license key is earlier than August 1, 2020, only the bug fixes and minor updates will be activated. To activate all the new major features, you will need to purchase a one-year renewal subscription. When that process is complete, you will receive a new license that includes the renewal date.


Major points:

  •         Renewal is optional. Your current version of APCC will continue to operate as it always has.
  •         Everyone is entitled to the bug fixes and minor updates of v1.9 and all new versions going forward regardless of whether you renew your subscription or not. We encourage you to keep your software up-to-date.
  •         The process for obtaining the one-year subscription takes you to the DigitalRiver MyCommerce e-commerce website. It is available to you at your convenience and does not require contact with our office.

You probably have many questions about this new process. We have anticipated many of these and encourage you to visit the Order and FAQ tabs of the APCC page on our website. Please take a few moments to read that first before your posting questions here.

Re: Ugghhh cross threaded CW shaft into CW shaft adapter with metal threaded sleeve

Don Anderson
 

Good articles on galling Cytan. Thread galling is a potential problem with any metal threaded joint but is particularly problematic with SS due the the properties of this SS.
If I had to guess, it is likely you had some contamination in the threads possibly a metal shaving which caused damage to the threads. Once you tried to back it out, the threads became galled. Another possibility is when you last 
installed the shaft that the flat faced surfaces were not fully mated; if they weren't, and there was a gap, it is possible the counter weights pulling down on the pin of the shaft damaged the threads on the the shaft or adapter or both.

I thing the take away on all of this is to insure that the threads (shaft and adapter) are scrupulously clean. I would apply a little anti seize compound and only make up the joint hand tight. Make sure the two flat faced surfaces on
the shaft and adapter are fully mated with a fibre washer in between. 
Just some ideas.

Hi Rolando,

This thing about using brass could be an old wive's tale that I thought I had heard it about because SS on SS is always prone to galling. Let me talk to the mech. eng. that I work with to see what they think.

It's definitely possible that it is dirt that caused the seizure, but it could easily be the SS on SS galling problem.

Just out of curiosity, do you use any type of grease or anti-seize on the threads of the CW shaft?

In talking with our machinists here, they don't think that using different materials will prevent this. It appears some contaminant was present on the threads which then locked up the shaft inside the adapter. Putting graphite on the threads may have attracted or held a bit of metal or other contaminant.

If it doesn't thread in easily, don't force it. Unscrew it before it galls the metal and clean out whatever is causing it to not thread in.

Re: APCC v1.9 and one-year renewal subscriptions #APCC

ap@CaptivePhotons.com
 

Thank you.  W Hilmo will obviously need to speak for themself, but to me this takes all the sting out of “subscription” models. 

 

It’s more like an (optional) recurring maintenance fee that allows you perpetual rights to the upgrades that come out in that time frame.   

 

Personally I find nothing objectionable to that model.  Free is better, but free is unsustainable.  I certainly want you sustained.

 

Thanks for clarifying.

Hello Linwood,

 

Using your example below, at the end of the year, lacking renewal, all 1.9 features will continue to work forever.  If 1.10 comes out after your 1-year boundary (which is different for each person), those features will not be activated without renewal. 

 

Bug fixes and minor updates are available to everyone, all the time.

Or lacking renewal, you just don’t get 1.10 features if it comes out after the year boundary.

 

To me it’s a subscription only if 1.9 features stop working.  Otherwise it is sort of a prepaid support/upgrade agreement.

 

The flavor of the words in the FAQ imply it is the latter, which is not the kind of subscription model most people object to, where things just stop working.

Re: APCC v1.9 and one-year renewal subscriptions #APCC

You can continue to use the version that you have forever, without a subscription. All the new features that we developed took a lot of people a lot of effort over the last 2 years. As the state of the art of astronomical imaging advances, we are advancing with it. And it isn't cheap or easy keeping up with you guys. APCC Pro is now incredibly powerful and accurate, just ask George who spent 3 days last week imaging until dawn without ever turning on his guiding software. (hey George, when are you going to process those images?).

I've spent most clear nights this year working with both our 1600 and our Mach2 mounts doing imaging-testing with various scopes, and these new functions work great. Ray has worked tirelessly on developing this program and Marj and others have spent all their spare time bringing it all together. When i mean all their spare time, I mean that Marj worked all thru our vacation, and every day including Saturdays and Sundays for the last 2 years.

This is a difficult response for me to write.

I've been eagerly waiting for some of the new features that are included in this release.  But I'm incredibly disappointed with the change to the business model.

Please understand that this has nothing whatsoever to do with cost.  If you put all that great work into new features, and then called it APCC Pro v2, and set a $200 upgrade cost for the major version change, I would have already purchased it by now.  I absolutely support the fact that the folks that write software should be compensated.  I, myself, have made a very good living writing software.  It's allowed me to own your fine products and to retire while I am young enough to enjoy the freedom.  As such, I am familiar with the economics of software development more than most.

My problem is that I am *very* strongly opposed to any subscription model for software that runs local to my machine.  Note that this is different than paying a subscription cost, say, for content as with a streaming service.  My feelings on this are strong enough, that there are other astronomy software packages that I will never be able to use because I will not support the model.  There are even products from the company that I used to work for, that I will never use for this reason.

Until today, I have had nothing but good feelings about all of my interactions with Astro-Physics and your products.  Now, every time that I run APCC Pro, I'm going to be reminded of this subscription model.

I am very sorry to send this response, but I have enough respect for Astro-Physics that I feel that I should make my feelings known, as it affects my position as a customer.  I do not have any expectation that you will change your model over my feedback, but I needed to get it out there.

Many moons ago when I was learning machining under the tutelage of a master gunsmith, I learned that all stainless steel and aluminum formulas, at the microscopic level, actually "tear" instead of smoothly cut when machined. This tearing leaves a microscopic feathered surface that can catch and "cold-weld" with other machined aluminum or stainless steel surfaces when they are pulled across each other under pressure. For many years, this characteristic of stainless and aluminum prevented them from being used in many applications and especially in firearms. Sturm Ruger eventually developed a proprietary process of casting stainless in such a way that the cast parts didn't have a feathered surface and could be cast within .001" accuracy. This allowed stainless parts to be put in mechanisms where they would be sliding back and forth or around other stainless parts, without galling or cold-welding. 

Aluminum is a bit different. Because it is softer, springier and has a lower melting point, it can gall in more situations than stainless steel.

I also learned that careful polishing of machined stainless or aluminum parts that knocked down the feathered surface considerably decrease galling. But not prevent it 100%.

Also that using two different stainless formulas with different feathering characteristics on mating parts could help a bit.

Also that machining at angles that didn't result in feathers squarely facing each other helped. But that's just about impossible to do in thread cutting.

About the best thing I found was coating/impregnating the polished or unpolished stainless/aluminum surfaces with Teflon. And if you can't do that, use a Teflon-based lubricant between the two searing surfaces. My favorite Teflon lubricant is Break-Free CLP. One or more drops at the point where the two threads first meet does an amazing job of minimizing galling.

One usually-effective way of preventing stainless steel and/or aluminum threads from galling is to machine them with a tiny bit of extra clearance so they don't ever have enough pressure between them to allow the feathered surfaces to cold-weld to each other. However this approach fails in threaded parts if there ends up being any contamination in the threads, such as aluminum slivers from the last threaded aluminum hole. And I think this is exactly what happened to this particular counterweight shaft and adapter.

How to prevent galling (cold-welding) of AP stainless counterweight shafts and stainless threaded collars? My suggestion would be to carefully inspect and clean the threads of your counterweight shaft with stainless steel brush (fiber or brass brush would be too soft) to make sure there is no contamination or slivers of aluminum left over from the damaged aluminum threaded hole of the old counterweight shaft adapter. Then I would add a couple drops of Break-Free CLP or some other Teflon- based lubricant to the threads before putting them together.

And it is possible to have a sliver of aluminum cold-welded into the thread grooves on your counterweight shaft. If you see that with your 2.5+ reading glasses or magnifying loupe, I would use an Xacto-knife to cut and work it out of the stainless threads before screwing your counterweight shaft into the new stainless adapter. A threading die (1.125x14?) would be the best way to quickly and easily remove the aluminum contamination from the threads, if you had one.

I hope this helps.

Re: APCC v1.9 and one-year renewal subscriptions #APCC

Linwood,

It's even better than what you wrote. :-)

Yes, the v1.9 features will continue to work even if you do not continue to subscribe. Also, even if you don't purchase a subscription, you can still install and run 1.9 and future 1.x versions and you'll get any bug fixes in those versions.

So, the only thing you are actually paying for is any new v1.9 features and also new features introduced up to a year later after the purchase date.

I hope this makes sense?

Also that machining at angles that didn't result in feathers squarely facing each other helped. But that's just about impossible to do in thread cutting.

About the best thing I found was coating/impregnating the polished or unpolished stainless/aluminum surfaces with Teflon. And if you can't do that, use a Teflon-based lubricant between the two searing surfaces. My favorite Teflon lubricant is Break-Free CLP. One or more drops at the point where the two threads first meet does an amazing job of minimizing galling.

One usually-effective way of preventing stainless steel and/or aluminum threads from galling is to machine them with a tiny bit of extra clearance so they don't ever have enough pressure between them to allow the feathered surfaces to cold-weld to each other. However this approach fails in threaded parts if there ends up being any contamination in the threads, such as aluminum slivers from the last threaded aluminum hole. And I think this is exactly what happened to this particular counterweight shaft and adapter.

How to prevent galling (cold-welding) of AP stainless counterweight shafts and stainless threaded collars? My suggestion would be to carefully inspect and clean the threads of your counterweight shaft with stainless steel brush (fiber or brass brush would be too soft) to make sure there is no contamination or slivers of aluminum left over from the damaged aluminum threaded hole of the old counterweight shaft adapter. Then I would add a couple drops of Break-Free CLP or some other Teflon- based lubricant to the threads before putting them together.

And it is possible to have a sliver of aluminum cold-welded into the thread grooves on your counterweight shaft. If you see that with your 2.5+ reading glasses or magnifying loupe, I would use an Xacto-knife to cut and work it out of the stainless threads before screwing your counterweight shaft into the new stainless adapter. A threading die (1.125x14?) would be the best way to quickly and easily remove the aluminum contamination from the threads, if you had one.

I hope this helps.

Re: APCC v1.9 and one-year renewal subscriptions #APCC

W Hilmo
 

This is a difficult response for me to write.

I've been eagerly waiting for some of the new features that are included in this release.  But I'm incredibly disappointed with the change to the business model.

Please understand that this has nothing whatsoever to do with cost.  If you put all that great work into new features, and then called it APCC Pro v2, and set a $200 upgrade cost for the major version change, I would have already purchased it by now.  I absolutely support the fact that the folks that write software should be compensated.  I, myself, have made a very good living writing software.  It's allowed me to own your fine products and to retire while I am young enough to enjoy the freedom.  As such, I am familiar with the economics of software development more than most.

My problem is that I am *very* strongly opposed to any subscription model for software that runs local to my machine.  Note that this is different than paying a subscription cost, say, for content as with a streaming service.  My feelings on this are strong enough, that there are other astronomy software packages that I will never be able to use because I will not support the model.  There are even products from the company that I used to work for, that I will never use for this reason.

Until today, I have had nothing but good feelings about all of my interactions with Astro-Physics and your products.  Now, every time that I run APCC Pro, I'm going to be reminded of this subscription model.

I am very sorry to send this response, but I have enough respect for Astro-Physics that I feel that I should make my feelings known, as it affects my position as a customer.  I do not have any expectation that you will change your model over my feedback, but I needed to get it out there.

Thanks for listening,

This version has several long-awaited and significant new features for APCC Pro:

  •          APCC Pro - Declination-Arc tracking algorithm. This new algorithm is an alternative to the normal all sky tracking model that APCC Pro uses.
  •          APCC Pro - APPM can use ASTAP for plate-solving.

Many thanks to Dale Ghent and Ray Gralak for working together to add NINA camera control to APCC. We know that many APCC users have been very interested in NINA to improve their workflow.

 

Since the introduction of APCC years ago, our website has stated that we intended to offer a subscription renewal option after the first year for approximately 20% of the price.  Many of you have been using APCC for years without any extra charge as we added new features and refined our pointing model.  Many features were suggested by users to streamline their workflow, provide additional information or control, integrate with other complimentary software and to safeguard your system.


The time has now come for us to implement our subscription renewal program so that we can continue to develop new features that our users have requested.


If the date of your APCC license key is August 1, 2020 or later, all of the new features outlined in the version history will be activated when you install v1.9.


If the date of your APCC license key is earlier than August 1, 2020, only the bug fixes and minor updates will be activated. To activate all the new major features, you will need to purchase a one-year renewal subscription. When that process is complete, you will receive a new license that includes the renewal date.


Major points:

  •         Renewal is optional. Your current version of APCC will continue to operate as it always has.
  •         Everyone is entitled to the bug fixes and minor updates of v1.9 and all new versions going forward regardless of whether you renew your subscription or not. We encourage you to keep your software up-to-date.
  •         The process for obtaining the one-year subscription takes you to the DigitalRiver MyCommerce e-commerce website. It is available to you at your convenience and does not require contact with our office.

You probably have many questions about this new process. We have anticipated many of these and encourage you to visit the Order and FAQ tabs of the APCC page on our website. Please take a few moments to read that first before your posting questions here.

[FAQ] Using NINA with Astro-Physics mounts

Dale Ghent
 

Hi folks, I see Marj has announced APCC 1.9 and the new features it brings.

I've prepared a FAQ for users of NINA and Astro-Physics mounts + APCC. It focuses on NINA 1.11 and the plugins and features available in it that AP mount+APCC users can use to take full advantage of those resources. It's an organic document, so I expect revisions and additions to be made over time as both APCC and NINA evolve in their own ways.

Re: Ugghhh cross threaded CW shaft into CW shaft adapter with metal threaded sleeve

Rolando,

 

The head of the machine shop for the utility that I worked for always suggested on applying Never-Seez anti-seize compounds on stainless steel fasteners.  I learned the hard way, when a few of the stainless steel machine screws on my old observatory had seized up and gave me great difficulty when I went to disassemble the dome to install its replacement.

 

Yours truly,

Hi Rolando,
   Believe me, I stopped once I felt it got stuck. I know enough to know when to stop :) But I guess, I wasn't fast enough ..,

   Do you think that a brass insert might actually be better rather than SS? The brass insert will just be a perishable that needs to be replaced once every few years.

If it doesn't thread in easily, don't force it. Unscrew it before it galls the metal and clean out whatever is causing it to not thread in.

I owe the guys doughnuts :)

I'll have to ask a real machinist to do this and that'll cost me lunch :) 

I have to get a new CW adapter anyways, so it's more cost effective to buy both directly from AP.

The more important question, is how to not do this again.

Suggestions?

You still have a perfectly good counterweight shaft if the machineshop cuts new thread on it, it will only be some inches shorter.

P.S. I'll be ordering a new CW shaft + adapter today ...

I thought I had heard it about because SS on SS is always prone to galling
I have never experienced that. SS is quite hard and does not gall in my experience.

Hi Rolando,

This thing about using brass could be an old wive's tale that I thought I had heard it about because SS on SS is always prone to galling. Let me talk to the mech. eng. that I work with to see what they think.

It's definitely possible that it is dirt that caused the seizure, but it could easily be the SS on SS galling problem.

Just out of curiosity, do you use any type of grease or anti-seize on the threads of the CW shaft?

In talking with our machinists here, they don't think that using different materials will prevent this. It appears some contaminant was present on the threads which then locked up the shaft inside the adapter. Putting graphite on the threads may have attracted or held a bit of metal or other contaminant.
