I think continued ASCOM support is essential. My vote is for ASCOM Alpaca. 

Thanks for asking!

Hello all,

Of those users wishing for a non-Windows support for your mount, which platform would you prefer Astro-Physics to devote resources?

INDI or ASCOM Alpaca?

INDI has been around for some time and runs on LINUX and MAC OSX and Windows. ASCOM Alpaca is still in the early stages of development. There are no significant applications that work on LINUX or MACs, and there may not be for some time.

However, ASCOM Alpaca is modular as opposed to INDI's monolithic design. Once drivers are available Alpaca devices can be standalone (over the network or wifi) or on another computer. I believe INDI only works on the computer it is running unless the device has a network interface.

There may be other advantages or disadvantages to INDI or ASCOM Alpaca. Please contribute your knowledge or preferences if you are interested in this topic.

Re: re greasing worm wheel on 1100GTO original gearbox.

Joe Zeglinski
 

Thanks Harry,
 
    Good lead for AeroShell Grease-33.
May be a bit pricey – I paid $20 Canadian a few years ago, for the same thing, so it should be around US$15.
 
    Of course, the shipping would have to be by land, since it is illegal to ship “fuel” as cargo by air. I’m sure airport X-rays would flag it as hazardous material, if they tried, since it looks and smells (to chemical sniffers) like a bomb.
 
    If you zoom in on the tube base in that Amazon ad, you will notice the “manufacture date”. This must be an old 2014 picture (hopefully), but make sure what you buy, and before they ship, is no more than a year older than the printed date. The 2014 product would now be a year past its best-before date. Otherwise, you may be getting “stale dated grease”, from somebody unloading their old stock that can.t be legally sold to real aircraft maintenance mechanics.

A second occurrence of the same issue might indicate a deeper issue that needs to be addressed. I don't think you should be experiencing this kind of problem on a 2.5 year old mount. I'd contact George at A-P support and talk this over. Fiddling with the spur gears is not a normal thing to have to do.

HELP! Odd Mach1GTO PEMPro Results

gary imm
 

I have had my Mach1GTO mount for 2-1/2 years, purchased new in December of 2016.   I periodically check and update my PE curve, about once every 6 months.   Each time the curve was as I expected. Lately, my imaging has been OK but I have noticed some occasional strange "excess movement" in RA while guiding.  So last week I ran PEMPro, and the results that I obtained looked very odd and different than I had seen before, mainly showing up as inconsistency between runs.  The runs have some of the same general trends, but in some cases they are wildly different.


My setup:

Mount - Mach1GTO (Dec-2016)

Scope - Tak130

Software running while checking PE curve - ASCOM, APCC, SGP, PEMPro, CDC


Over the past week, I have tried many things to improved the results.  These include:

- I tried various runs on good seeing nights.

- I remeshed the gears numerous times, ranging from slight pressure to more significant pressure.  Moving the gears by hand, the movement seems smooth and perfect to me.  The gears move smoothly while tracking and slewing, and don't make any odd noises.  From what I can see, the gears and the worm wheel seem clean to me. 

- I removed all of the wires which pass through my mount, which I thought may be subtly binding & then releasing the RA rotation.

- I lightly greased the gears.

- I rebalanced the mount, with runs varying from east-heavy to neutral.

- I made sure the mount was polar aligned with Polemaster before each run.

- I always ran the PEMPro calibration wizard before starting each run.

- I tried various PEMPro run settings. 


No matter what I do, the end results look similar.  The results of the latest run, on a night of fairly good seeing, is shown here:

https://groups.yahoo.com/neo/groups/ap-gto/files/Odd%20PEMPro%20Results%20for%20Mach1GTO/


My mount has never been dropped, damaged, or even bumped to my knowledge.  I set it up in the backyard and store it inside while not in use.  It has never been transported, only carried. 


I would appreciate any help which could assist me in identifying the problem and finding a solution.  Note that guiding still results in good images for me.  My desire to fix this is more related to the fact that I love my expensive, well built mount and I want it to perform as it was designed to.



Thanks,

Gary Imm

    Here in Toronto, I had a similar problem locating a supplier of AeroShell-33, for my AP-900,  and even SHELL OIL Corp. would NOT sell it to me unless I bought a large quantity, perhaps a shipping palette full of them. They couldn’t figure out why a private individual would need it.
 
    However, I eventually discovered that I could simply drop by an “Aircraft Maintenance Supply” business, near the local major airport, and buy just one calking/greasing  gun tube of it over the counter. That’s enough for a lifetime supply for 20 or more scope mounts ! The dealer even wrote the “adjusted” expiry date on the tube he had on his shelf stock supply, normally provided to aircraft companies mechanics – since government safety regulations require that aircraft landing grease they use, like this, must NOT be older than 4 years since production. The grease components begin to separate somewhat from its oil base, if it is older.
 
    So, I suggest you check a nearby airport, even a small one, for aircraft maintenance suppliers, rather than going through the hoops of locating some specialty company, who would sell you some – and their grease supply might even be out-dated - while a major supplier would have fresher grease, with their constant stock turnover. Besides, being a volatile fuel product, it might be banned from quickly shipping to you by air.

But what kind of wear and tear I will see in those AP 1200 gear box gears, when I will open the gear boxes up for re-greasing my mount gears?
Any gears that have brass or bronze should not use grease with sulphor. MS means molybdenum-disulphide. That stuff eats bronze and brass.

Hello Astronuts,

I ran the Mach2 again last night with the 130GTX. The goal was to test the mount with unguided imaging. Seeing was pretty good with 3 out of 5 and some high thin clouds. I shot NGC2968 in Leo starting from the zenith to 2 hours past with 5 minute sub exposures. The mount was simply polar aligned via drift method and no other compensation or modeling was used. Drift varied somewhat due to atmospheric refraction but it did not affect the overall results. The idea here was not to get a pretty picture, rather it was to show the precision tracking of the Mach2 encoder mount. See screen shot below:

If the skies remain clear tonight I plan to do a PEMPro run to measure the tracking accuracy over a number of worm cycles. I hope to show the remaining few skeptics that periodic error is completely gone in our smallest production mount.

Re: [ap-ug] Re: New file uploaded to ap-gto

Miguel Morales <miguelmjr14@...>
 

Are there going to be any guided tests of the Mach2? I don’t think that I will be taking images unguided as I like to take exposures of 20 minutes or more. I assume that 20+ minutes is too long for unguided imaging.

 

Thanks,

Looks excellent. That is going to be a strong performing mount!

Hello Astronuts,

I ran the Mach2 again last night with the 130GTX. The goal was to test the mount with unguided imaging. Seeing was pretty good with 3 out of 5 and some high thin clouds. I shot NGC2968 in Leo starting from the zenith to 2 hours past with 5 minute sub exposures. The mount was simply polar aligned via drift method and no other compensation or modeling was used. Drift varied somewhat due to atmospheric refraction but it did not affect the overall results. The idea here was not to get a pretty picture, rather it was to show the precision tracking of the Mach2 encoder mount. See screen shot below:

If the skies remain clear tonight I plan to do a PEMPro run to measure the tracking accuracy over a number of worm cycles. I hope to show the remaining few skeptics that periodic error is completely gone in our smallest production mount.

I respectfully urge that any protocol be fully documented.

If he is wanting someone to review technical documentation for the missing areas of the last known documentation (firmware 'G' I believe) I would be happy to help with that process.

I did what I could to improve the AP INDI driver to the point I've used it for 2 years for all night imaging.  When I started it barely worked.  But it doesn't have some of the nice features you'd want for unattended imaging.  Without further documentation I have pretty much backed away from working on it as it does everything I needed at the time.   Just looking at the protocol traffic from the ASCOM driver in the logs is enough to tell there is a a significant fraction of the features of the mount we can't access at this point.

I don't think it's so much the amount of engineering that's needed that's the issue. While they can be involved, drivers on this level really aren't complex things. A better-documented wire protocol would certainly help greatly in any respect. Alpaca won't solve any problems in this regard, either, unless an Alpca service were implemented on the CP4/CP5 itself. While that would be cool, I have issues with certain aspects of Alpaca that leave me luke-warm about it overall.

If you look at an ASCOM debug log from the AP driver there are so many commands being used we have no documentation for it is clear writing and supporting a proper driver is just not possible without more support.

I still would not use it unattended imaging - but that is partly based on my poor experiences trying to have EKOS run an overnight session unattended compared to something like ACP or Voyager under Windows.

It starts fine with tiny movements in the star... then after 8- clicks or so it will lose the star and the mount starts doing calibration jumps across the sky! Another Mach1 user has the same thing. I'm wondering if any AP mount user has been using INDI and successfully guiding? (which driver?) I'm using AstroPhysics Experimental driver currently.

Re: ANYONE using GTO4 and INDI?

Jeff
 

We will be happy to assist in the development of an INDI driver. We are working hard to convert all of our University Astronomy equipment over to the LGPL v2+ INDI environment. Next on the list is an AP1200 with GTO4. We will begin serious work on that in the upcoming Fall Semester.

We can contact both Michael and Howard offline.
