Re: Can smog effect autoguiding?

 

Hi Tom

>>>I just heard on the radio that there is a smog warning in my area.
Is this a possibility? 

it's very unlikely. you can open the log viewer and see if your guide star SNR has dropped significantly, but I would not imagine that kind of change


>>>am I destined to always have problems, just when all have been sorted out. 

If you are doing astronomy, yes you will always have new and exciting problems to solve :)

This is a major upgrade for GTOCP4 control boxes.  In addition to the Ethernet download method, we now have an option for USB/Serial updates. Be sure to check the version history for a list of the improvements. Some of these were implemented for the new Keypad version 5 software which will be available for GTOCP4 owners in the near future. 


For Mach2 owners, unless your mount was shipped in the last couple of weeks, this upgrade is for you too.

Thank you, thank you, thank you, for making the USB option available.  It was so much more straight forward and much quicker than the ethernet version I used for P02-07. It probably took less than 5 minutes from the time I connected the mount to the PC to finishing.  I no longer dread having to do future updates.

Ah, thanks Roland.  I didn’t realize that the “old” amp draw method only works with the original Mach1 – which I have.  Interesting.

As to Balancing, I am surprised that I don't find some sort of balancing tool in APCC.  Seems simple enough to sample the amp draw in both axis to see which side is heavier and then instruct the user with "scope is camera heavy" or "Scope is counterweight heavy" with some sort of % measurement. 

The Mach2 uses micro-stepper servo motors which do not change current with load. Therefore it is not possible to measure any difference between balanced and unbalanced. Just loosen the clutches and do your balance that way. With clutches loose you can attain very accurate balance manually.

 

In general, you cannot extrapolate from one manufacturer all functions to another manufacturer.

Hi there!

First day owning a AP mount which happens to be the Mach2GTO :)
Up until today my imaging mount was solely a 10Micron.  I bought the Mach2 to put in an observatory because having one premium mount I have been taking it down and transporting it 2 hours every time I want to do some back yard imaging or go out to the clubs star parties.

Now I have two good mounts so I don't have to do that!

Ok so I am used to doing things a different way and I think some things are pretty good ideas.  Two that come to mind first are Balancing and Polar Alignment.

As to Balancing, I am surprised that I don't find some sort of balancing tool in APCC.  Seems simple enough to sample the amp draw in both axis to see which side is heavier and then instruct the user with "scope is camera heavy" or "Scope is counterweight heavy" with some sort of % measurement.   I would have to imagine that the access to that data is there it just would need to be added.  But maybe it simply doesn't matter and balance by hand is more than fine?   You tell me.

The second thing is polar alignment.  I went into the Pointing Model tab in APCC Pro and clicked on the button (blueish color) that says APPM and it did NOT launch point mapper. I had to launch it from the desktop.  Once in there I looked around and it seems to have a lot of great information. But again, nothing that seems to indicate that it can command the mount to do something akin to The Sky X's Precise Polar Alignment where it uses the sky model to determine polar alignment error and asks you to center a star using the physical knobs. Once the star is centered, you are polar aligned.  This has been the way I did polar alignments for the last five years on a few different mounts.    Did I overlook this tool somewhere or is this simply something that nobody wants?  

How are you doing polar alignment ?  Are you all using the RAPAS?   Since I am going to be permanent on a pier I only have to do this once.   Just use Sharpcap and move on? 

I believe both of these features would be pretty nice to have and wouldn't require further software purchases.

Re: Balance helper by amp draw? #Mach2GTO

Woody Schlom
 

Micheal,

 

First off I have a Mach1, not the new Mach2.  But all my comments should apply to the Mach2 also.

 

  1. Balance technique #1.  Balancing the DEC access of the original Mach1 is a bit tricky as it has no gear/friction release for balancing.  So there was quite a bit of friction even with the clutch released.  But Roland suggested how he did it – using a low-tech fish scale.  And by golly, it works.  I have a new-fangled digital fish scale which works even better.  Basically you release the DEC clutch fully, lay out the CW shaft horizontal, and then attach the hook of the fish scale to the end of the CW shaft and gently tug straight up and read the weight on the scale.  Then reverse direction and gently tug the end of the CW shaft down and note the weight on the scale.  The goal is to get both readings to be the same.  So adjust the weights accordingly.
  2. Balance technique #2.  This uses the electronic technique you described – compare the amp draw in both directions, and adjust the CW until amp draw is the same in both directions.  And for this the handiest solution is to buy one of Powerwerk’s inline volt/amp meters.  It comes with PP connectors on both ends.  So you just plug it in between the mount’s power supply and mount – and with the CQ shaft horizontal, do the same as with the fish scale – except using the mount move controls to move the mount – and adjust the CW until the amp draw is the same in both directions.
  3. I use two methods for PA.  #1  The fast method (which I use 99% of the time) is using the RAPAS and a Polar Alignment APP on my Android phone.  The APP takes the phone’s current time, date, and location and displays an identical RAPAS reticle image on the phone – with a white dot where you’re supposed to put Polaris.  And then you just adjust the Az and DEC mount adjustments until the real Polaris in the RAPAS is in exactly the same place where it is on the phone’s APP.  Done.  With just a little practice you can do it in about a minute.  And it’s plenty accurate enough.
  4. #2 PA method I use.  PemPRO.  This basically is a camera assisted speeded up drift alignment.  It works well, but takes me a whole lot longer than the RAPAS method.  And to be honest, about the only time I use PemPRO for PA is to calibrate and align my RAPAS.

 

Woody

Re: Using other side of right ascension drive gear

Does this apply to a 900GTOCP3?
Does it impact the PEC curve?
Yes, all our mounts including the 900, 1200, Mach1, 1100, 1600. They all work the same way. No impact to the PE curve because the PE is a function of the driving worm, not the worm wheel.

I use the Polemaster, which I have had for some time, and it works fantastic. In fact the Mach2 comes ready to install.
 
Other people use Sharcap with fantastic results too. RAPAS I have never used it, but from what I have read it works perfect too.
 
What is vital for an AP mount is good polar alignment.  Once done, with the Mach2 I never needed a star alignment or anything like that, I just used SGP and slew the mount to a random place in the sky and then a Solve & Sync and that would be all (then you can do the modeling using APPM).

yes this is a solution.

 

But this is supposed to be an automated system, starting in the evening and parking in the morning. Having to insert a GoTo Park 3 in front of the start-up procedure – this not being an ASCOM command – is not an elegant option. We might insert Polaris as a dummy target for the evening preparation but this is a kludge.

 

I would expect to have some option like „intelligen slew“ inside the driver to prevent this to happen.

We have an AP-1200 mount carrying a 16“ f/5 Newton. The scope must be parked at Park5. As the system is installed at 50° North, the declination of the Park5 is 40°.

 

 

 

 

Now, every time the mount does a GoTo from the park position to a target on the East side and having a declination lower than 40° (and a lot of them targets are there) both axes start slewing at the same time. The net result is that the telescope first makes a sharp nosedive and only later starts pointing back to the stars. This is between bad (the mirror moves in the cell) and awfully bad (the scope makes a hard landing).

 

 

The Mount has a CP3 controller. For the firmware version I would have to check (the system is remote). The ASCOM driver is at 5.30.10 level. No APCC.

 

Is there an option to tell the mount to delay the DEC axis until it is safe to start it? Is this function only available in APCC? Would an upgrade to CP4 help?

This is between bad (the mirror moves in the cell) and awfully bad (the scope makes a hard landing).

 

 

The Mount has a CP3 controller. For the firmware version I would have to check (the system is remote). The ASCOM driver is at 5.30.10 level. No APCC.

 

Is there an option to tell the mount to delay the DEC axis until it is safe to start it? Is this function only available in APCC? Would an upgrade to CP4 help?

 

Kind Regards,

Horia

We have not yet begun notification for the current run of 1100GTO mounts.  All of our customer service (and tech support) staff are working from home to maximize safety, but that dynamic does slow us down a bit.  At present they’re focusing on getting Mach2s and 130GTXs to folks in time for the holidays. 

 

Thanks for your patience!

Thanks for the update Roland.
One quick question - Are people being notified yet? Just trying to figure out if I am part of the list, although, I will say this, I did join the list fairly late.

Thanks!

Re: Setting Daylight Savings Time Using ASCOM V2 Driver

Dale,

 

I obviously misunderstood what you were getting at.  I will look at this later today.  If it doesn’t work, I will need to implement Roland’s recommendation and work off of Universal time.

 

Thanks again

Wendelin,

 

I was referring to the two options in the ASCOM driver for keeping the mount's clock sync'd with the PC's.

If you use only the ASCOM driver, open the A-P ASCOM driver configurator and expand the Advanced tab. Refer to the attached screenshot for the options, with a red box around them.

 

Having the "Sync Mount Time at Initialization" and "Keep Mount Time Synced to PC Time" option enabled should do what you want to do provided your PC's time is also correct. I believe the mount itself operates in UTC internally; the timezone offset is for display purposes. If you operate the mount with the driver and these options on, you should never have to worry about the mount's time, regardless of tz or dst status.

Dale,

I don't have APCC on my system.  I wrote some programs that control the operation of the mount, scope and camera through the ASCOM driver.  Since the time change, and because I have been lazy, I didn't update the CP4 to reflect standard time rather than Daylight Savings time.  This has caused a couple of mostly annoyances.  First, the mount thinks that all stars in the west are at lower altitude than they actually are.  This causes the code to abort a photo if the star is too low on the horizon.  The code I have written also reports back the altitude at which an exposure starts and ends.  These are incorrect as well, which impacts any star intensity corrections that get performed later.  If I could change the daylight savings time switch with software, it would simplify things greatly (as well as making sure that I don't forget to do this manually which usually happens).

Is there a way to set Daylight savings time or standard time using the ASCOM driver?  I know this can be done using the Keypad, but I usually don’t have it connected to the mount.  Software that I have written to control the mount has altitude limits in it and I have noticed that since we switched back to standard time the mount thinks the objects are lower in the sky than they actually are.


GMT offsets are automagically handled by the driver/APCC. Your computer having an up to date timezone database is how is the is possible, where maintaining such a thing on the keypad is impractical.
