Re: Trouble with MaxDome II slaving to APPM

This really isn't the right forum for MaxDome-II support.

Not sure why it wouldn’t be...

APPM’s calling the shots in regards to the maxdome moves, so I betcha I’d be calling for help here too. 

Funny how some people seem to first think of integrated systems issues as if all problems can only be solved by troubleshooting single component as if it were sitting alone.

Seems pretty obvious to me that when two (or more) pieces of hardware and/or software are integrated together, there are not so many other options but to inquire for help from the parties involved (be it a manufacturer, developer, vendor, etc.) 

I unfortunately can’t be of much help to the op’s issue, but man I would definitely not discourage him asking for help here about this !

This really isn't the right forum for MaxDome-II support. Diffraction Limited has their own support forum and there is the Observatory forum on Cloudy Nights.

Is this something that has worked reliably in the past and suddenly started to fail?

I would double-check your az encoder mechanical setup and your MaxDome-II ASCOM driver parameters. Extraneous light near the az encoder can fool an optosenser.

Hi. I'm trying to run APPM with MaxDome II. The first image attempt at the zenith fails due to the dome being 180 degrees off. The scope is on the west side of the mount / counterweights on the east.

Re: APPM - error

Ted Mickle
 

Ray,

I ran my first-ever APPM model three nights back, a 95 point model.

Since then, using APPM I’ve run hours of 900 second narrowband imaging unguided and marvel at the small round stars, even in regions of the sky that were not included in the original model (created with a Tak 130, 1100 GTO and QHY 600M).

Is this particular 95-point model only applicable for this equipment, image scale and imaging season?

Thanks for APPM - it’s transformed my astroimaging.

We might ask you to run this if you have a dramatic pointing or tracking problem with a model, which doesn't appear to be the case. You are better off using this time for imaging!

I did a 300, 600 and 1000 second exposure after the APPM model was applied and I had round stars with no
guiding even at 1000.
And at a good HFR of 3.48 (average is often higher even when guiding).
My max before the model was about 60-90 seconds and I'd still see eggs.

Re: Mount Synchronization Memory Lapse

Ray Gralak
 

Hi Jerome,

The first thing to check is that latitude/longitude/time are correct (on APCC's Site tab). If any of those are wrong, you can have proper RA/Dec, but the wrong Altitude/Azimuth.

If you are not running the latest APCC, you should update. Some of the earlier versions would only try to read Lat/Long once, and if the mount was not powered, APCC would use Lat=0. Later versions of APCC will try to read Lat/Long more robustly.

But to answer your question, one way to restore mount position is to:

1) Move the mount to the park 3 position by loosening the clutches and manually moving the scope, or via move buttons if you are remote and have a camera viewing the scope.
2) Tighten the clutches if you had loosened and manually moved the mount in the previous step.
3) Use APCC or the ASCOM driver to park the mount at the current position
4) Use APCC or the ASCOM driver to unpark from the Park 3 position.
5) Slew the scope to someplace away from Park 3.
6) Do a plate solve and recal to regain precise sky position.

Another way to do this is to do an All-Sky plate solve and recal. But you will have to temporarily uncheck "Prevent errant RECALs" in APCC's advanced settings. That is, after successfully recalibrating, go back into APCC's advanced settings and set the checkbox option for "Prevent errant RECALs" .

Hello,
I have a nice new camera attached to my Mach1 but I failed to check the balance before messing with the
camera. The scope is now way out of synch with what I see in ACP. I have run the ACP findlostscope script
and it says it corrects, but it does not. The fine team at Astrophysics saved my buns on this one time in the
past with another synchronization procedure purely done through APCC... but I cannot remember the
procedure nor find my notes.

Can somebody tell me what the procedure is?

The ALT reading on APCC and APC differs by 40 DEG.

BTW, the new lightweight camera is a ZWO ASI 6200... it does not produce lightweight files.... they are
100MB...

Just for storage in the house, transport to the car and from the car to scope setup. Will have see how the system work in real life.

Re: APPM - error

Ron Kramer
 

Thanks Dale.  I made several tweaks including your full-frame, bin2 and its working great.  THANK YOU!

I always had to guide at over 60-90 second exposures.  After APPM last night I did 300 sec, then 500, then 800 then 1000 second exposures and all had excellent stars and low HFR.  I'm amazed. 

only problem was APPM sometimes didn't want for the dome to slew/settle. (about 10% of the time).  But with the scope 1/2 way in the slit it was still able to get enough stars to solve.

Hello Guys,

https://www.cloudynights.com/topic/767964-lets-torture-the-mach-2/page-3#entry11371098

Can someone please post a reply to the confusion that Mr. Wang's post is causing about his Mach2 not being able to carry his TOA telescope. We have communicated with Mr. Wang and sent him instructions that will fix the issue, but he has not posted anything further. he will not be able to implement the fix for several weeks because the mount is at another facility.

For sure the mount can carry the TOA telescope and much more weight. We discovered a small error in his parameters which he can fix easily with a simple command.

https://www.cloudynights.com/topic/767964-lets-torture-the-mach-2/page-3#entry11371098

Re: APPM - error

I got it working, not SURE what I did - other than I went full frame and Bin2 for ASTAP.  It's about 3/4 through the model as I type this. 

I do have some minor issues with APPM not waiting quite long enough for the dome to slew and settle.  9 out of 10 times it does but sometimes it's hasty and the dome is 1/3 over the scope.  Luckily I picked up enough stars to still solve when this happens.
