Re: Question: How do I safety replace the CW shaft adapter (got it off, grease?)

Cheng-Yang Tan
 

Hi guys,
   So, after a few trepidatious taps with a mallet and a long T-handle allen wrench, I got off the adapter. Whew :)

I've always wanted to know this: Is it ok to put some grease or WD40 to the threads of the CW shaft to make screwing in the shaft smoother? Of course, I have on the back of my mind that grease and optics don't mix.

The gearbox is not attached to the counterweight shaft adapter. Use a large Phillips head screw driver and tap it with a hammer in CCW direction.

Hi Roland,
   So I don't need to disengage the clutches or the gear box?

   I can definitely tap with the best of 'em :)

Hi guys,
   I just received the new AP1100 CW shaft adapter with SS insert and I want to replace the existing one without the SS insert. I removed the CW shaft and my telescope and then in the park 3 position,  I inserted an allen wrench into the holes of the adapter and applied some force. Nothing moved. I didn't want to apply more persuasion because I was afraid to damage the gears because the clutches were still engaged and so were the spring loaded gear boxes.

   So before, I apply more persuasion, what is the safe way to do this without damaging anything?

Thanks for any advice.

Re: APCC Environmental Settings do not stick #APCC

Ray Gralak
 

Hi Eric,

It could be that your settings file has gotten corrupted. With APCC not running, try deleting or renaming, C:\ProgramData\Astro-Physics\APCC\settings.apcc, then start APCC.

You will have to re-enter your settings if that was the problem. Or, you can try loading one of apcc's backup files in:

C:\ProgramData\Astro-Physics\APCC\Backups

The backup files are date-coded in the filenames so you can try picking backups progressively back in time until you find one that works.

Does anyone have a recommendation? The Sky X vs Maxim DL?

I used to have a Paramount MX (PMX) which I have sold in lieu of AP1100 with AE and a soon expected Mach2.

I used The Sky X with camera addon and Tpoint on my PMX, but now that I do not have this mount, I am inclined to help the PMX buyer transfer the TSX license. I would like to know what the good folks here use on AP mounts with or without APCC.

Options I am considering

1. Continue TSX with Tpoint +  camera add on or use the imaging edition from Bisque
2. Use MaximDL, but not sure if it is as good as TSX. I especially liked the "closed-loop slew" in TSX; I don't know if Maxim DL has the equivalent of closed-loop slew, and if the planetarium sw of Maxim DL as good. I have heard of auto meridian flips of MDL and multi-star auto-guiding, plus integration with ACP. 

Thoughts?

Re: Model corrected coordinates through the command protocol?

Brent Boshart
 

Thanks again for your help Ray.   My goal is to do long focal length videography of ISS passes.  I use a closed loop method, query the current mount position, the satellite current position, satellite movement rate and then adjust the mount rates (with all that data) to keep the satellite in the center of the FOV.  Communicating directly with the mount using the command language (no APCC, no ASCOM) works very well.  But my limitation is the pointing accuracy of the mount as I can only do single star alignment (no compensation for any cone error etc).  I may have to do my own simplistic modelling to improve the pointing as well as minimize the cone error on my OTA. 

 

 

 

 

 

 

 

 

 

 

 







Re: Need help figuring out focal length for Stowaway and AP130EDFGT / Field Flattener and more for inputting into ASIAir Pro

Kevin Cook
 

Denice - Exactly what Kenneth said.  Start with the nominal focal length for your scope, shoot an image and let the ASIAIR software plate solve that image, and that will tell you the actual focal length.  In my case with an older AP130EDFS, the nominal focal length for this f/6 scope is 780mm but the actual focal length from plate solving is 834mm (with no flatteners or other elements added into the optical path).  Kevin Cook

Re: Model corrected coordinates through the command protocol?

Ray Gralak
 

Hi Brent,

Oh no... That's not good (at least for me). Is there a technical reason for that?
When caching is off, you are sending commands directly to the mount and not interpreted by APCC.

Does that mean that Horizons does not use the modelling either?
Horizons uses APCC modeling in APCC Pro. I previously said Horizons turns off caching, but that was incorrect. I was thinking of APPM.

The move rates sent by Horizons are real-time calculated from the NASA data and sent to the mount in real-time. So although RA/Dec read backs are the cached values, the open-loop move commands happen in real-time. And, the only time you will likely see a delay in RA/Dec is with a fast-moving object, but that will also happen in any polled system (e.g, a planetarium program).

Re: Need help figuring out focal length for Stowaway and AP130EDFGT / Field Flattener and more for inputting into ASIAir Pro

M Hambrick
 

If you have MaxIm DL you can also use PinPoint Astrometry to do your plate solve. You can use it with the GSC-1.1 catalog which can be downloaded free. 

You will need to enter the approximate RA and Dec at the center of the image and an image scale. The first time I used it to solve an image from my Stowaway I had entered the incorrect image scale, and it solved it very quickly anyway. When I noticed that PinPoint kept coming back with a different image scale on my Stowaway images, I realized that I had calculated the original image scale using the wrong focal length. I was using the native focal length of 612 mm, but since I have the 92FF flattener in my imaging train, I should have been using a focal length of 644 mm per the 92FF specifications.

Re: Model corrected coordinates through the command protocol?

Ray Gralak
 

Hi Brent,

Is it possible to get model corrected coordinates through the command protocol? See the example below. If I turn
"Point Corr" off in APCC then the coordinates match.
If you have RA/Dec caching disabled, you are going to get the mount's direct coordinates. With caching enabled, you will get the model-corrected coordinates.

Put the focal length that is stated in the specs of the scope. Then shoot and do a plate solve in asi air. It will then update the correct focal length into the field after sync to mount

What FL is good? How about Stowaway with a DSLR? Too much? Then just a 400mm lens? Or even less?
