Re: how to clear APCC/APPM model

Simply delete or rename the file.  The default path is:  C:\ProgramData\Astro-Physics\APCC\Models\ ApPointData-yyyy-mm-dd-hhmmss.pnt   I would rename it and then delete it only after you are certain you will no longer want it.

Is there a way to completely clear an APPM-generated model from APCC?

 

I see i can disable pointing and tracking, but i want to remove the model completely from APCC

 

thanks

Re: Doubt about upgrading from APCC Standard to Pro #APCC #Mach2GTO

 

I just did that upgrade myself just a few weeks ago and had no problems. It installed alongside APCC, so you'll have both available until you're sure of the switch.

I embarrassingly was confused about APCC, ASCOM, and the AP V2 ASCOM driver versions. They're three different things, and all get used. I had an old version of the AP V2 ASCOM driver, and it caused me problems with PEMPro. It's a good time to update All The Things.

Anything else I should know?

Good morning,

Using my Mach1 and APCC-Pro/APPM I took this image over four nights without guiding.  I used a Takahashi FSQ-106EDX4 and modified Nikon D800e to collect about 7.5 hours of sub images.   The ability to image without guiding is amazing.  Thanks to all the folks at A-P for making such nice instruments!

Re: Mach1 and GTOCP4 Yellow Light

Roland Christen
 

Don't plug the Dec cable into the RA gearbox. No purpose for that. Just plug the RA cable into the Dec gearbox and see if that motor runs at the sidereal rate. See if the light turns yellow.

A) If the light turns yellow the problem is with the cable or controller, not the mount.

B) If the Dec motor runs at sidereal rate and light stays red, then the problem is with the RA gearbox and RA motor.

You can call our tech support at the AP phone number if you have any questions.

OK, I didn't thin that I can move the control unit so that both cables reach when swapped. I'll try that one more time today when I get home. If that fails, should I just call to 815-282-1513 number? Any specific person I should talk with?

Re: Bad X scale?

 

I had some good luck this afternoon following the hints below and writing my own set of options for the solve-field program that drives ANSVR.

I set my own values for field width to 25 min and 100 max which covers the range of my two telescopes. Then I found that it actually runs really quickly with the --guess-scale option, since SGP does a pretty good job of populating the FITS file with pixel data.

The root of my problem appears to be that I needed many more index files for smaller fields of view. The recommendation I had overlooked (or didn't understand) on the index downloader was "20% of your smallest field." After adding about three more layers of indexes, it appears that all of my failed solves from last night run pretty quickly.

When I was solving plates from the Traveler, I actually had about the right set of indexes on hand. On moving to the long AP180, I find that I need a lot more of the smaller field of view indexes.

Thanks so much for the hints and tips!

For ANSVR, the most important factor is setting the field of view.  For other solvers, like ASTAP, there are other factors, but I use ANSVR almost exclusively; although ASTAP may be faster.  Search the forum for ASTAP or plate solve.

Here is my entry in the Additional Solve-field arguments      --no-plots --scale-low 40 --scale-high 90 --scale-units arcminwidth

Re: Bad X scale?

 

Good stuff, thank you! I'll see if I dig out the failed plates and try them out.

Re: Bad X scale?

 

Thanks Ray, that's a point, but in fact I may not know my image scale exactly. I can get a number from successful plate solves. Maybe that actually is exact enough. The measurement from PEMPro using star trails has a little uncertainty to it.

I understand that a "Bad X scale" is a sanity check for a "successful" plate solve that is most likely wrong.

Right now I'm getting different success rates from the local ANSRV server and the online Astronomy.net version. I haven't yet tried using the online instance for collecting a point model, so that will be my next test. The failed solves that are not "Bad X scale" are all timeouts. I'm attributing that to an under-performing field laptop.

As I see it, the main trade-off between local solves and online solves is the bandwidth and transmission time required to upload the images to the server. In my case it might be offset by the lousy compute performance of my local machine. My net connection from near home will be a cell phone hot spot, and from my desert location it's WiFi to satellite internet (I think).

Does anyone have suggestions that might make the local plate solver more viable on busy fields? I haven't had much luck using settings to reduce the number of objects processed -- in fact it seems to fail more quickly.

Best regards,
Mojo

Morris, raising the tolerance might be okay if you don't know image scale exactly, but not if the image scale is already known.

When you see "Bad X-scale" that means even though the plate solve was successful, the image scale (and RA/Dec coordinates) were probably wrong. That is, it was a bad solution and should not be included in the model.
