Thanks. This is my first attempt at platesolving with any camera. Still learning.

Hi Marty, I'm not sure if you've platesolved with this camera before. I have the 6200 and find that I have to bin at least 2x2 to get a successful platesolve.

Thanks, Ray. This is very helpful. I am getting big images (17MB) but I did check 1/2 subframe and Auto Dark Subtract was unchecked. The computer itself is very fast (6-core Xeon processor at 2.7GHz)

#APCC #Mach2GTO

Hi Marty, The errors are coming from the plate-solver application. Here are some suggestions: 1. Instead of using GSC11, use USNO A2.0 or UCAC4. Note that you will likely have to download those catalo

I tried my first ever attempt at building an automated pointing model using APPM. (I've used manual T-Point runs in the past.) The plate-solves were all failing. I must be doing something very wrong h

#APCC #Mach2GTO

It could be a typo in the units. Remember that one RA sec/sec is 15 arc-sec/sec. I'll fix that in the next build, but it should not affect the tracking. -Ray

#APCC #Mach2GTO

Just to be clear, the first image was during real-time using the regular tracking, the second was using Test Tracking.

#APCC #Mach2GTO

It appears the first screen displays RA rate in arcsec/sec but the second screen displays the RA rate in sec/sec? Since there is 15 degrees in 1 hr RA to convert sec/sec to arcsec/ hr would be 11.0699

#APCC #Mach2GTO

Okay, I’ve been playing around with this, both using the Test Tracking and in real-time, albeit in my basement due to the clouds, and I am learning how this works, but I do have one relatively simple

David, If you attached a large file, it probably was stripped. To get the logs, please use the APCC log zipper utility (not the AP V2 Log zipper) and include all APCC and AP V2 Logs for the last day.

#APCC #Mach2GTO

Is this what you need? I can see that changing the system clock could make debugging more confusing. I can try it in "real time" one of these nights when the ISS makes a pass. Thanks.

#APCC #Mach2GTO

Hi David, I would need to see the APCC and AP V2 driver logs to see what happened. One possibility is that the computer could not send commands fast enough, but I don't know why any of the rates would

#APCC #Mach2GTO

Here’s what happens. You may even be able to hear the mount slow down in the background.

#APCC #Mach2GTO

Thanks for the info. Here's what I tried next. I did as you suggested and was able to get 1 hour's worth of data at 1-sec intervals, bounding the time where the ISS would be above the horizon here. I

#APCC #Mach2GTO

Hi David, 1-minute intervals are not accurate enough. You might try to do a 1-second interval. You can do this by specifying a start and end time and specifying an "equal interval (unitless)" step siz

#APCC #Mach2GTO

Okay, I'm trying to use A-P's Horizons to track the ISS, and I have a couple of questions. I was able to get the ephemeris data from JPL and load it into A-P's Horizons. So I have data loaded in there

#APCC #Mach2GTO

Thanks. “ASCOM” didn’t show up as an option, so I installed the MGBoxV2 ASCOM driver. I could swear that I installed it before, but I guess I didn’t. Anyway, it appears to have fixed it. Thanks.

#APCC

Hi David, Please make sure you have installed the latest drivers for the MGBoxV2 and that the Device DataSource is set to ASCOM as in this screenshot: -Ray

#APCC

I set up the meridian limits using APCC last night, and I have to say that it’s a very useful and easy-to-do process. It’s one of those things that you can read about, but you really need to do it to

#APCC

I’ve used my MGBoxV2 with APCC on my old computer with no problem, but I’m switching to a PrimaLuceLab Eagle 4, and I have a problem getting the MGBoxV2 connected. I’m pretty sure I’ve installed all t
