Yes, exposure time was 900s.

Are you doing 15 minute exposures? The dither distances and settling look fine from a PHD perspective, although I can see a big spike in guidestar SNR roughly every 900 seconds -- Brian Brian

I also posted the same question on PHD2 forum.

Since both SGP and PHD2 have been used by many customers, I am looking for suggestion on Mach2 mount debug.

Here is the log: https://openphdguiding.org/logs/dl/PHD2_logs_xGZF.zip I have not used the log before but I think this is the dither causing issue. I then restarted the sequence by turning dither

Hi Jerome, They can be two separate connections to the telescope - one from ACP and the other from MaximDL. In your script, I see that ACP is disconnecting from the telescope, but I do not see a call

You will need to look at your PHD log file to see what PHD is sending to the mount. I assume your dither is set to move the mount at 1x sidereal for a fraction of a second, is that correct? If you are

Beautiful! Well done Rolando!! JimP Get Outlook for iOS

Ray I am still confused since that call is right at the top of the Shutdown Script. I changed the order of the shutdown so that the last thing powered off is the mount and I still have the driver

Not sure what the issue is and whether it is mount related, hope someone can help me out. I have been using SGPro + PHD2 + AP mount without any issue for years, but recently PHD2 often loses guide

One last image from my recent Hawaii trip - the Fornax Dwarf Galaxy. I was fortunate to have good seeing conditions for my Luminance exposures. Next night I tried to get RGB but the seeing

It may be just an anecdote, but I just upgraded when I did it without removing the previous version. The Eltima drivers updated fine. Maybe I got lucky?

David, What do you mean by "Eltima is still not downloading"? -Ray

After a few days of troubleshooting dysfunctional APCC virtual serial ports a windows rebuild fixed my issue.

Ray, The Eltima is still not downloading. Windows must be interfering in some way. I going to reinstall win 11 and restore the computer to an earlier date. David

Yes, I was also puzzled by the dual designation of 2903/2905. Rolando

Ah yes, I forgot he as the color version. Yeah, debayering is going to blow that footprint up a bit earlier in the processing chain of events. The music labels for the genres of music that I (used

Thanks for the information, Bob. The program (APCC and AP V2 Driver) was working fine on Win 11. I'm going to rule out the physical ports as an issue since it's the same computer. David Burrell

You can try this BETA version of APCC Pro, which has a newer version (V10) of the Eltima ActiveX control and
