AVX not slewing in right direction

#1

Post by jazzin »


Last night I had a Slew to problem in SGPro. Everything worked fine when going through my two star alignment and 4 star calibration routine. First thing I do after my Goto alignment is done is I do Frame and Focus in SGPro. So I connected all my equip and then opend up the sequencer and clicked 'Slew to' for the star Capella. This has always worked fine everytime I've done it before but this time when I clicked 'Slew to' function, the mount slewed in a totally different direction than where the star Capella is. Anybody else use SGPro and had this happen to them? It even slewed my scope into the tripod legs. Only thing I changed was Standard Time to Daylight Savings Time in the HC.

Check your Location settings - not Southern Hemisphere. And check the Time Zone - make sure you have "minus" UTC.

I've had this happen in another image acquisition software title, APT. My fix was to shut everything down (software, computer, telescope mount) restart everything, and then invoke the software in the order I have to to get everything to talk to everything. But I align differently than you do. I use plate solving to do my alignment. It's faster and since I've started doing this I've had no more "misdirection" problems.

Cheers,

Cheers,
Doing the AVX alignment routine is the only way I learned to get the mount to learn where it is in relation to the sky from my location. It's the same routine I've used since I learned how to do this back in 2016. It's always worked except for a couple times usually when I switch the clock in the mount from Standard to DST.

Anyway I think I understand what going with the mount now. For some reason it's not syncing with the last star I calibrate on. It still thinks it is in the home position. So I'm assuming if I tell the mount to Go to Home position after I finish calibration procedure, it will work.

Not sure what setting controls that function though
