As Soon as I Launch PHD2 -- RA and DEC Go Nuts


Recommended Posts

About 3 weeks ago while on a trip to AZ I set up my Celestron AVX mount in the RV Park hoping to do some photography. It was the first time I had sat it up in some 6 months. The last time I had it set up all was working well. 

I did Polar align using my Pole Master. Quick Align on the mount having set the longitude and latitude for my location. I did a plate solve on 2 different stars and sync'ed my mount each time. I sent it to Orion and it quickly found Orion and plate solved on my desired target (Horsehead). Then I enabled PHD2 and it locked onto a star and started tracking. As soon as PHD2 started sending corrections, both RA and DEC went off the graph within a few seconds. It was as if PHD2 was telling it to go the wrong way. A few seconds later PHD2 would report that it has lost the star. I had recently updated ASTAP to the latest version.

I am looking for ideas of what was going wrong with my setup?

After an hour or more of fiddling with the mount settings, APT and PHD2 I finally gave up and bagged it for the night. Being in a strange new location was adding to the frustration factor. I haven't had time to retest it since I got back home. I am wanting to try to shoot a time lapse of the Lunar Eclipse this coming Sunday evening. Hope to have an evening before to attempt to test the system but cloud forecast is not good.

Within the settings have you got the reverse Dec after flip tab checked... If your pulse guiding then ascom already knows this has to reverse after a flip so no need to have this ticked

Is your guide setting on Auto, north or south( far right tab)
