I am supposed to leave for a dark sky site 1,000 miles away tomorrow and, of course, I'm having major issues the night before. I was planning on running a through quick setup tonight just to make sure everything was calibrated properly and I found my mount is having a major issue, and I'm really hoping it's user error. The mount starts up just fine, slews normally (I think), but PHD's graph jumps straight off the chart with in 10 seconds. Even if it were just having trouble guiding, I would think it would stay more aligned than that. This makes me think it's the mount, no? However, I took a couple 120s subs and the stars seems reasonably round.
The last time I had the mount set up I attempted to use plate solving for the first time. I used SGP's platesolve2. It seemed to slew the target alright but then had an issue solving. I don't even remember what the error message was, but I thought nothing of it and planned to try it again another night. Is there a possibility this could have changed something to cause this?
I use a USB to serial adapter with ASCOM. Sharpcap said alignment was "Excellent"
I tried going back to the factory settings on the mount: no luck?
What else can I try? Please help save a trip!!
If it matters: WO 73mm scope, ASI1600MM, Orion 60mm guidescope with ASI120 camera, running SGP, PHD, ASCOM
