Had an interesting session last night. PhD2’s SNR was all over the place but there were no disconnects or times out. Yet the mount ended up in a different position from where it started (i.e., the initial position I had set in SGPs frame and focus, confirmed by the values in EQMOD’s UI, which it slew to at the start of the sequence). And worse, I missed the target completely.
I need to determine why the mount was so far off when it finished and I don’t know if this is within an acceptable threshold. (Guessing it is a PhD2 problem, but looking for any assistance I can get.)
Astrometry.net’s plate solve reports that my final image is at
Center (RA, Dec): (323.855, 31.303)
Center (RA, hms): 21h 35m 25.230s
Center (Dec, dms): +31° 18’ 11.599"
but I started the session using the coordinates from Telescopius (EQMOD also showed those at the start), which were:
20hr 45’ 38"
30º 42’ 30"
When the session ended, however, EQMOD reported that I was at
20:47:42
+30:57:30
which also doesn’t match the values of the final integrated image that I got from the plate solve.
I don’t know how that drift between the start and end values, nor the location offset in the actual final image could occur, but they definitely impacted the resulting image and must indicate some serious problem.
