Here we utilize the PHD2 software to create and review a baseline analysis of mounts

Calibration (2020-11-11) |
Observations Can't complain on this calibration. |
Guiding Assistant (2020-11-11) - 52 Minutes |
Observations Got some drift going on here in the RA axis, but I don't think its horrible: RA Drift = +0.35"/min, DEC Drift = -0.09"/min Polar Alignment Error: 0.3' |
Tracking (2020-11-11) - 46 minutes |
Observations Real issues with the RA axes. Drift in the guiding assistant (above) would indicate PHD is fighting with the mount to keep the star on track. For imaging at FL of 2800, I'll need to have about 0.75 RMS, Not happening on the RA axes. here is the numbers: RA: RMS=0.33", Peak = -1.08" DEC: RMS=0.33", Peak = 1.10" Total: = 0.46"
Under these conditions I could image at FL of 2800 and get good images. |
More information on this mount can be found here. This is the condition when purchased. We are definitely having guiding issues. Looks like RA is were we need to focus. I Took the scope out the next night to get more data, and noticed that the RA motor gets hot and sometimes makes noises. Also getting "RA axis Drag" notification. Looks like some adjustments are needed here.

Observations Our DEC seems to be pulling to the left here. |
Guiding Assistant (2020-11-11) - 52 Minutes |
Observations Got some significant drift going on here in the RA axis: RA Drift = +2.0"/min (YIKES!), DEC Drift = +0.06"/min Polar Alignment Error: 0.2' |

Observations Real issues with the RA axes. Drift in the guiding assistant (above) would indicate PHD is fighting with the mount to keep the star on track. For imaging at FL of 2800, I'll need to have about 0.75 RMS, Not happening on the RA axes. here is the numbers: RA RMS=2.20", Peak = -13.80" DEC RMS=0.59", Peak = 2.25" Total = 2.28"
Got some issues with RA I'll need to work-out. |
