CCDAutoPilot results
Last night the first unattended multi-target session test was successfully run with CCD AutoPilot 5.
There is still coma in the edges due to mis-collimation and the angle of the CCD is not exactly 45°
Polar alignment also needs some adjustments, also the colors are not calibrated and the flats are not very good.
Nevertheless, here are the results (M5, M81, SH2-108)
M57
M57 Ring Nebula
Another test image. 1×1 Binning with Ha 13nm Filter, 880 seconds exposure. No darks, no flats
M13
M13 Globular Cluster
Test image with TS ONTC 12″
