starnet Actually I noticed something with tracking. I have very good results at higher celestial altitudes (declinates). I mean when I shooting in Cassiopeia, my frame rejection is very low. Last night I collected one hour exposure of Pacman Nebula in 93 minutes. As I start shooting lower declinations, the frame rejection start to increase. In the Pisces the rejection is over 50%. I could collect 50 minutes of exposure in around 2,5 hours of M74. Then I slew to M1 and 63 minutes of exposure was taken in 2 hours and 10 minutes.
Pacman Nebula: 56 degrees, M74: 15 degrees, M1: 22 degrees. The higher the declination the lower the frame rejection. This is obvious anyway, because the stars move faster closer to the celestial equator. But the difference is very significant.
