Experiment for FOV and to see what I could capture
Modified Canon 1100D & ioptron Skytracker
Zoom lens at roughly 100mm f5.6 = 5 x 4mins + 32 x 3mins + 15 x 2mins
Zoom lens at roughly 120mm f5.6 = 24 x 4mins
Nifty 50 lens at f3.5 5 x 5mins + 22 x 4mins
If I have totted it all up correctly and not left anything out it should be a total of 4 hours 19 mins.
