That would be about the FOV I would expect for the 294, more or less the same as I have now using the ED72 (350mm focal length with the reducer I am using) Being ten second subs it certainly shows the photon sucking element of F2 compared to even F4.9

The biggest tracking issue I found when using my mount Alt-Az (Orion Atlas Pro) was that you absolutely had to level the base with a spirit level before putting the mount head on, ignoring the built in level. If you did not do that the goto and tracking accuracy suffered right from the start, get it right and both were good all night.

I have never used Sharpcap for polar alignment so I cant comment on that.
