Thanks guys for all your replies and I have taken all of your advice. I am actually quite interested by the revolution imager r2. The only thing I am confused about is why it doesn't have an HDMI out? Is that to save space or am I missing something entirely? Also, there is obviously some exposure time needed in order to create any live footage etc. so I was just wondering, is a goto dob sufficient in keeping an object in the centre of the frame across the sky for astrovideo use? Is anyone aware of somebody who has done astrovideo with a goto dob? Sorry about the questions guys but I really don't want to make a wrong purchase! hahaha
Cheers all, Harry
