The Orion G3 has fat pixels, but can it find and lock onto stars for off axis guiding, at a high focal length? Lets say FL between 1-2m

Would depend on the speed of the scope, and the willingness of the user to bin it if need be.

 

My favorite piece of gear is my SBIG ST-i, it has big pixels and has no issues picking up any stars, regardless of the field presented.  I've used it in everything from my VSD100, to my EdgeHD at it's slow native F10, and I can always get at least one solid guide star.

I am finding there is some subjective opinion on a good off axis camera. Some people dont want to rotate the OAG at all, when I fully expect to prepare my OAG angle ahead of time using software.
