Hello all,
I've been using my Phillips Toucam + GPUSB unit pretty successfully for guiding for the last couple of years. But, I find that I often have to move the scope off axis a bit to acquire a decent guidestar and this can cause drift in the corners off the images - something which isn't there when the optical axes of the imaging and guidescopes are aligned.
I've been considering purchasing a QHY5 mono CCD for guiding in the hope that its increased sensitivity(?) would stop me having to move the scope round to find useable stars for guiding.
Is this the case?
Have any who have made such a switch been disappointed or amazed at the difference!!??
Cheers
Doug
