Which Guide Scope?
I have two WO Uniguide guide scopes, a 50/200mm and a 32/120mm. I’m unsure which would be the better one to use with my Askar 400/F5.6 Refractor.
The guide camera is an ASI 178MM and I either image with an ASI533 MC Pro or an ASI 1600MM Pro.
I’ve checked out a couple of the online Astronomy calculators but I’m none the wiser.
Any suggestions would be most welcome.
