I am using a Nikon Z6 with William Optics Z61 II and a Radian triad ultra quad band filter. I had a good imaging session with it one night. I focused on the moon and I found that the stars were pretty sharp. However, during my second imaging session, my stars were a little bloated. Since, WO Z61 II comes with a Bahtinov mask I want to use it, but the problem is I can’t see any stars. Neither in live view nor in the live view mode of APT (which I think is the same). Can someone help me with tips on achieving a good focus with my current setup. Am I missing something? Should I first find a bright star, maybe Polaris, focus and then image my target?
