I'll be starting astrophotography soon (as soon as I buy a tracker), I already bought a Nikon D5300 and a Rokinon135mm lens to start. However, I have a question: Is there really a need to use a Bahtinov mask in this case? Wouldn't it be enough to focus the lens manually on infinity and that's it? Perfect focus?
I'd also like to know if it would work if I made a Bahtinov mask myself and just put it in front of the lens. Is there any distance that should be between the lens and the mask?
