Need to know about how to work that new mount or scope? Got tips on how to make it easier?

Flats without aperture control

Postby Terrierist » Thu May 17, 2018 11:48 am

Thanks for reading.

I'd like to take some flats for image processing, unfortunately, My Nikon D7500 doesn't have the aperture control that other earlier Nikons have. Would it be OK to take flats in manual mode and guess the exposure roughly by adjusting the shutter speed and leaving original ISO in place?
