Hi,
I had my first go at widefield last night with my canon 1000d and the 18-55mm lens.
didn't really check the f stop but now that you'll mention it, is there a relation between the fstop and the aperture and are both independent of each other (i'm guessing 18-55mm is the aperture size)?
bigger f stops would mean less light, longer exposures like in telescopes?
I'm new to photography concepts so lots to learn.
if I set the lens to 18mm and piggyback on an eq mount, would that be sufficient for a start at widefield?
