Thank you! And my info is right on the photo: two fragments, 42 and 30 minutes total, with subs of 60 seconds each for both.

Alexey, did you stop down the lens aperture, and if so, to what value?

Honestly, I don't remember exactly. I shot without guiding and counterweights, so I used relatively short exposures, which means the aperture was most likely wide open.
