HorseHead (B33 + IC434) & Flame (NGC2024) Nebulas

Unfortunately, I didn't keep the exact data. I recall it was a 90mm APO refractor and a color SBIG camera.

Added this data.

Hmm... You've surprised me! No, the image is certainly good for such an aperture and a single exposure. But I'm surprised that such modest equipment is being used at a remote observatory in the southern hemisphere—which obviously isn't cheap—to photograph an object that is visible from our latitudes too.
I thought that if you're paying, it should be for a good aperture, or for objects that aren't accessible from here.
Just my opinion, of course.
