the andromeda galaxy as an HDR

the andromeda galaxy is big and bright. the problem is the core is so much brighter than the rest its easy to blow it out. I wanted to try HDR techniques to prevent that.
This is a combination of 15 second,30 second,1 minute,3 minute,and 5 minute exposures,a total exposure time of 3 hours at iso 400

I'm lucky enough to live in a rural, dark-sky area of Virginia where the Potomac River joins the Chesapeake Bay. A few times, mostly in the winter when humidity is low, Andromeda is a naked-eye object here -- it's just a dim smudge naked-eye, not much better in binos. We had two good nights last week, I caught Andromeda both nights, binos.

My telescope is a 12-inch Dob, so astrophotography is pretty much out of the question, although I've had a little luck shooting Moon, Jupiter, and Saturn using a point-and-shoot camera held up to the eyepiece -- it's hit or miss.

ive never had success with them but you need large focal lengths to see details. like 4000mm+. a lot of people shoot short videos for planets and stack individual frames.

this show it with 344mm of focal length on an old sony a6000 camea
