Deneb and Andromeda again

Another clear, moonless night last night, so another astro session. This time I really wanted to try and capture the nebulosity near Deneb well, so I I took 19 2 minute exposures and stacked them. The resulting file after processing is about 4500 pixels across and has pretty good detail, I think it will an excellent large print.

I also tried using the 300 f/2.8 IS for astrophotography for the first time last night to get a better image of Andromeda. With the increased focal length, I had to drop the exposures to about 80 seconds and shoot wide open (at f/2.8). This also meant I had more images to stack (about 60). Again, I am pretty happy with the results, but I may need to tweak some of the processing just a little bit more.

Wow, those are really fantastic images!

Thanks. The Deneb image does make a nice 13x19 print, tried it this weekend. I'll probably try to get it printed at 16x24 sometime, should still be decent at that resolution.
