NGC 7023 Iris Nebula

I’m very happy with this result of NGC 7023 🙂 I tried the Iris Nebula a few weeks ago from my home. Just 20 minutes (13 x 90s) at 280mm without guiding. But that’s not camparable with this one… I was very careful with the polar alignment and balance. And I had luck. I did a test […]

Cygnus Loop

280mm @ f/5.6 What a wonderful clear night on Gurnigel in Bern @1600m. But it was a little Power-Nightmare for me… First, I forgot to load the spare batteries of my 100D. So I had only 1 battery (~2h) for Milky Way, Location and Equipment… Second, I’ve planned to do 4h of lights (80 subs […]
