IC 1848 Soul Nebula

Finally cooler and longer nights πŸ™‚ But the session started with a non-responding GEM28 after starting the guiding calibration… so annoying!​​​​​​​At least the rest of the night was problem-free… Details

NGC 281 Pacman Nebula

My DSLR doesn’t like these temperatures… Had to fight with background noise structures. Looking forward for the colder nights πŸ˜‰ Details

Cygnus Wall

650mm focal length is already to much for the whole North America Nebula, so I tried to capture the most interesting area of the North America Nebula. At least most interesting to me πŸ˜‰ Details

NGC 6543 Cat’s Eye Nebula

This time especially the right upper corner is problematic (left upper corner too, but not that much as the right upper corner).

Fly- and Spider Nebula

Yesterday I took the chance to shot the Fly- and Spider Nebula and some cluster neighbors, but had to stop after 1.5 hours due to clouds (in contrary to the weather forecast). Additional I had a forced 15 minutes break: my GEM28 had again a crash/freeze. I had to reset everything: back to zero position […]
