Messier 31 – The Andromeda Galaxy Mosaic in 8K resolution by Frank Schmitz, Osenau Observatory – Odenthal, Germany. The mosaic was shot with an 8″ Lacerta Newton, a ZWO ASI 1600 MM pro camera and on a Skywatcher EQ6-R Pro mount. Total exposure time of this LHaRGB mosaic is about 36 hours.

“Wow, what a saga that was to put the mosaic together. This is my first LHaRGB mosaic ever and I had quite a hard time to match all the intensities … especially for the color channels.

In the end I kept adding subs to low quality panels in order to even things out and zoooom I ended up with 36 hours of integration. My longest integration so far and by far the longest pre and post processing of all of my previous images.

Fun fact: My last two images (Melotte 15 and the Pacman Nebula) which were both also 9+ hours were only shot while waiting for M31 to rise 😉

I encourage you to have a look into the full view: NGC 206, Cepheid Var 1, the core, the HA regions, small faint structures in Messier 110 really profit from the high resolution and the exposure time.

I hope I did this wonderful target justice and I hope you like it! Let me know what you think!”
