About this image

I have been imaging it for a few months now – image is a compilation of data from Jun20 through to Sept20.

Processing; Deep sky stacker, Pixinsight with final tweaks in Photoshop+ Topaz DeNoise AI.

The ASIair Pro is amazing, it is helping me so much.

Sometimes I think, Wow, I’m so lucky to be able to look into the past – happy stargazing all.
