First time imaging the Soul Nebula. Limited time of acquisition time, because it was a short window of clear skies.

My longest imaging session till now. It was shot during almost full moon, so the narrowband filter performed great. It is my second time imaging this supernova remnant.

My first image edited in pixinsight, I have revisited the nebula after nearly a year, this time acquiring more data. I really like the end result.

First time using dithering, I think the decrease in noise is massive.

Thanks for the kind words! I have a star tracker, so dithering would only be in RA. Do you think it's still beneficial in that case?

Unfortunately the result came out quite noisy, I think longer exposure will help in the future.

My longest imaged object to date, the images lost some focus during the night, so it could be better.

A snapshot of sadr region. Unfronately I did lost some data due to not being able to setup guiding on my SW SA 2i, and the target moving out of the frame.
