After battling my new to me mount for a while and learning auto guiding I finally got a good night of clear skies with no equipment issues last night. It was also my first capture using dithering and it seems to make a huge difference in noise and i chose to gather more data rather than capturing dark frames. This is my first planetary nebula.

 

The difference in exposure times is because i had around 45 minutes of 120s exposures from a test session and they improved the final result.

 

I am pretty happy about the result, maybe a bit over-saturated in the reds. Not too happy about the brightest star either but i am not sure what can be done about it. Overall i am happy to be imaging again and looking forward to fall/winter when i can get going much earlier in the night and gather more data. I do no think i will be returning to this target for now, i think my fall project will be an M31 mosaic.

 

Processed in Photoshop using Astronomy Tools Action Set plugins. It is cropped a good amount since it is a small target.

Nice image better than what I have been able to accomplish.  Keep up the great work!
