I had some earlier data of Stephan's Quintet however the stars were not as round as they should be. I managed to shoot some more stars using 15 second subs and I imaged 60 sets in each of the RGB filters. Did a removal and a change of stars in the old image.

 

My intention, now i've corrected the issue of badly shaped stars due to cable drag, is to reshoot the target weather permitting.

 

As always comments invited however this is legacy data so will not be as good as a complete reshoot- the data in the galaxies is also victim to the same cable drag that hurt the original stars.

 

Clear nights to you all.

Still a nice image!  It’s cool to see this particular target up close with a C 14 being that I got a pretty nice image from a bortle 2 zone with my 130mm refractor and obviously the resolution was limited by the 910mm FL.  Definitely share when you’re able to reshoot the image!

Can you post your image?- I would be very interested to have a look as the 910 mm focal length is of interest as I'm considering the Delta RHO which has 1050 FL.

Sure can!  I think 1050mm FL would be great for this target.  It would fit NGC 7331/Stephan’s Quintet very nicely.

I love your image- nice round stars and full of interesting details. I note your observation as to how the C14 has pulled out a lot more resolution allthough I need a lot more data to make things smooth.. I just need a lot more imaging time. The weather is being uncoperative at present.

I feel your pain.  Ever since I got my Chroma Ha and Oiii filters for imaging in my bortle 8 yard I’ve had barely a window to even test the filters, and I’m trying to pile on hours but like you, the weather is being very uncooperative.  This image will look really great when you finally get the integration time to smooth it out.  Thanks for the compliment!  Good dark skies are to thank for that image.
