HI Everyone,
This has taken quite a while over several nights. The CNC spider on the Quattro has made such a difference with collimation holding for days. I think that the stock spider is the problem that has been overlooked in forums where people have been struggling with stock Quattro reflectors. I'm using the stock focuser which holds my kit with OAG perfectly without tilt.

RGB plus 208 x 300sec Ha, and 40 x 300sec OII and SII. Antila 3.5 nm. ASI 183 MM and MC. Quattro 800.

RC Astro Star and Noise Exterminator and Affinity. DSS.

Looking at what some others have achieved with this data I think I need to review my processing techniques! I chose this hobby as the learning curve looked long and interesting. I wasn’t wrong!

You have got the bones of a great image. I think your detail looks good but maybe the colour needs a bit of a review.

Thanks Paul,
Have made some adjustments. I think this is an improvement but I find the processing difficult!

The colour in the second version is less saturated so much better Chris. The teal colour is coming through in the core and the outer shells of the nebula are quite prominent. Looking good.
