Description

Stephan's Quintet- Don't they look a bit like Christmas Teee ornaments?

As the name suggestes this is a complex 5 galaxy group, where some galaxies are violently colliding and will likely merge together eventually. The orange coloured galaxies have a physical association, a true galaxy group, known as Hickson Compact Group 92.

This is a SMALL target even for my 11inch scope and was a challenge to process due to bad flats and messy colour data.
But thanks to some recent videos by @Adam Block  and Russell Croman on the new Blur X 2.0 and the “correct first” I was able to save my colour data. If you have a big sensor camera and with small pixels and aberrations in the corners you NEED to learn more about it. 
I know I praise his programs a lot but honestly without Adam's work and the support he provides in his member forum I would never have been able to sort out, my technical problems and process this data so well.
Shot December 20th 2023
NGC7320, 7320c, 7318a 7318b 7319 and 7317 Also known as HCG92 and ARP319
Celestron C11 scope 0.7x reducer at 1960mm focal length
4 hours of 180 seconds Luminance data ( ASI 2600MM)
3 hours of RBG data from 2022 (ASI 2600MC)
Processed with bias, dark and flat frames (taken twice due to light leak)
Guided with the Celestron OAG and the ASI174MM ( best guide camera for this setup and I have tried a couple)
Some Star Spikes added for the widefield view since there was nothing much else there.
Merry Christmas everyone!
