Lagoon Nebula

First light with my new scope, a Celestron C6 with F6.3 reducer, and spent a lot of time dialling things in, checking collimation, back spacing etc.

I then pointed to the Lagoon Nebula and got 4 hours of 3 minute subs. Processed to a sort of SHO pallet using Pixinsight and PS I'm happy with this first go of an SCT. My outer edge stars still aren't perfect, I think I'm spaced too far out now but only by a smidge, so will keep tweaking but overall, this photo is only a very small < 10% crop of the captured frame, loving the focal length.

Gear :
Celeston C6
F6.3 Reducer
Celestron Autofocuser
HEQ5 Belt Modded
ZWO 071MC Pro camera at unity gain -5 degrees
L-Extreme 2" Filter

Very intense colours. Lovely framing, and nice small stars. Great stuff

How on earth did you get that colour palette with a colour camera?

The l-extreme filter captures hydrogen and oxygen. You then make a synthetic green and process it like you would a mono narrowband image. Works surprisingly well.

I tried doing it in Startools (I have the same filter) but had no joy. Yours is awesome
