Description

Everybody who follows my images knows that I love to play around with this area of the sky, and this image is not an exception. Yes, it is an OHaHb image, conventionally processed as I would with an SHO image. Personally I like this representation better than the standard color assignments (mostly HOO), it just gives a shine to it that looks interesting.
And yes, this is a first light of my Christmas present!! Another known fact for those who follow me is that I hate (well ... maybe a strong word for it, but comes close) mosaics (I might have found the reason for it, will investigate), and well, what would be a solution for that? A short focal length together with the ASI 6200. 5 degrees it is, just love it! And the setup could not have been easier, follow the 14 cm rule from exit to chip, and voila, tha back focus is done, as easy as it sounds! And the whole train is at M54, also a super plus! Only remaining problem is the auto focus with the ZWO EAF and SGP, it came up with a wrong lowest point, I need to play with some parameters I believe to get this dialed in. If anyone has experience with this focuser on the ASKAR scopes, please let me know, I would appreciate any information.
What impressed me most was that I was able to capture the hydrogen clouds around those 2 iconic objects. They are not in the standard red, but I like the little bit mysterious way they came out. 
I had to almost completely throw away the green channel for the stars since for some reason they created an awful halo around the bright stars. The red and blue filters were not perfect either, but manageable, although I would have liked them to be better.
Version C shows my new setup, I like the lightness of this one as well, my body appreciates it.
