Leo Triplet wide-ish field

344mm isnt exactly galaxy focal length but I gave it a shot anyway. Not much nebula stuff around for a bit. I'm surprised how well its come out given the short focal length and rather large 3.9 arc second pixel scale. I'm really liking this camera.

I love how clean the galaxies look.  Every time I try them, they end up grainy! 👏🏾

Brilliant. I got my first Leo Triplet on the advice of a friend a month ago. Breathtaking what can be imaged by small aperture scopes, well done x10.

I have a question about the colour? The galaxies are very red. As a new comer to imaging why is this so? Not a criticism just a point of reference for newbies like me to learn from.

Thanks Marvin. No idea why the galaxies are that colour. Probably a combination of small aperture scope, large pixel scale and all the light pollution I have to deal with. It also depends on how I stretch the image initially. Usually I have to remove the light pollution first but it can really damage the image. With this I stretched it first in Pixinsight and then done Dynamic Background Extraction. The result was a much smoother better balanced background and it left the galaxies pretty much intact.
