great work.

Thank you so much for the great feedback Niko.
Good luck with the new mounting plate. I would (if you have not got one already) also get a ball joint to attach the camera to the plate to allow for better framing of objects. I found that if I just attached the camera straight to the plate then you are limited to whatever angle the mount is at.

There does look to be a blue colour cast over the image. Removing this will bring out the pink nebulosity which you've already captured so well, a lot more. You might also find the blue is being introduced by CA of the 50mm, I find that with my 50mm F/1.4.
Framing is quite nice but I'd like it a little higher so the star cluster under Eta isn't chopped in half.
I often find DSS won't accurately stack images, introducing trailing instead. My solution is to use RegiStar in those cases, the trailing just disappears then. I'm sure other packages might work just as well as RegiStar if you don't have a license, but I'm not sure on free ones. I keep meaning to try Maxim for those situations, never have used it for stacking.
I just read ... 1 x 300 seconds?! 1 frame! nice.

Thank you so much for your thoughts on this Roger
I really appreciate it. I'll see what I can do about that blue/green cast. Being only one frame I might have stretched it a bit too far and introduced the cast somehow. Thanks for the tip re: Registar. I might have to check it out (yet more money
) I agree with you on the framing of the shot. I should have had Eta Carina more in the middle right of frame. I'm also surprissed with how the colour turned out on this. After much experimentation I have worked out the perfect white balance for this camera and my very dark skies. When I point my telescope with an also unmoddified 1000D attached at The Carina Nebula I get a lot of blue.

Thank you very much Bob
I'm glad I can inspire you to try this yourself. I'll see what I can do about that green/blue colour cast....
