I have been photographing eta carina because it is relatively bright and I am able to use my unmodified mirrorless camera without a cls filter in my suburban backyard. I like this combination because it gives me a colour profile that I like. My question is are the stars of an acceptable shape given my tracking is not ideal?

Nice one Kanga.

The 3rd star on the bottom right up 10 is a little wonky, but otherwise it's a great image ;)

Star are ok, imho. What scope are you using? And if anything, the focus is a little off, but it could just be the low quality of the big you uploaded, a bit fuzzy.

Nice effort Kanga.

With such a wide field in such a star dense region , star irregularities can be quite hard to see. From what I can see the bottom left seems to be trailing. It’s the only corner I can see it in though so I wouldn’t suggest tracking is the issue there. It’s more likely to be a tilt issue.

A great effort though. Well done

Hi Ryan,
It indeed may be tilt -since I damaged my mount and had to flatten it by hand (& hammer). Also I do not think my flattener covers a full (35mm) frame camera.

Hi Glen,
I used an 80ed doublet 560mm with 1x field flattener.

It looks like you have a bit of tilt towards the bottom left. You could always crop it a little bit there is plenty of interesting stuff that would be left in the field of view.
Great image and the colors are fantastic.

Glad you like the colours. I will crop it a bit more.

Hi Glen,
I think the "fuzziness" you see is the luminosity layer I added. For your info. I have attached an image without the luminosity layer.

Much clearer, imho. Thanks.
