If I used my 40D I would get this view.

Which is pretty much what I cropped. and would exclude the outer rings,

You would have very little wiggle room for cropping stacking artifacts

Not if I got a shorter focal length scope like the 130.

So far in two nights I have got 4 reasonable images,  photo lenses I can get up to 300mm with 1.4x converter or that setup on the 40D about 450nn but the ef 70-210 isn't a great lens at this sort of work, though.

I understand about cropping focal lengths ect, I will just have to practice,  and find what works for me.

On top of that been messing with photoshop for nearly 25 years.

That's a perfect choice for galaxy season and the cleanest Alnitak I've ever seen:)

Great shots. Cheers.

 

I quite like Alnitak  in it. what interests me are the diffraction colours in the diffraction spike.
