So theres no reason to touch the collimation just leave it like it is 

The centre circles doesnt seem to be centre tho

Is this good or bad

My collimation looks spot on though

What it is is that i collimated my scope because one of the kids knocked it and before the comas wernt really noticable but after collimating they are more noticable... Thats what i dont understand 

I use a nikon d3500...... What hardware 

Expensive 133 pounds.. Wow

Thanks

Just wondering if i adjusted my primary mirror up or down would this reducing the comas in my images

Now you've lost me. How can those be just your flats? Or is this the light stack without darks & bias frames?

Anyway, if you load all your subs into a shared dropbox/google directory, I can run them through PixInsight.

Sorry thats just my lights stacked
