Andy, your comment about this image being out of focus and not sharp intrigued me, particularly that you have made similar comments about my images in the past.
Curious, I looked up your images of the same target on Astrobin, one taken with 70mm and the other with 110mm refractor, and made a little side-by-side comparison, without altering your images in the slightest, just aligning all three, with my image taken with 105mm being in the middle. This comparison is purely a result of your repeated comment about lack of sharpness in my images - I will delete the comparison if you feel I breached copyrights.
When looking at star sizes, I think the middle one has the tightest stars, in spite of imaging from humid North Queensland. Do you think that my images appear to be less sharp because I aim at preserving natural structures during data processing?

Hi Suavi,
Maybe it’s a processing choice, maybe it’s because it’s an image of gas & not a hard structure. Then again maybe it’s just me being used to seeing sharpness in day to day professional images!
I’m also a tad paranoid about apparent sharpness due to recent collimation errors in my ‘scopes.
Interesting discussion
Cheers
Andy
Ps: Your Ha stars should of course be sharper & tighter than my RGB ones, taken under LP
