I think it is really only your star shapes (and I assume the work you do on'em to fix'em) that are holding back your results from being corkers  I think you have explained before but what's going on here exactly?
Not that it matters as they are still good images worthy of display

Thanks for your input Mike!
Stars always seem to be my nemesis!
I've supplied a single sub to show what I'm usually dealing with.
The stars are blocky and I think it's to do with pushing the limits with weight on Heq Pro 5 mount, it's actually guiding quite well with PHD showing the Osc index 0.3 and RMS 0.12 or lower, with guiding duration set to 1.5 to 2 seconds.
But the extra weight of the cooler box and counter balancing creates more torque.
I know when I run with out the cooler I get better star shapes.
Used have flexure but that's pretty well fixed, only minor deflection depending where the scope is pointing.
As far as processing goes, I usually do basic levels photo shop- select magic wand - select a suitable star - then similar - Select modify expand 5 to 7 pixels.
I then use filter Gaussian blur 1.5 to 1.7 pixels - filter other minimum one pixel then filter noise median one pixel.
This usually helps with the star shapes and I might do it several times during processing to try and keep the stars under control.
Ill do a repro on IC 2177 and see if I can fix those stars.
