M2 Globular Cluster under a Full Moon

I’m always testing and exploring ways to produce a reasonable image under adverse conditions and this image is no different
Captured M2 globular cluster last night under the glare of a full moon, with M2 descending low in the northwestern sky with intermittent high cloud and smoke haze present plus Sydney Bortle 8 skyglow
45 x 60 sec guided subs ( only salvaged 20 subs worth keeping, some subs had a band of reddish haze wiped across the middle or corners )
20 x darks
6” f6 Bintel newt on a HEQ5 mount
Canon 600 D with Baader coma corrector
PHD2 guiding at 1.70 to 2.00 arc sec error ( horrible guiding due to conditions , had to find a new guide star every 15 minutes as they became SAT )Big Zig Zag DEC and RA so tried to dampen by increasing min mo and adjusting aggressiveness etc.. fighting the seeing ( could only see 4 or 5 stars in the sky above )
Stacked in DSS
Processed in Startools ( what incredible software for noise and gradient removal / reduction )
Core is a little blown out but considering the ridiculous conditions for imaging I’m satisfied I got a result at all

Thanks for looking , comments welcome

I admire your doggedness Martin , you've turned out a very decent result in spite of the conditions. Well done . The Moon is a hazy golden blob up here tonight due to smoke & thin cloud cover,
I put the scope out earlier in hope & took it back inside a little while ago defeated. Such is the nature of our pursuit.
Cheers,
Tony
