For such a bright globular cluster can I suggest that 1 hour of integration at same exposure lengths ( say 30 sec ) and ISO is plenty as your image scale is around 1.7 arc sec per pixel
In Startools, do you use Auto develop for your first stretch and final stretch or develop ? Develop tends to bloat your stars and brighten your background whereas with Auto develop you have more control

Hi Martin,
All good info, thankyou. I had not imaged a globular cluster before so, wasn't sure what would work (or not).
Still very much feeliing my way with Startools, I did use Auto develop but, didn't play with any of the controls as I am still trying to understand what they actually do... possibly a little impatient to get a result & perhaps need to take some more time & gain a better understanding of what I am doing I think.
I still have the raw data & stack so, can reprocess the 30 sec data separately, re stack & reprocess to see if I can improve the result. The beauty of digital imaging...
I take my hat off to those guys that used to do this stuff with film, I have absolutely no idea how they got the images they did, I honestly don't...
Cheers
