You're doing well Martin. Interesting how we seem to focus on certain types of objects for a while - I haven't done glob's or galaxies for ages (smc excepted).

Thanks Tony appreciate it
When the moons +60% I only image clusters in Bortle 8 Sydney skies
I donít use filters so Nebulas and galaxies have to wait for the dark
Down at my dark site ( Bortle 3/4 ) I image everything with my 8Ē newt , moon or no moon
Going down in a weeks time ( hopefully)

Great image of this cluster. Love the star colours. The 6 inch is such a good all-rounder. You should get some good images next week up at your dark site away from the Sydney glow.
Cheers
Andy

Beautiful work Martin. The star colour is amazing considering that is was imaged during a full moon.

Thanks Lost in Space
I think doing all the little things right eventually shows up in your images
Iím pretty anal with clean mirrors, collimation, DSLR placement in focuser ( I use some Teflon tape to reduce the slop before tightening up the thumb screws), levelling Mount , mount balancing , framing and focus ( I donít just rely on FWHM , I take multiple 30 second test exposures zoomed on a small star in the target field and get the tightest visual focus I can before imaging )
My processing software Startools does a great job, Iíve been using it for 18 months and still learning. It may not be that popular but I enjoy the results and itís particularly good at reducing or eliminating gradients and noise etc

Thanks again
