CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!
This is my first attempt at capturing a globular cluster at long focal length with my C8 EdgeHD, as well as the first light from the new ZWO ASI533MC Pro under a thin crescent Moon (17% illuminated) and I am pretty impressed with the results! I chose Messier 4 as this is one of the most prominent globular clusters that the southern skies have to offer under the barrage of light pollution from the CBD relative to my location in Sengkang.
In terms of post-processing, I had some difficulties in getting rid of the green bias in the fainter stars in the cluster as a result of the RGGB bayer matrix in colour cameras. I finally resorted to creating a star mask for these faint stars and adjusting the colour balance to my liking of a bluish tint, although their true colours would be closer to red since most stars in a globular cluster are red dwarfs.
