Can I do "HDR-like" processing techniques with my QHY9 CCD? Just reading Humayun's comments in Marin Pughs widefield thread here and the 2 lots of exposures he captured to make
this great image made me ponder the need to explore the options for multiple exposure lengths in CCD images when time and sky allows. My reasoning:
- Although QHY9 is 16bit for great dynamic range, has relatively small well depth
- 8" Newt sucks in the light and saturates stars in my images pretty quick (particularly with smaller QHY9 well depth)
- Pixinsight now has some very nice HDR tools
- Logically this should be a good way of going deep for nebulosity on DSOs while maintaining star detail and colours
Presumeably there would be a lot more fiddling about proportional to how many HDR "layers" you collect.
Is this something people do too often?
