Waning Moon, 26th August 2019

I took 100 subs (1/500th @ ISO800) for this image at the end of quite a long night last night. The seeing had been excellent, but I’m not really happy with the outcome here. I think perhaps the DSLR doesn’t cope very well on images which are mostly black and then a small amount of very bright illumination. Preprocessed with PIPP, 40% stacked in AS!3, wavelets in Registax 6 and PS for the final tinkering.

I think it could be time for a change of technique for full disc lunar imaging. Perhaps switch to my ASI174MM and create mosaics or drop the focal length a little. Then I could use the DSLR for wide field instead. Needs a bit of thinking about.
