Last night, apart from imaging Globs and Opens with the Toucam, I did an IR filter comparison test.
I imaged Trifid, Eagle, and NGC4945 with the IR Filter, then removed the filter and imaged them again.
The below comparisons all had exactly the same settings during capture. Both Trifids have matching settings, both Eagles match etc.
I have not processed any of these images so you can see how they look raw. They come warts and all. Well . . . hot pixels and all.
Both ways have their benefits. Filtered gives far better stars and background, but Unfiltered gives better Nebula and Galaxy.
Make what you want from this comparison test. I just thought I'd share the results.
1. Trifid
2. Eagle
3. NGC4945
