Hi James,

Glad you are still getting some practice in, and that you are (I presume) feeling better! :D

I think I still like your second version better, but as to little specifics I can see where perhaps some details are improved, but others maybe degraded a bit compared to v2.

But again, all about seat time and getting a feel for what the image does based on various decisions.

This dataset is still a wee bit too flawed, IMHO, to take it too far though. I think once you get a new set with more limited subexposures and also flats, you'll really start to see what you can come up with.

In the meanwhile, there are of course a number of other datasets available for practice. Some are posted by users here on the forum. There are others in the tutorial section of the main website (also video you can follow along), and well...all over the place. Even HST data. :)

Finally I didn’t drizzle , I bined 50% , I cropped most of problems out of the way for a better wipe, y stretched with a fairly big area of interest.
Y color balanced sampling with a star mask .
Went thru all the modules very carefully, didn’t filter or entropy,
After I had denoised y went back to stars and had another go at dim stars .
Then some LR and here it stays.

Well, slowly does it, …
Can’t wait to go out and get more data .

Thanks .
