Title: Help with M13
Post by: vballrican on 2019 May 31 11:35:15
Hello everyone, i'm new to PI and astrophotography in general.. stuck on what to do after stacking and cropping.. I have tried ABE, DBE, etc.. but nothing seems right to me.  Any help/advice is helpful on the next steps..

PS: This if with just a Master Dark applied to the 50 lights.. no flats or bias.. please be gentle...

Thanks.

Hello and welcome!

Have a look at the "PixInsight Fundamentals" video from Adam Block; https://www.adamblockstudios.com/categories/Free_Content (https://www.adamblockstudios.com/categories/Free_Content)

There you will find some great tips on using DBE and symmetries to reduce those nasty vignetting rings!

Thanks.  Out of the many videos i've watched, i had not seen that one.  Makes good sense to me (too bad it's so expensive to join).  Thanks.

Hi.
You'll slowly learn how to work.
He's still working on the acquisition, to be a better focus.
The picture has noise, and I put a little processing to see what it looks like.
Find tutorials How to proceed, there are many.
