Description

Hi All!

After four months of poor skies ( a new record for me), I was able to get out for 5 nights out of seven (9/14/22 - 9/21/22) and it surely felt great to be out again!
This is my second attempt at the Cave Nebula. The first attempt left me with disappointment and I never finished the process. 
This time, I am not happy with the results and I am sure that I will revisit the data again. I probably won't image this target again.
After several days of looking at different versions, I settled on this one which is only slightly modified since the initial stretch. It looked "better" this way.

Thanks for looking!

Title: A More Pleasing Process To Me

Description: I have really struggled with this data to get a decent process.
I really never was satisfied with the original process. Actually, I am not satisfied with this one either!
This is a really tough target (for me) and I would have to dig deep to image it again. However, I am more comfortable with this revision as it looks more "pleasant" to me.
I hope that it looks better to you also, but still not where I would like it to be.
Comments and suggestions welcome!

Title: Sh2-155 The Cave Nebula in Foraxx Palette

Description: Reprocess from original masterlight.
The coloration is really different, but pleasant. Big improvement in details (in my opinion).
Cropped and slight star reduction.
After the initial processing, I was unhappy with the result and just thought that this target was too much for my Bortle 6-7 skies and I really didn't have the clear sky time to do it justice.
I am happy with this version!
Thanks for looking.
