Well, still nice in the amount of signal! Does seem like the details are a bit washed out, did you use another program next to APP?

Thank you Vincent. Yes, I used Photoshop and Light Room in post processing  As you pointed out, this image is still lack in fine details  New version will be taken as soon as the weather allow.

I would advice to go very easy on any noise reduction scripts, I think you have way more detail in here than you think. I would even do without that on the nebula itself, so just on the background. This can be done in something like PI using masks to protect parts of the image. If you're not able to do that, I would just not do it at all. Noise is part of the game anyway. But that's simply my take, just wanted to give a tip. 🙂

Hi, Vincent

Thank you for your advices. I am not able to use PI yet. However, masking out  the nebula in PS before star reduction and noise reduction would protect details of the nebula.

Yes well it could become better with more data for sure, but I clearly see more detail in this second processing of it. If you look at the dust swirls, you can see them more clearly, don't you think? It's always a learning process anyway, part of the fun. 🙂

Yes, it is. I always learn something new every time from this forum.
