Hi,

 

I managed to capture the Rosette Nebula this past week, even though it was pretty close to well lit moon in the night sky.   I'm using a Nikon D750 (not modded) and the Optolong L-Extreme.   Unfortunately with this attempt I had to move my gear before I could take my flat frames and I bumped into something while moving the gear so the flats didn't handle the dust motes.  I was also shooting in my front yard where there are street lights and home lights.   All of that said, I'm pretty happy I was able to capture the nebula with some detail.  I know I'll get a lot more detail when my ASI294MM pro arrives later this week.   This is 26 3 min subs captured at ISO 800 for a total of 78 mins.     This is some of the best FWHM data for me as it was in the 6.0 range.   Not great by other standards, but I'll call it progress.  I processed this in PixInsight using the Mitch's 1 hour complete processing tutorial.   The part of the image that was the most issue is the surrounding background.   It was really red and I ended up doing a CurveTransformation just targeted on that area to try to remove as much as I could.  I'll upload the data here shortly so if anyone wants to work with it, please feel free to do so.   Feedback on areas to work on appreciated.

Stacked files from Pixinsight will be here as soon as they finish uploading.  https://drive.google...NnT?usp=sharing   By the way, when folks post their data is that typically the file set they post?

Downloading your data. The file is huuuuge. There is no point in packing the rejection maps into the file. Only save the integration. There is no point posting the calibration masters because you (hopefully) have already applied them to each single sub.

Here is a quick processing:
