Hi, Yesterday I finished processing my latest image of the Flaming Star and Tadpoles nebulae.  I used the Optolong L-eNhance filter and for RGB stars just a UV/IR Cut. I then made a HOO palette (H=R, O=(G+B)/2) and processed my image with my usual workflow with NarrowbandNormalization set on Mode 2. On the final image I was able to see a little teal-ish smudge (I think an Oiii emission) on the top-right.   Have you already seen it in other images or is this just an artifact? |

It looks bona fide but you should check with Vizier/Aladin at the object's location to see what's there. At first glance it seems to match GN 5.11.2 but you should really check it online.

That's a reflection nebula. Since your filter has a wider band pass, you're picking it up. Don't remember the name, but it's in the current data set I'm working on

Here's a glance at it from my LRGB data. It's pretty prominent, but my framing was a bit too tight to really get all of the reflection. Some nice brown dust in there however.   |
