The Owl Nebula

One night on the Owl Nebula. Unfortunately I again forgot to plug in my dew heater, but this time I was lucky and there was a only a very mild dew, the majority of subframes were unaffected. Other than that this was a standard nebula workflow. I used Graxpert for the background extraction. PixInsight has released a new database for the mult-scale tool, so I will give that a try after I have a chance to download the new database. This new database is supposed to be better able to handle dual narrowband filters, such as the Optolong L-eNhance that I used in aquiring this data.

Hello,

I’m Mike

I hope you’ll join me as I explore the amazing universe of astrophotography. This hobby can seem overwhelming at first, but it I find it to be perspective changing and inspiring.

NGC 1499, the California Nebula. This is the first image that I’ve completed with the two sequence dual narrowband filter. I used the DB-Xtract PixInsight plugin to separate the Ha, SII, and OIII channels and then processed with a narrowband workflow. First Quarter Moon from 12/27 Interstellar Comet 3I/Atlas captured November 28, 2025 Getting started on the California Nebula (NGC 1499)…still have to add in the SII data. Had some spare time waiting for other targets to rise, so I returned to Andromeda, about 7 hours total captured over 3 nights in late November. Last full moon of 2025.... 98.6% moon from a few hours ago Messier 45, or the Pleiades, is one of the most recognizable asterisms in the early winter sky. It is a star cluster of nearly 1000 stars located at a relatively close 445 light years from earth. It contains young stars which give the blue color. Thanksgiving moon…from 11/27. 47.1% Illuminated.
