Rosette Nebula

[Sterrenland]

My first chance to get the scope out in 2023...the weather just hasn't allowed any imaging since November.

Decided to capture the Rosette Nebula/open cluster NGC2244 etc. I managed 3 hours of data despite the guiding figures not being brilliant (between 0.7 & 2.3! ) ...so don't always obsess too much about the numbers! My first proper deep sky image since moving into the town (Bortle 5).

Wonderful capture!

Yep, v nice! I try not to watch the guiding  figures as I might try and do something about them! lol

Lovely image. How do you get your stars so sharp?  Mine always seem to bloat.

Hi Graeme...I separate the stars and background after my initial crop, background neutralisation, ABE/DBE, noise reduction. As far as processing the stars I just adjust the saturation and then use MorphologicalTransformation in PI to reduce the star size (a couple of mild 30% Erosion passes usually does it). Adjusting the star curves can also sharpen them a bit I think. I always think my stars aren't sharp enough and are not saturated properly!
