Sun rising on improved processing

Monday dawned clear and bright so we set up the hydrogen-alpha (Ha) solar telescope and recorded some image sequences. Today was a dull and cloudy day so we spent some time learning new processing techniques for our solar imaging and were rewarded with our best shot yet. The processing of choice was Solar Toolbox — a script package developed for use in PixInsight software — just the set of tools we were looking for! We’ve a long way to go but we think this picture shows great progress!

My PixInsight processing comparison between 2021, 2024 and 2025 and some Tools and Methods I use.
I am overwhelmed by the differences of the final results when skill and tools grow.

Pan Marcin był chory
I leżał w łóżeczku
Wystawił więc Seestara,
By coś tam smażył w ogródeczku...
A co widział i wypalił znajdziecie na obrazeczku.

Znaczy na kilku, bo wychodzi na to, że mam 2h materiału (a 3h pracy) a od 8:30 do 16:30 się bawiłem w obróbkę i jest kilka wersji.

Celem miała być mgławica IC 1795[1], czyli Mgławica Rybia Głowa (Fish Head Nebula), ale po małej korekcie, jako cel została uznana gwiazda oznaczona jako HIP 11505.
Obróbkę robiłem za pomocą:
A) aplikacją do obsługi teleskopu Seestar S50
B) Siril 1.2.6+GraXpert
C) PixInsight z różnymi ustawieniami.

1) Obróbka aplikacją do obsługi teleskopu Seestar
2) Siril+GraXpert
3 i 4) PixInshight + GraXpert (2 wersje)

Czuję, że czeka mnie duży wydatek na PI+dodatki.

Over the past few nights, I’ve been running the RedCat with the ASI2600MC exclusively on IC 443, with the Monkey Head Nebula also in the frame. The nebula is processed in HOO (extract) using the APP RGB Combine process, while the stars were handled separately in pure RGB.

Dates: February 16–19, 2025
Sub-frames:
-Altair Ha Oiii DualBand ULTRA 4nm CERTIFIED CMOS Filter 2": 191×300″ (15h 55′) (gain: 100) at -10°C
-Optolong L-Quad Enhance 2": 13×300″ (1h 5′) (gain: 100) at -10°C
Total Integration: 17h

Calibration Frames:
Darks: 20
Flats: 20
Flat Darks: 20
Bias: 30
Processing followed my usual PixInsight flow, but after a NoiseX Light pass, I focused on TGVDenoise in CIE Lab* mode using an inverted lightness mask (see this guide). Final tweaks to the stars and composite were done in Photoshop. Edited on a BenQ in P3 with final checks in sRGB (P3 shows deeper reds, by the way). #astronomy #astrophotography #space #deepspace #pixinsight

Here’s the result so far:

Had a rare clear night yesterday.. well part of it anyway, it was rudely interrupted by a heavy snowfall, but managed to bag 4 hours of exposure for the Flaming Star and Tadpoles Nebulae. First time processing with Pixinsight, I have to say it's quite overwhelming at first but it is quite powerful as a tool. I'm enjoying the generous 45 day free trial for the moment but I'm serously considering buying it. Many thanks to Lukomatico's youtube channel for short and to the point tutorials!
