Comet Pons-Brooks passing by C27, 13 January 2024.
Comet starless integrations by subframes in LRGB 60″, 3 x each filter. Star integration from RGB.
C27 and surrounding starless layer in Ha Oiii and Hbeta, 180sec subframes, from 2023 spring-summer several sessions; cfr. https://www.astrobin.com/dqa6po/C/
Comet C/2020 ZTF approaching to NGC300 on 2023 October 16th and 17th.
LRGB data integration by 300sec. subframes with Takahashi FSQ-106ED (106 mm) F3.6 and CMOS camera QHY 600M Pro belonging to Telescopelive network.
This is an attempt of narrowband and wideband data integration of M31 Galaxy, both set recorded on several sessions between 25/05/2023 and 28/11/2023.
Ha and Oiii subframes were recorded at 180 and 300 seconds; LRGB at 60 seconds, everything by William Optics Redcat 51 and ASI1600mm Pro at -20 C about.
Ha narrowband channel integrated R channel
Oiii narrowband channel integrated G and B channels

Galaxy IC342 in LRGB, single session, 2 subframes for channel, 600sec, Officina Stellare ProRC 700 with Proline FLI PL16803 at BIN2, IC Astronomy Observatory of Spain, from Telescopelive network.
A very hard postproduction because of few signal and not so good quality of data, but I really stocked into this processing.

LRGB records for LBN487 and associated cluster NGC7023 by CMOS camera QHY 600M on Takahashi FSQ-106ED from IC Observatory in Spain, Telescopelive network.
Integration I choose as final and best one obtained by RGB master and Luminance master, both star and starless, post producted in Photoshop in separated layer group with local adjustements and blending mode.
Starless section received Luminance integration at 100% opacity in lighten blending mode; stars Luminance at 10%.
RGB version is just a stunning incredible starting point for image development of this amazing stunning nebula complex.

LBN487 and NGC7023 in LRGB, Takahashi FSQ-106EDX4 and Proline CCD FLI PL16083, subframes of 300sec at -25C from IC Astronomical Observatory of Spain, Telescopelive network.
I developed 3 different postproduction: an LRGB one directly developed after LRGB master integration in PixInSight.
I thus proceed to an RGB version and a final LRGB version where L channel, devided in stars and starless masters, I integrated into RGB star and starless layers group in Photoshop with different values, with stars contributing at 10% and starless Luminance at 100%.

According to Karina Voggel and Colleagues investigation of 2022 focused about NGC7727 galaxy in Aquarius, as merging of two distinct galaxies, it was evinced that both host a SMBH – super-massive black hole; cfr.

Original widefield cropped twice
to better focusing about Galaxy.
M33 Galaxy lies among my best favourites targets and IMHO it is very difficult to be photographed.
