What is it?
Here attached my NGC281 (“Pacman” Nebula) in Cassiopea. It’s my second picture and attempt to win the APOD. What I like most is the star forming area with its Bok globules so visible in the picture! Open cluster IC1590 in the middle and the multiple star B1 enrich further more this wonderful 1/2 degree sky area. 9500 ly from us and aroun 40ly size. The reason why is also known as the Pacman Nebula looks very clear to middle age man like me but we should may be explain better to young generations!
Place on the earth
I took all the lights into my personal observatory located in Arpino between Lazio and Abruzzo in Italy.
Setup
Telescope: Artesky ARTEC 250 Pro (Newton)
Camera: ToupTek 2600MM
Mount: 10Micron GM2000 HPS II (unguided)
Filters: Optolong 2" Red, Blue, Green ; Optolong 3nm 2’’ H-Alpha, OIII and SII
Accessories: Pegasus Astro Prodigy Microfocuser · WandererAstro WandererBox Pro V3 · ZWO EFW 7 x 2″
Software
Adobe Photoshop · Pleiades Astrophoto PixInsight · Stefan Berg Nighttime Imaging 'N' Astronomy (N.I.N.A. / NINA)
Acquisition
01 - 04 Novembre 2024
Optolong Blue 2": 110×60,″(1h 50′)
Optolong Green 2": 30×60,″(30′)
Optolong H-Alpha 3nm 2": 31×600,″(5h 10′)
Optolong OIII 3nm 2": 28×600,″(4h 40′)
Optolong Red 2": 89×60,″(1h 29′)
Optolong SII 3nm 2": 7×600,″(1h 10′)
Tot: 14h 49′
Image production technique
The picture is the result of a classic Hubble Palette for the Nebula (Luminance + Color) and an RGB combination for the Stars. An HDR has been applied on the Nebula to show better all details hidden by excessive light in the center. All this work has been assessed through Pixinsight and Photoshop software. I also used 3 RC Astro Tools for noise reduction, stars separation and improve definition.
Have a nice day guys!
