Highly detailed astrophotograph of the M81 Group captured in RGB and H-alpha (RGBHA), showcasing over 130 hours of total exposure time — 85 hours in broadband and 45 hours using a duo narrowband filter.
At the center is the majestic spiral galaxy Messier 81 (Bode’s Galaxy), glowing with a bright yellowish core and sharply defined, bluish spiral arms. The dust lanes are speckled with magenta regions (HA) indicating star formation. To the lower left lies Messier 82 (the Cigar Galaxy), appearing elongated with a vibrant magenta-red core due to intense hydrogen-alpha emission. Below and to the right of M81 is NGC 3077, a distorted dwarf galaxy with a pinkish hue.
The entire field is richly filled with faint galactic cirrus — wispy, smoke-like structures of dust and gas known as Integrated Flux Nebula (IFN), subtly illuminated by the collective light of the Milky Way. These ghostly veils drift across the frame, enhanced by the long integration time and narrowband sensitivity, giving the image a sense of depth and ethereal motion. Background stars vary in size and color, scattered across a black canvas peppered with additional distant galaxies and soft glow from hydrogen emission regions, all captured in extraordinary clarity.
New image! Desperately tried to get to 100 hours broadband but I'm quickly running out of actual night skies here in the UK and the moon isn't helping. Think this is finished for this year! 85 hours BB and 45 hours NB. Description in the alt text. #astronomy #astrophotography #space #fyp #askar #zwo
