NGC 1491 a bright nebula is Perseus constellation. Image could probably benefit from some more time on it but I moved on. Taken with 8 inch RC telescope, mono camera. LRGB 240 second subs 2 hrs each channel, HA 900 second subs 4 hrs.
Quickie shot of Comet Atlas taken 4/1/2020 with 8 inch RC telescope. 7x 120 seconds each channel LRGB
Colorful with plenty of dark dust bands breaking up the color, home to 400 billion stars. I give you Messier 63, located 27 million light years distant in constellation Canes Venatici. Classified as a flocculent galaxy because spiral arms aren’t visible. I think the spiral structure is obvious however without any clear arms. Taken with 8 inch RC telescope @f/8 unguided using protrack and MyT mount, mono cooled QSI 683 camera. Total exposure 18 hours.
NGC 3079 50 million light years distant in Ursa Major. Large telescopes will show giant “bubbles” coming from area of super massive black hole. There are several other galaxies shown in the field of view. I find the most interesting object the marked quasar toward upper left of center. The 2 bluish objects is actually 1 object gravitationally lensed there is a 417 day delay in any change in brightness between the two objects.
Taken with 8 inch RC telescope @ f/8 unguided using protrack and MyT mount QSI 683 mono camera astrodon filters. Exposure times were 240 seconds each channel LRGB 3 hours each RGB hours Lum.
A barred spiral galaxy 33 million light years distant observable in constellation Leo. Taken with 8 inch RC telescope @ f/8 unguided using MyT mount and protrack, QSI 683 mono camera. Exposure times RGB 240 x 20 each channel, Lum is 88 x 240 seconds.
Sh2-194,193,192 3 small possibly connected nebular areas near the Heart and soul nebula. Not much in the way of structure at least not from my scope. RC8 telescope@ f/8, MyT mount unguided using protrack, QSI83 camera.
12 million light years distant a starburst galaxy in Ursa Major. Imaged using RC 8 telescope at f/8 unguided. LRGB subframes 480 seconds HA 900 seconds total exposure time 12 hours.
Messier 101 a large asymmetrical spiral galaxy, home to around 1 trillion stars twice that of the milky way. “Only” 21 million light years distant in Ursa Major. Taken using RC 8 telescope @ f/8 1600 mm, MyT mount unguided using protrack, QSI 683 mono camera. Lum 480 seconds x 50 , RGB 240 second x 20 each channel, Ha 900 seconds x 12
False color image, Colors mapped Red is Sulfur, Green is Hydrogen, and Blue is Oxygen taken with 8 inch RC telescope. Total exposure time is 14 hours. 15 min sub frames.
NGC 2170 is a reflection nebula in the constellation Monoceros. I had a difficult time with this, the image overall still has a decent amount of noise mostly because I didnt want to destroy some of the really faint details. Every time I look at this I see a fairy flying. RC8 telescope @ f/8 1600mm, MyT mount unguided, QSI 683 mono. Lum 480 x 50, RGB 240 x 30 each channel, HA 900 x 20
