An emission nebula in Auriga. Taken with an RC 8 telescope unguided at 1600 mm or f/8, QSI 683 mono CCD camera using MyT mount and protrack. Exposure times 240 second each subframe, Lum 5 hr RGB 1.5 hrs each
1795 widely known as the fish head nebula is a bright emission nebula of about 70 light-years across with glowing gas and dark lanes of obscuring dust, located just over 6,000 light-years away from Earth in the northern constellation of Cassiopeia.
Natural colors shown in image 1, Image 2 is done mapping Sulfur to red, Hydrogen to green and Oxygen to blue. Taken using 8 inch RC telescope unguided MyT mount QSI 683 mono CCD
The flame nebula NGC 2024, an emission nebula in Orion constellation. Imaged using 8 inch RC telescope unguided at f/8 (1600 mm) using QSI 683 mono CCD, MyT mount. Exposure times 5 hours Ha, 5 hours Lum 2 hours RGB
An area in Cygnus near NGC 6910. Dark nebula colorful stars and lots of hydrogen gas in my opinion makes one hell of a view. Imaged using RC 8@ f/8 unguided, QSI 683 camera, MyT mount
NGC 1333 a reflection nebula in Perseus surrounded by the Perseus molecular cloud. Image contains dark nebula as well as 5 Herbig-Haro objects. Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometres per second. Imaged using 8 inch RC telescope unguided @ f/8 (1600mm), QSI 683 mono CCD, MyT mount. Total exposure time is 20 hours.
A bipolar planetary nebula in the constellation Perseus. Imaged using 8 inch RC telescope unguided @ f/8 1600 mm, QSI 683 mono camera, MyT mount. Total exposure time is 15 hours.
NGC 6910 an open cluster located in constellation Cygnus.
Imaged using RC8 telescope unguided @ f/8 1600 mm, QSI683 camera, MyT mount
WR 134 variable Wolf-Rayet star located in Cygnus constellation approx 6000 light years distant from earth. Imaged using 8 inch RC telescope @ f/8 or 1600 mm unguided using MyT mount. Exposure times are 30 x 900 sec Hydrogen alpha(red), 30 x 900sec Oxygen 3(blue) Luminance 70x 240 sec RGB 25 x 240 sec each channel. The oxygen channel(blue) does show a complete circular shell though at 7 hours of time the signal is still very weak on much of the sphere.
Tulip Nebula so named for the flowerlike appearance, it is a hydrogen emission nebula. Sharpless101 is located in Cygnus constellation approx 6000 light years distant. Imaged using RC 8 telescope@ f/8 1600mm unguided, MyT mount, QSI 683 camera. Exposure times were Sulfur, hydrogen and Oxygen 900 sec each x 20(5 hrs each channel), LRGB 480 seconds x24or 3.2 hours per channel. total of 27 hours exposure. I included a starless HA image, without stars to distract the nebula is more visible.
Crowded star field and a couple dark nebula, there is a hint of some Ha right center of image though I didn’t chase after it. Very minimal processing just some noise reduction. Taken with 8 inch RC @ f/8 unguided using protrack and MyT mount Lum is 16x 240 seconds RGB is 10 x 240 each channel
