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
Just our moon in HA 10 x 0.01 seconds @ f/8 1600 mm
IC 2574 Wiki has this as a dwarf spiral, the spiral not very clear. A member of the M 81 group. I didnt spend anytime getting Ha data was a mistake it would add quite a bit to the image. Honestly I chose this target because of the Abell cluster in the FOV. I wanted to see what if anything I could get. My scope is clearly to small to capture much. Abell 1005 is in the upper right of image, according to the info I found its in the “richness group” of #2 which has 80-129 galaxies.
ARP 283 I cannot find a distance on the internet. This is a pretty small target about 2.5 by 2.5 arc minutes.(The angular size of full moon is 31 arc minutes)This crop image is approx 8×8 arc mins. I didn’t spend much time on this, as I quickly saw I wasn’t going to get any fine details. This is result of 4 hours LRGB using 8 inch RC @f/8 on MyT mount unguided
NGC 660 – Wikipedia
is a peculiar and unique polar-ring galaxy located approximately 45 million light years from Earth in the Pisces constellation. It is the only such galaxy having, as its host, a “late-type lenticular galaxy”.
Imaged using RC8 telescope @f/8 unguided , QSI 683 mono camera, SB MyT mount. 120 x 480 seconds Lum, 22 x 240 each channel RGB
Emission nebula in Cassiopeia approx 7500 light years distant. Imaged using 8 inch RC telescope @ f/8 unguided using Protrack, QSI 683 mono camera, MyT mount. Exposure times RGB 20 x 240 seconds each channel, Lum 40 x 480 seconds, Hydrogen Alpha 29×900 seconds
Vdb 155 is the bluish reflection nebula near center Lynds dark nebula 1216 surrounds it. This area is right next to a popular target the cave nebula. 9 hours spent on this target. 8 inch RC telescope QSI 683 mono camera on a Software Bisque MyT mount unguided using protrack. Lum 480 sec subs RGB 240 sec subs Ha 900 sec subs
Home to approx 100 billion stars, Messier 74 (also known as NGC 628 and Phantom Galaxy) is a spiral galaxy in the constellation Pisces. It is at a distance of about 30 million light-years away from Earth. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy.
Taken with 8 inch RC telescope @ f/8 using QSI 683 mono cooled ccd. MyT mount unguided using protrack. Exposure times RGB 240 seconds per sub, 34 subs per channel. Lum- 480 seconds x 84
A diffuse hydrogen nebula with some surrounding dark nebula. I personally don’t see how it got he cave nebula name. Area has active star formation approx 2400 light years distant in constellation Cepheus.
8 inch RC telescope, QSI 683 mono CCD camera atop a SB MyT mount unguided using protrack. 9 hours total exposure time.
Portion of veil nebula NGC 6992 shown first in narrowband Sulfur is red Hydrogen is green Oxygen is blue (SHO) nebula is much easier to visualize using narrowband compared to second image same target using “natural colors LRGB. While LRGB is “pretty” the stars distract the eye from the nebula. NB image is 24 x 900 each channel -SHO. LRGB image is mostly time spent on Lum( 6hours) RGB is only 2 hrs each channel. Taken using 8 inch RC telescope @ f/8 or 1600 mm
