Pinwheel Galaxy M33

One of the bright members of the Local Group of Galaxies,
and probably the nearest spiral galaxy after the Andromeda system M31.
Lies on the western portion of the constellation Triangulum.
18-22 November 2012.
41 exsposures but 10 minutes each stack in DSS.
Full calibration .
Was very bad "seeing" and fog around my house,
PS
Astronomical " seeing " refers to the blurring and twinkling of astronomical
objects.The Astronomical seeing conditions on a given night at a given location
describe how much the Earth's atmosphere perturbs the images  of stars
as seen through a telescope.
Seeing is one of the biggest problems for -Earth based astronomy.

Double Star Cluster in Perseus

One of the truly classic examples of galactic cluster,
and a wonderfully beautiful object.
Among the all-time favorites for all observers.
21 November 2012. Tiny Ontaro.
12 exsposures x 5 minutes each stack in DSS.
Full calibration/dark files,flat files,bias files apply/
Catalog # NGC 884 and NGC 869 .
PS
Was very bad seeing , mist around my house

Comet 168P

 

"Frozen" comet motion in DSS /deep sky stacker/ .
Not bad !  :)  Roman

Comet 168P- Still , motionless !!!

"Comet staking with motionless stars is very difficult and is close to voodoo that it sometimes works.
 Depends on the SNR/signal to noise ratio/ of the lights /exposures/. Of course high SNR requires long exposures
which means either the stars or comet trail. So it's a combination of comet speed , aperture and focal
 length that determines what the result will be"- Sander DSS.
I tried it but I need "faster" telescope  F-3 or F-4. Like you se all colour data is lost. Roman
No problem in grayscale  : )

Crop at 50% resolution.Telescope location:Tiny Ontario

Comet 168P/Hergenrother 22 Oct.2012

1 hour -20x 3 minutes exposures stacked in DSS. Telescope:10 inch at F-5.

Was very bad seeing and transparency , humidity almost 100% .

Bubble Nebula NGC 7635

Nebula in constellation Cassiopeia.
