From last Monday night I had a good clear sky where I was able to get out for a few hours. I was capturing 400 second exposures for a total of 1 hour 40 minutes of integrated time. Using dithering between shots and just flat frames and bias frames for stack calibration, I spent some time in Photoshop to get this final image. Nothing  too spectacular, but I like these kind of targets with my setup while I am trying to use longer exposures. Seems all the clear skies have a big fat moon in the sky lately…. Guess I will have to just look at the moon!

 

NGC1893

Up at a decent height in the northeast sky by 1:00 AM last night one of my favorite subjects, FIREWORKS!  Well the galaxy at least! 9 subs of 360 seconds each at ISO 1600 for this dim object brings out a crowded field of stars along with the much closer open cluster know as NGC 6939

From Wikipedia:

(Fireworks Galaxy) “Discovered by William Herschel on 9 September 1798, this well-studied galaxy has a diameter of approximately 40,000 light-years, about one-third of the Milky Way’s size, and it contains roughly half the number of stars as the Milky Way. The galaxy is heavily obscured by intersteller matter as it lies quite close to the galactic plane of the Milky Way.” 

“NGC 6939 is located near the border of the constellations Cepheus and Cygnus, at the southwest corner of Cepheus. The open cluster is located  2/3° northwest from the spiral galaxy NGC 6946 (The Fireworks Galaxy), which has visual magnitude 8.8. They appear as two patches of haze with 10×50 binoculars. NGC 6939 can be glimsed with 7×35 binocoluars where as 25×200 binocoluras are required to start resolve the cluster. The cluster can be glimsed with a 4 inch telescope and is resolved at x72 magnification.”
