Another year and my gaze turns to the lovely Pleiades cluster. This is hard for me to image because of the very bright stars and the diffraction spikes and the associated “star” artifacts. I lowered my sub exposure time to 120 seconds but next time I should go even lower. More subs is a good thing especially when dithering like I am. There is 1 hour 50 minutes here, or 55 exposures combined here.
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!
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
(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.”
Sometimes it’s just about the stars. The Spiral Cluster is an “open cluster” said to be just over 1600 light years away. Can’t say for sure because I have not been there myself, but I hear it’s a decent neighborhood.
Single frame of the Rose Cluster. Do you see a rose structure? I hope I can do some more with this target soon.
A nice dense cluster.
