Hi Folks,
last night, OCT 26th, The weather finally cooperated and allowed me to take my 6 inch refractor out to the end of my driveway for an imaging session with the DSI Pro II. Altogether, I actually imaged three different objects, I also re-imaged M-33 and NGC 7332, but I will post those later. NGC 7814 is a spiral galaxy seen edge on and is approximately 40 million light years away, there are a number of small faint galaxies seen in this direction. If you can zoom in on this image you may see some small faint galaxies that shine through its halo NGC 7814 has an interesting research history. This fantastic edge-on spiral galaxy in Pegasus proves to be an interesting object when displayed in the way shown. First, the plane of the galaxy is slightly warped and twisted. NGC 7814 is one of a few bright galaxies that shows this feature in optical wavelengths. Second the number of background galaxies in this direction is impressive. Besides being pretty, these far off beacons have been used by astronomers to try to determine the amount of gas and dust in the halo of NGC 7814. As the light of background galaxies passes through the foreground halo of NGC 7814 it becomes dimmer (redder). Finally, be certain to note the very slight deviation from being truly edge-on. The shot was made with my Celestron C6 RGT f/8 refractor with a 0.5X focal reducer and a minus V filter to reduce the smearing efffects of CA that is inherent with an achromat objective lens design. I took 50-42.4 second subs from my very light polluted driveway and processed them with the Autostar IP software. Dennis |
