ASTRO: NGC7814 From Colorado Springs
I have finally got something to contribute... Not the best conditions but
fun none the less. This galaxy is nearly edge on but a lighter dust lane can be seen in the full size image that I believe is opposite the dark dust... Is the dark dust the disk on the far side of the galaxy? The galactic disk is certainly thin. Full size and info: http://www.wheeland.us/galaxy/ngc7814.htm -- Regards, Doug W. www.photonsfate.com |

Nothing but clouds this lunar cycle This one was a failure for me last year. I couldn't get the dust lane to come out very well. It wasn't much better than that second lane you caught. You show it can be done! I'll have to give it another shot if the weather ever breaks. I found this note at NED: The galaxy is seen nearly, but not quite, edge on. The parallel structure in the dust lanes, appearing as the fainter lanes below the main lane in the print here, shows that we view the thin dust layer from slightly above the plane on the bottom side of the image here, seeing part of the plane in silhouette on the near side (bottom) against the central bulge. Another note: Very bright central bulge: 0.5 arcmin x 0.4 arcmin. Outer bulge: 2.0 arcmin x 1.2 arcmin. Strong, thin (0.1 arcmin) dark lane seen edge-on with secondary layer of dark material. We have a lot of clouds in October but they are starting early this year. Didn't help that I lost a couple nights fighting a dropped out screw in the filter wheel system.

In both the core is rather round rather than flat. Some of the NED notes noted this roundness. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

I guess I did not read that carefully enough when I looked at it. I did not
see the image they refer but I guess it must have had the fainter dust below the dark. In that case, it seems the dark dust is in front of the central area in our line of sight... guess the bright core shines through all that dust quite well.

Great image Doug. There is even detail in the dust band. I don't remember
seeing that in other images, my images only show a featureless thin band. Stefan "Doug W." schrieb im Newsbeitrag . .. I have finally got something to contribute...

Wish it would have been 2.5" sky instead of 3.0", but I'm just happy to have
been able to run the system. Thanks -- Regards, Doug W. www.photonsfate.com "Stefan Lilge" wrote in message ... Great image Doug. There is even detail in the dust band.
