NGC 7814 - The Little Sombrero
Pegasus
RA 00 03 15.1
DEC 16 08 45
Type: Galaxy
Class: SA(s)ab:sp
Size: 6.3' x 2.2'
Magnitude: 10.6
This week's OOTW is yet another William Herschel discovery from 1784. Lying approximately 40M light years away towards the Great Square of Pegasus, NGC7814; or otherwise known as the Little Sombrero, is very similar in appearance to its 'big brother' M104. And why not? Its overall shape and size is nearly identical to M104, but the fact that NGC7814 is approximately 13Mly further than M104 it appears much smaller to us.
A non barred spiral, NGC7814 is very nearly edge on and has a rather thin dustlane that tends to exhibit a bend, or warpage, to it very possibly the result of interactions with nearby galaxies. Many observers have noted fans that extend from either end of the galaxy's disk. The entire disk is enveloped in a halo that is rather bright surrounding a stellar nucleus. Reports online have shown that the overall glow and shape of NGC7814 is visible to some observers, under the right conditions, in scopes down to 100mm. But to see the dissecting dustlane, scopes upwards of 18" and higher power is what you may most likely need.
Here is my most recent observation from two years ago outside Dixon Il using my 25" under SQM 21.38 skies. Sadly, I make no mention of other powers nor whether I was using direct or averted vision during this observation.
13SEP13 NGC 7814 Bright diffuse glow extending NW - SE. Dustlane is most evident at 351x but still remains extremely thin tho dark. So much like M104.
So there you have it!! If you like M104 during the northern hemispheres spring, be sure to check out our autumn Sombrero. I think you'll be surprised just how much it really does look like its namesake!
And as always,
"Give it a go and let us know!"
