Astro: Sh2-127/LBN 436

Sh2-127/LBN 436 is an emission nebula in northern Cygnus not far north
of M39. Galaxy map has this to say about it: "Radio analysis reveals
that Sh 2-127 consists of two distinct components - a larger weaker and
more diffuse source (WB89 85A) to the northeast, consistent with
ionisation by an O7 class star, and a stronger but smaller source to the
southwest (WB89 85B), consistent with ionisation by an O8.5 class star.
(However, it is also possible that both components are ionised by a
single star.) Both components are located near the northwestern edge of
a molecular cloud and are embedded in the molecular gas."
There is a bright region around a tight group of 3 stars at the south
end. Is this the smaller, brighter region? The red color is stronger
here as well. Galaxy map puts it at 9600 parsecs or about 31,000 light
years away. That puts it on the nearly on the other side of our galaxy.
This is normally considered a very dusty region. I'm surprised we can
see that far across the plane of our galaxy. That would be one super
bright nebula if you could see it at the distance of say the Orion Nebula.

English have a funny way of spelling Ionize.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

you keep digging up the most interesting tiny nebulae Rick

I wish I had time to image all the little buggers you have turned up!

that's cool

I'll second that! Nice one, Rick.

Very good - I've not enough apperature to get anything on this one in
a reasonable time.
