NGC 4372 Golden GC with Doodad & M104

[Tamtarn]

Two great nights out here so we had two great sessions. Still have 2 other images to process yet.

NGC 4372 GC in Musca One of our favourite GC's at the end of the Dark Doodad. It's in a rich starfield of yellow stars in a dusty area in Musca which accounts for the small number of hot blue stars. There's quite a few other dark troughs here and there. Unusual little trails of stars in the cluster forming patterns.

M104 Sombrero Galaxy Only two subs taken last night as we ended our earlier session on another DSO. The moon had risen and the wind had been gusty all night so we gave it a try just to end the session.

Lovely work.. I love globs, and your Sombrero is amazing. Better than the one in Stellarium that's for sure Love the detail. I'm definitely getting out tonight.

Very nice Barb and Dave!
Nice color balance and nice and round stars.
I can`t belief how smooth those images look for only 2 or 3 subs!
You must be lovin that 40D
cheers Gary

Fascinating star patterns , plus the nebulous shading in the background sugests some intersting physics in that glob area.

The sombrero is so smooth for only 2 shots........ i know the sky in the yarra valley is superb with good clarity, low light pollution (gee wished i lived there) but youve done a lovely job with that image.

love the star colours

cheers Alchemy

Hope the cloud keeps low and we'll be out there too

Thanks Gary the 40D is a beauty A lot less processing needed as the subs are very clean.

The area around this glob is really interesting and the star patterns within the glob are a feature.

YV not bad these past few nights eh

Thanks for the favourable comments

Very impressive guys. I'll give the sombrero a go tonight on the back of your work

You guys are doing some excellent imaging lately.

I like the framing of M104 - not centred and appears at an angle = looks like a distant UFO and gives the image some depth, not bad for just 2 X 7min subs either

The Musca glob is also one of my favourite globs because of that nice bright blue star next to it and the group of yellow and blue stars nearby.

Wonderful images guys, that 40D is certainly working a treat for you.

Cheers

Nice images Barb and David, I am almost tempted to try imaging myself. I did a magnitude estimate on 4372 a while back because I think the published values are wrong. http://www.iceinspace.com.au/forum/s...highlight=4372
This is the first description of Dunlop 67 = NGC4372 "A star of the 6th magnitude, with a beautiful well-defined milky ray proceeding from it south following; the ray is conical, and the star appears in the point of the cone, and the broad or south following extremity is circular, or rounded off. The ray is about 7' in length, and nearly 2' in breadth at the broadest part, near the southern extremity. With the sweeping power this appears like a star with a very faint milky ray south following, the ray gradually spreading in breadth from the star, and rounded off at the broader end. But with a higher power it is not a star with a ray, but a very faint nebula, and the star is not involved or connected with it: I should call it a very faint, nebula of a long oval shape, the smaller end towards the star; this is easily resolvable into extremely minute points or stars, but I cannot discover the slightest indications of attraction or condensation towards any part of it. I certainly had not the least suspicion of this object being resolvable when I discovered it with the sweeping power, nor even when I examined it a second time; it is a beautiful object, of a uniform faint light." James Dunlop, Parramatta, 1826

Mike we'll have to do more subs of Sombrero soon it seemed to come up pretting well with just the two. We appreciate your positive comments

Glen we would agree with you on this lovely glob it seems dimmer than first described by Dunlop.
