Snoopy 45 hrs

[Placidus]

Here's the one we've been waiting for. NGC 2467. Big image here. (https://photos.smugmug.com/Category/Star-Forming-Regions/i-4FLbdSJ/0/f43c50c7/X5/Snoopy%20Ha%20OIII%20SII%2015%20hrs %20each-X5.jpg)

15 hours per channel in Ha, OIII, SII.

Ten hours per channel in 1 hr subs spread over 2013, 2014, 2016, and 5 more hours per channel in 15 minute subs over this and the previous new moon.

We've mapped the star colours to white. South is up, so you can see Snoopy.

It's only an incremental improvement, but we're quite pleased.

There is precious little SII (red) in this nebula. It has taken 15 hours of exposure to really show it convincingly. It is mostly in the "cross-bones" (Snoopy's bathing cap), the coat-hanger, the "beach ball" (large hollow structure surrounding an open cluster half-way to 6 o'clock) and in a very small, more intense hollow structure surrounding a single bright star in the centre of the image. SII tends to be associated with supernova remnants, and the lack of it suggests that not so very much SNR activity has occurred here as yet.

That looks awesome Mike. Cooking now. :thumbsup::thumbsup::thumbsup:

Awesome :thumbsup:...I can finally see Snoopy too, I didn't have to open your anottated version either, looks just like him :2thumbs:

Well done, a nice 3D look around the area of Snoopy too.

Mike

[Placidus]

Thanks Marc.



Thanks Mike. Glad you saw him too.

Looked up ESO and Wikipedia blurbs. It is indeed a very young star-forming region, or more particularly, several of them on the same line of sight.

Best,

Very nice MnT. I see a man with piercing eyes.

[Atmos]

Very nice M&T :thumbsup:
Without comparing your previous version side by side with this new one it’s difficult to tell the difference. I imagine it would be more significant in the background though.
45 hours is a fair chunk of time ;)

[Placidus]

Ta Geoff. He must be in a quantum superposition with Snoopy.



Thanks Colin.

There's an image using the ESO 2.2 metre scope here (https://www.eso.org/public/images/eso0544a/). You'll need to rotate it 90 degrees to make it match ours. Theirs is superbly better, of course, but much of the fine dust lane tracery in theirs is blurrily visible in our shot too.
