I reprocessed this and was able to expose a little more of the outer shell.
This is the RGB + 9 hours of H-Alpha, the H-Alpha was used as 100% opacity in the red channel. If the weather and everything else permits I will be shooting OIII and SII soon.

At a distance of about 1,360 light years from Earth, The Dumbell Nebula is also known as Apple Core Nebula and NGC 6853, this planetary nebula lies in the constellation Vulpecula.
In Vulpecula, not far the the west of M27, The Dumbell Nebula, lies a large area of hydrogen emission catalogued as Sh2-86 is located around the open cluster NGC6823.
To the north east (bottom left) is the smaller fainter area of hydrogen Sh2-88, while filamentary structure to the bottom left of the frame can just be seen, which was catalogued in 1976 as Du 27 by R. Dubout-Crillon. Within SH2-86 itself is the small yellowish reflection nebula NGC6820, which is small but visible on this scale.

For the past few weeks, Mark Radice and I have been working on an astronomy sketching collab video, in which we both sketched the same objects but I did mine from photos, he did his at the eyepiece. We then got together to compare notes and have a discussion about sketching in general. The video is now live on my You Tube channel if you're interested in watching it: youtu.be/O8C3R176qm8
This sketch was copied from a photo taken with the Faulkes 2m telescope which I stacked and processed myself. I used a white pastel pencil and Posca acrylic paint pen for the stars, then the nebulosity was added by scrapping pastel dust onto my page and blending with a dry fluffy brush. The timelapse of me creating this sketch will be coming soon!

More commonly known as The Dumbell Nebula. Sometimes as the Apple core or egg timer as well.
M27 is a planetary nebula over 1,200 light years away in the constellation of Vulpecula. Discovered by Charles Messier in 1764 it's thought to be the first planetary nebula discovered.
They were given the title planetary nebulae by William Herschel, who thought that these kind of objects looked small and round like a planet.

this little bugger is about 3 1/2 weeks now...so they are now just attempting to walk (clumsily mind you) around the room.
I hiked the Pacific Crest Trail from Leech Lake located at White Pass, Washington first to Deer Lake, then Sand and Pipe Lakes, and finally to Dumbell Lake where I spent the night. Total miles hiked was about 16 (25.7K) including walks around Deer and Dumbell Lakes. Round trip elevation gain and loss is about 2200 feet (3540 K) but the trail is mostly gentle with only a few switchbacks and lots of flat or gentle grade areas. Mosquitoes were tolerable most of the time, but plentiful. Weather was great but slightly warm for hiking. Thankfully at times there was a pleasant breeze that helped keep the mosquitoes at bay. There were very few people on the trail until Friday afternoon when I was hiking back to Leech Lake where I started this trip. Ran into a nice back country ranger who was doing high lake aquatic surveys with emphasis on salamander presence/absence. In addition to the names lakes that I mentioned there are many small ponds. That is why there are so many mosquitoes in that area. I believe that I have hiked all of the PCT in Yakima County. Although I have been to all of the lakes mentioned above I took different routes. There is a much shorter easier route to Dumbell Lake from Dog Lake but why do it the easy way when you can see new landscape? IMG_1894
Update: Made it to Explore!! Okay, yeah I know it doesn't really matter and all that but it's still kind of exciting :)
This is (hopefully) only the first few hours of many for this object. For each of the next few nights I set up I'm going to try and get more data. The Dumbell Nebula has a lot more nebulosity than is shown in this image but it's very faint and difficult to separate from the brightness of the sky - especially where I am in town (lots of light pollution, I can barely see mag 5 on good nights). I'd like to get at least 12 hours but we'll see...
Here's some info from the Wikipedia article on M27:
The Dumbbell Nebula (also known as Messier 27, M 27, or NGC 6853) is a planetary nebula (PN) in the constellation Vulpecula, at a distance of about 1,360 light years.
This object was the first planetary nebula to be discovered; by Charles Messier in 1764. At its brightness of visual magnitude 7.5 and its diameter of about 8 arcminutes, it is easily visible in binoculars, and a popular observing target in amateur telescopes.

I thought I would try incorporating my Astrophysics CCDT67 into the imaging train to increase my FOV and to get a better imaging scale.
I set the spacing to 85mm which would give me the proper .67x reduction.
I am very pleased with the way the stars turned out and at the spacing of 85mm the AT8RC is now operating at f/5.4 with a focal length of 1105mm. My sampling is now at .859 "/pix which is almost perfect for my average seeing of 2.5-3".
Unfortunately the fog rolled in while imaging M27 and only ended up with 8 x 600 sec L bin1.
Most miniature railway locomotives are based on something representing a design or shape to be found on the "Big Railway". The B-BPM named 'Wendy' that ran on the the Whorlton Lido Railway didn't really fit that pattern being a cross between a Super Clayton and the Fell locomotive in body shape. It was built by Coleby-Simkins Engineering Ltd of Melton Mowbray in 1972 and spent many years going round this 750yd long dumbell shaped line at this County Durham tourist attraction. Alas the line appears to have closed after the 2004 summer season and the whole site has become a matter of local controversy.

70005 undergoes maintenance - outside - that wouldn't happen in a depot 'up north'. My daughter impressed by the size of the ships in the terminal, loaded with containers and also showed an interest in the weights / dumbells laid out around the yard. Cool was the response when I told her they were lines of wheels. Presumably four sets of wheels at the back are from 08s.
The other shot looking down the loading area with an unidentified Freightliner class 66 at the head of a train waiting to be loaded with 66419 in the middle of the yard to the right.
Not brilliant as I knocked my scope and may have upset my focusing and tracking. Posting anyway. I did try out the new multi-star guiding function in PHD2 and it looked good. I'll realign the scope etc. tonight and try again...

The Dumbbell Nebula (Messier 27) is a so-called planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years,
A planetary nebula, nothing to do with planets, is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.
All planetary nebulae form at the end of the life of a star of intermediate mass, about 1-8 solar masses. It is expected that the Sun will form a planetary nebula at the end of its life cycle. Once all of the red giant's atmosphere has been dissipated, energetic ultraviolet radiation from the exposed hot luminous core, called a planetary nebula nucleus (P.N.N.), ionizes the ejected material. Absorbed ultraviolet light then energizes the shell of nebulous gas around the central star, causing it to appear as a brightly coloured planetary nebula.
This is a false colour image with the Hydrogen alpha emission line mapped to violet, Sulphur II to orange and Oxygen III to green
I don't know why I wanted this set, I just did, & now I have it. Unfortunately, there's a problem with one set of barbells. The black ones should have a long middle piece & also, the little pieces that keep the weights on are missing. I have emails out to see if I can get a replacement, but I'm not optimistic, & I'm not going to send it back anywhere. Anyway, this is what the 5 sets are:
1. Red dumbbell
2. Blue dumbbell
3. Blue iron array
4. Black barbell
5. Silver barbell

Another topic that I wasn't overly pleased with.lol I wish I had had a better "stick" to poke through the apples. And also I don't think I've ever posted a shot this quick after seeing what the challenge was

Taken on 20th of September 2020 from Rochdale, UK.
30 exposures of 4 minutes each, stacked together with calibration frames in DSS and then processed using StarTools.
Equipment used:
Taken with a Canon 1100D DSLR using an Astronomik CLS CCD EOS APS-C clip filter. Neewer intervalometer to control the exposures. Attached to a Skywatcher Quattro 8" Newtonian reflector sat on a Skywatcher HEQ5 pro mount. The setup was guided with an Altair 50mm guide scope and GPcam AR0130c guide camera.
My entry to the 52 weeks project at:
www.flickr.com/groups/2470421@N22/
This weeks theme is "Out with the old".
Did you make any new years resolutions? I never do, so this is more symbolic for resolutions.
The only resolution I made this year was to take it a little easier with photography. I finished a 365 project on new years eve. It was alot of work but mostly pleasurable.
Shot this photo yesterday and processed and uploaded today because I was too tired yesterday. That would not have happened last year.
Notes: The buildings in the background are part of the school residence with hall attached. Both these buildings were demolished in 1913. The school moved to Burns Rd in 1954, the site is now a Council car park.
“The development of a school at Springwood was largely the result of the railway extension into the Blue Mountains in the mid-1860s. Springwood had but a few farmers, and further settlement required an easier and quicker means of transport, which the railway provided.”
“In the 1870s Springwood was a railway town, mainly comprised of families with railway connections in some way.”
Most children did not attend any school until Springwood Public was built, and the application stated there were 49 children (29 boys and 20 girls) within 3.2 kms of the proposed site, next to Springwood Railway station.
Charles Schowe was appointed teacher and classes began on Monday June 10 in 1878. By the end of the year, there were
54 students enrolled."

This is Pinky and right now it's the tastiest toy ever. I hear it costs 88 cents at Walmart. Not sure what that is, but please go get more - times are tough, need to stock up on toys. And I only have...don't know... just about a hundred of them...

Another Narrowband Hybrid of M27. RGB was replaced using channel swap (except for a small percentage of green channel) with OIII as Blue, OIII as Green and H-Alpha as Red. No SII used in this version. Then I used H-Alpha and OIII as luminance. Finally I used the stars from the RGB image for natural star color.
