The open star cluster M39 in the constellation Cygnus. An unguided image taken last night over Monticello, NY through a Canon 400mm f/5.6 L lens using a Canon 7D MKII dslr camera on a Celestron AVX mount. Thirty 30 second images, eight dark frames, and fifteen bias frames were stacked using DeepSkyStacker, then enhanced with Adobe Lightroom and Photoshop Elements.
Comet Lovejoy looking spectacular for Xmas now with a nice bright tail.
I was surprised to see the small horizontal fuzzy blur under the comet a distant Dwarf Galaxy NGC2188 32.5 Million Light Years away and very dim at Magnitude 12. Making it the dimmest most distant object I have ever photographed!

This is just a small part of the nebula. I would have to do a pretty large mosaic to incorporate it all.
NGC7000 is an emission nebula in the Northern constellation Cygnus. At 1,700 light years away and about 100 light years across, it's a fair sized nebula.

Photographing the Milky Way is my Muse. I keep going back to it seeing if I can approach it from another perspective. It's intensely beautiful. If you've never seen it, then you owe yourself an opportunity to go away from the city or town and out to a rural area. Even a 20 minute drive outside of the city limits will take you to a dark enough sky to see the general shape of the bright Cygnus region. This was taken the morning of August 12 during the recent Perseid meteor shower.
A view of the Andromeda Galaxy in the constellation of the same name captured in a stack of ninety-one images that were exposed for 10 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This photo also shows Andromeda's two satellite galaxies, M32 and M110 (see image notes for the locations, M110 is the small elliptical galaxy slightly below center).

This extent contains eleven Messier objects (M 58, 84, 86-91, 98-100) and many other galaxies. Markarian's Chain is the string of galaxies in the center. My favorite is the Coma Pinwheel Galaxy (M 99) in the center of the upper right quadrant, with its interesting coma shape.

My Nikon D5000 have a serious issue with its sensor. On the right corner and top of the image we can see it failure. A region of the sensor which does have a lack of sensitivity.
First I though it was a "flat frame issue", but it's not. Darks and bias doesn't help.
Only after a carefully processing I'm "ok" in posting this picture. But my Nikon D5000 is old, and I'm not happy to say that it needs to retire.

I uploaded a version of this a month or so back that was supposed to be a combination of this year's data and last year's. Turned out it wasn't - what I got out of DSS was exactly last years data - it completely ignored this year's. DSS playing silly buggers.
This, on the other hand, is the combined data - 2 hours 23 minutes of 60 second subs. This is about three quarter frame, and rotated to provide a different angle - change is as good as a rest. Nice and small and cute :)

NGC 2022 is a planetary nebula in the constellation of Orion, located at a distance of 8210 light-years from the Sun.
NGC 2022 is a vast orb of gas in space, cast off by an aging star. The star is visible in the orb's center, shining through the gases it formerly held onto for most of its stellar life. When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow. This type of object is called, somewhat confusingly, a planetary nebula, though it has nothing to do with planets. The name derives from the rounded, planet-like appearance of these objects in early telescopes. (REF: science.nasa.gov/missions/hubble/hubbles-portrait-of-star...)

Like the Horsehead Nebula, this is my third go-around for the Orion Nebula. The first time I imaged the Orion Nebula was back in 2008 with a Rebel XT DSLR camera. For this picture, a series of short and long exposures were required to see all aspects of the nebula.

I found an empty piece of plastic the other day, on which I had no hesitation in slapping a modded Canon 500D, purchased at a very reasonable price from James Stannard here. There then followed a bit of a learning curve - having been used to a Nikon - which has taken up the best part of two weeks. But I got there in the end :)
This is another collaboration with my good friend Dave Williams from the northern wastelands, who generously donated large portions of Ha, used as luminance.
I will now spend some time trying to breathe life into my Nikon D70 so that I can inflict some considerable pain on the thing, before I eventually kill it - slowly.... :)

This is one of the most beautiful and distinctive nebulae in our galactic neighbourhood.
The eye-catching Bubble Nebula is designated as NGC 7635, Sharpless 162 and Caldwell 11 and lies close to the direction of the open cluster Messier 52.
It is 7 light-years across – about 1.5 times the distance from our Sun to its nearest star, Alpha Centauri and resides 7100 light years from Earth in north-western Cassiopeia close to the border with Cepheus.
The 8.7 magnitude seething star forming this nebula (BD+60°2522) is 45 times more massive than our Sun. Gas on the star gets so hot that it escapes away into space as a stellar wind moving at almost 7 million km/h.
As the surface of the bubble's shell expands outward, it collides with dense regions of cold gas on one side of the bubble. This asymmetry makes the star appear dramatically off-center from the bubble, with its location in the 10 o'clock position in this image.
NOTE: This is a pseudo-narrowband image. I tried with post-processing to give the impression of using Ha, OIII and SII filters. The original version shows only red nebulosity (hudrogen). It was really a persistent and painful struggle in Photoshop :)

What a night for testing my new Star Adventurer! 😍
It took me a long time of waiting but finally I got my dream gear, a star tracker!
So, after years of no guided astrophotography... Let the star adventures begin!
And what a good way to start with these two sisters!
So happy for this result, can't wait for next clear sky night!

Took the same image data I used for the full Orion's Sword image and reprocessed it with an AOI around the Orion Nebula, applying a 3x drizzle. Came out pretty well I think! The star trailing is more apparent at this zoom level, but still tolerable. The drizzle algorithm also successfully enhanced edge detail compared to just zooming in a bunch on the larger image.
The main difference of processing it this way was being able to more finely tune the luminance curve and color treatment for this object/region in particular, as not only did I not have to worry about the other regions of the image, but I could also see the fine detail much better!
Interestingly, this image is not particularly inferior to the one I got through a telescope recently. It is much better in some ways in fact!

Camera: ASI178MM - 120 x 30s
Software: Firecapture - PIPP - DeepSkyStacker - PS6
Another test for lucky imaging with ASI178MM not cooled
No dark, no flat, etc...
Well heavens above - two clear nights on the bounce. I'd forgotten how to do this stuff ;)
My first guided image! :) The Crescent Nebula in Cygnus, a mere 5K light years away.
Bought a modded Quickcam Pro4000, with the adaptor to fit it to the SW 9x50 finder scope, from Badgers/Anton on SGL. Then did the EQ5 handset mod using the kit from Shoestring Astronomy, downloaded PHD and voila. Total cost £90 - can't be bad :) Not perfect of course, but then it was never going to be with an EQ5 and rubbish motors. There was some evidence of wispy bits around this, but it looked more like discolouration, so I took it out - probably expecting too much :)
SW 200p/EQ5
Nikon D70 modded, iso 1600, Baader CC and Neodymium filter
40 x 5 mins for a total of 3 hours 20 minutes
Guiding: Quickcam Pro4000/9x50 finderscope, PHD
Stacked in DSS and processed in CS5
I used the software DeepSkyStacker in order to superimpose 30 standard photos + 10 darks + 10 offsets.
On one hand , we can see that the noise has been decreasing and the contrast is higher but on the other hand the star trails have increased and only the center is sharp :-/
That is a black point of this software.
