This has to be my cleanest Andromeda to date.Captured in Nova Scotia in August..after 2 1/2 months of working on it..I call it finalized.Every processing step was zoomed in at 100% to make sure the stars weren't taking a hit..I didn't want to over-saturate with color..Complete @ 3 1/2 hours integration time

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!
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.

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 :)

That is a black point of this software.

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...)

I gave my 500mm mirror lens a go with the Sony A7 and a nano.tracker sidereal rate tracking platform tonight.
I went for 15s exposures (at the fixed f/8 aperture) and ISO 6400. In total 37 frames were used for a total exposure time of 9m 15s, along with 19 dark frames.
Images were stacked with DeepSkyStacker and with final processing in Photoshop to remove vignetting.
The Orion nebula is often referred to as a stellar nursery, a place where new stars are being formed out of collapsing gas clouds.

Clustermania :)
A three hour gap in the endless, persistent cloud cover gave me just enough time to do another one of these things. Nebulous stuff takes several sessions under my light polluted skies, and would take months with the weather being as it is, so clusters beckon.
This is M38, aka NGC 1912, aka The Starfish Cluster (don't ask me why), and to the right is NGC 1907. M38 is about 4,200 light years away and is about 25 light years in diameter, similar to that of its more distant neighbour M37. It is about 220 million years old. NGC 1907 is around 4,500 light years from Earth. It contains around 30 stars according to Wiki (looks like more to me) and is over 500 million years old.
This is a closer crop than my previous two cluster efforts, for two reasons: first, the framing was rubbish, and second, the stars at the edges reminded me just how much I need a field flattener!
I'm running out of double clusters to do :)

Had some issues with DSS 3.2.2, but 3.3.3 beta 51 and I got along a lot better. This is my first attempt at stacking RAW images. This is a total of 11 RAW files that represent a total of 6 minutes of integrated exposure time. The Pentax K-5ii was set at ISO 800 for all exposures and these are camera-on-tripod subs, "guided" only by the Pentax O-GPS1 unit stuck in the hot shoe, which moves the camera's sensor to compensate for the turning of the earth. The longest sub-exposure was 45 seconds.

We had several clear nights on the bounce a week or two back, and I spent the time imaging this thing as Cygnus was still getting up above my house a little late. This is just short of 10 hours, but I put it away because I got the feeling it was out of focus when comparing it with the version I did back in 2011 with the 200p. The stars in the cluster don't look quite as tight as I think they should.
Whaddya reckon? Out of focus?
Continuing my collection of Not Comets (Messier objects), this is the hugely exciting M92. On its own it would be a reasonably bright cluster (not from my garden) - but when you're in the same constellation as M13, you tend to pale into insignificance.
Now the core of this was interesting. It seems to be a lot brighter even than the core of M13, and was well saturated at 180 seconds. I did some shorter subs to capture the core (10 seconds in fact) and manually stacked them because DSS just chucked out a grey splodge. Layered in, you can at least see some detail in the centre. This is a wider field of view, just to ring some changes.
Now, what next I wonder? :)
