I've never used drizzle in DSS before, but I thought I'd give it a crack on this as the galaxies are so tiny. Seems to have yielded some improvement, particularly in M66 - the more interesting of the trio.

NGC 2841 is an unbarred spiral galaxy in the northern constellation of Ursa Major. J. L. E. Dreyer, the author of the New General Catalog, described it as, "very bright, large, very much extended 151°, very suddenly much brighter middle equal to 10th magnitude star". Initially thought to be about 30 million light-years distant, a 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined its distance to be approximately 46 million light-years.

The third time I've posted images of this field on Flickr, but this is new data gathered using an EOS 600D modded for astrophotography. I was pleased with the result, although there are 3 flaws:
1. One frame had a diagonal streak, caused I think by a washing line just in front of the scope! You can just see it in the final result. I could have left the frame out of the stack, but I liked the effect!
2. There is a red disk around bright stars (over-exposed on Alnitak), due to out-of-focus infra-red. I've now ordered an IR-cut filter to prevent this.
3. Alnitak has flared over the frame even more than normal - this only affected some frames and I've not got to the bottom of that. I've tried to tone the effect down in the final image.
The exposures were manually, off-axis guided. Sub-exposures registered and stacked using DeepSkyStacker; processed using Canon Photo Professional and Noel Carboni's tools in Abobe Photoshop Elements.

I was excited to capture 30 minutes of imagery of my first comet, C/2017 T2 PANSTARRS, on Thursday, January 30, before clouds moved in.
Since I wasn't sure I'd get anything because of clouds, I didn't bother to drive to my Bortle 3/4 dark site, but instead shot from my Bortle 5 backyard, 60 x 30 seconds. I combined this imagery with some better imagery of the Heart and Soul Nebulae from this past fall (47 x 60 seconds under Bortle 3/4 skies), to create this small mosaic (the Heart and Soul Nebulae turned out a bit ugly from my Bortle 5 backyard). I was impressed with how well Astro Pixel Processor combined the imagery of such differing quality.

The Mythology:
Andromeda, the stunning daughter of king Cepheus. Cassiopeia, her mother, boasted once that she is more beautiful than the Nereids, the nymph-daughters of the sea god Nereus. The queen had to be punished for her arrogance. So Poseidon sent Cetus, a sea monster, in order to ravage the coast of her kingdom Aethiopia. Apollo's oracle to the desperate king Cepheus was to sacrifice his daughter. Andromeda was chained to a rock and waited to be devoured by the sea monster. But her fate was a romantic one. The Greek Hero Perseus killed the sea monster and finally married her.
Their descendants ruled the kingdom of Mycenae in full glory.
After her death, the goddess Athena placed Andromeda on the sky as a constellation, next to her beloved husband Perseus and her mother Cassiopeia.
The Astronomy:
The gigantic spiral galaxy of Andromeda, designated as M31 or NGC 224, lies approximately 2.5 million light-years from Earth and acquired its name from the area of the sky in which it is located, the constellation of Andromeda.
M31 contains more than one trillion stars while the galaxy's stellar disk extends for as many as 220,000 light years.
Excluding the Large and Small Magellanic Clouds - which can’t be seen from northerly latitudes - the Andromeda galaxy is the most distant thing visible to the unaided eye (though this observation requires dark skies and experienced naked eyes).
It wasn’t until the 20th century that astronomers were able to resolve the Andromeda spiral nebula into individual stars. This discovery lead to a controversy about whether the Andromeda spiral nebula and other spiral nebulae lie within or outside the Milky Way.
In the 1920s Edwin Hubble finally put the matter to rest, when he identified Cepheid variable stars within the Andromeda galaxy to specify that it is indeed an "island universe" residing beyond the bounds of our Milky Way galaxy.
The Astrophotography:
Almost 10 years after. It took that long to play again in Photoshop with all those raw data of M31, the magnificent and glorious galaxy in Andromeda.
It was the better monitor which I use nowadays and the "old-wined" experience in post-processing that helped to go up to this final composite. My color-guides were all those incredibly beautiful images from many great astrophotographers, who are mostly using dedicated astronomical ccd cameras. So I am quite satisfied from what my old and trusty Canon 350Da (Baader modified) gave me.

Pentax K-3 II was mounted on Vixen Polarie. I used Tamron 17-50mm f/2.8 XR Di II LD set at 50mm.
The night was relatively hot, so I was obliged to take many exposures and I tried various settings for the exposure, aperture and ISO.
The best 58 out of 65 RAWs (DNG) were aligned and stacked in DeepSkyStacker. Further processing took place in Pixnsight LE (artificial flat frame subtraction) and CS3 (levels, curves, selective color, brightness and contrast, saturation, correcting the imperfections of the stars at the corners due to coma).

Globular Cluster Messier 80 (M80 or NGC 6093) is a globular cluster that can be found in the constellation Scorpius. This cluster was photographed in July 2015 and the final image is a stack of 18 thirty-second exposures (nine minutes total) at ISO 3200 using a Canon 6D at prime focus of a Celestron 6″ telescope. The imaging system was mounted on an iOptron ZEQ25 equatorial mount for guiding.
M80 lies at a distance of about 32,600 light-years. It is one of the densest globular clusters in our galaxy. Software used to create this image include DeepSkyStacker (for stacking the individual frames), ImagesPlus (for initial stretching and post processing), and Corel Paintshop Pro X5 and Adobe Lightroom for the final image adjustments.
From last Friday night/Saturday morning, when I only managed 6 increasingly clouded frames before it became totally overcast.
A planetary nebula is so-called because they looked like a planet to early telescope-users. In fact they form when a star blows away its outer layers in a nova.

One of my favorite targets - the integrated flux nebula (IFN) or galactic cirrus is faint dust illuminated by our galaxy, and there happens to be a nice concentration of it in the direction of Bode's Nebulae (Bode's (M 81) and Cigar (M 82) Galaxies). The Angel Nebula, which is made of IFN, is in the lower left corner. This is an improvement over my last attempt at this target - shooting raw and more integration time made a difference.

Nov 2020 update: The color of M 81 on my original version had always irked me a bit. I reprocessed it and now M 81's color is much better (in my opinion).
Using my 170 exposures of my Star Time lapse, I've stacked the images using DeepSkyStacker. Helping the brightness of the stars to come through.
I'm currently shooting at 30sec exposure and ISO100, can I increase my ISO levels by using Dark noise reduction to see more of the night sky, ie The Milky Way?

The Jellyfish Nebula (left-center) is a supernova remnant. The Monkey Head Nebula is the bright emission nebula near the bottom; the monkey head is upside down looking right here. Both are quite close - the Jellyfish Nebula is an estimated 5,000 light years from earth; the Monkey Head is an estimated 6,400 light years from earth. The large star cluster near the top is Messier 35 (NGC 2168). NGC 2158 is the other smaller star cluster to the lower right of Messier 35.

PicA guided image of the spiral galaxy M106 spiral galaxy in the constellation Canes Venatici and six of its galactic neighbors. From left to right and above M106 are NGC 4220, NGC 4231, NGC 4232, NGC NGC 4248, NGC 4217, and NGC 4226. The image was taken with a Canon 400mm f/5.6 L lens on a Canon 7D MKII dslr camera and a 30mm Svbony guide scope with a ZWOASI224MC guide camera. The final image was created from 18 115 second images combined together with Deepskystacker and enhanced with Gimp and Adobe Lightroom. M106 is 25 million light years away from Earthture saved with settings applied.
Added some more subs to this last night (4th clear night on the trot - I MUST get some sleep!) so it's now 1 hour 24 minutes. Better colour I think and I took a little more care over the processing. Also redid the core at 4 seconds.

"The night starts here, the night starts here, forget your name, forget your fear
The night starts here, the night starts here, forget your name, forget your fear
The pleasure part, the afterthought, the missing stone in the graveyard
The time we have, the task at hand, the love it takes to become a man
The dust at dawn is rained upon, attaches itself to everyone
No one is spared, no one is clean
It travels places you've never been or seen before
The night starts here, forget your name, forget your fear
You drop a coin into the sea, and shout out "Please come back to me"
You name your child after your fear, and tell them "I have brought you here"
The scary part, the aftershock, the moment it takes to fall apart
The time we have, the task at hand, the love it takes to destroy a man
The ecstasy, the being free, the big black cloud over you and me
And after that, the upwards fall, and were we angels after all?
I don't know, I don't know...
The night starts here, the night starts here, forget your name, forget your fear
The night starts here, the night starts here, forget your name, forget your fear
You drop a coin into the sea, and shout out "Please come back to me"
You name your child after your fear, and tell them "I have brought you here"
The night starts here..."

This is a reprocess of data from earlier in the year - this time I used the 'remove light pollution' and 'HSL selective color' tools of Astro Pixel Processor after integrating light frames in DSS and before editing in GIMP. Also, my flats were introducing artifacts so I didn't use them, but instead corrected vignetting with the 'remove light pollution' tool.
I'm much happier with this version - the color and definition of the nebula are much better, and seem to be accurate in comparison with other images.

M57 aka NGC 6720 is a Planetary Nebula (nothing to do with planets - long story) and is the outer shell of a red giant star that's coming to the end of its life and expelling its outer gasses (or something like that)
Another M bites the dust, and what a piddling little thing this is! Barely bigger than a fat star, I used 3 x drizzle in DSS so that I could actually see the thing. Not best imaged with an ED80 and budget kit, that's for sure. Never done a PN before :)
