DeepSkyStacker would not work with the Ha Subs but Affinity had no trouble. Successful outcome but HEQ5 Pro struggling with 13.3Kg payload (limit 11Kg for imaging), EQ6R Pro already on wishlist.
IC 1396A - The Elephant's Trunk Nebula, or even more unofficially the lady walking away, Mufasa on pride rock, I mean it looks like anything you see.
This is a dark cloud of dust and gas in a much larger cloud of ionized gas illuminated by a very bright massive star (HD 206267).
Shot the "blue" data last night using my Esprit 100ED S-APO, the lack of Moon meant I could get some detail and contrast, though the OIII component to this nebula is very faint.
Was a great night to just sit on the beach whilst my scope imaged and watch Orion rise over the cliffs and see a small number of "shooting stars".
My first take at the famous Leo Triplet, a group of three interacting spiral galaxies: M 65, M 66 and NGC 3628. The latter is seen edge-on from Planet Earth, so that a prominent dust band patty is seemingly wedged inside a bun of light - hence also its popular moniker "The Hamburger Galaxy". The group of galaxies is about 32 million light years away. Prominent in the top left corner is the bright start Theta Leonis, or Chertan, which can be rather easily seen also from (sub)urban locations. Near the top of the image are also two smaller, fainter galaxies, NGC 3596 (~ 50M light years, to the left) and NGC 3593 (~24M light years, right above the Triplet).
I acquired this image with my trusty TAIR-3S (300 mm, @f5.6) and Samsung NX30 combo on the Star Adventurer tracking mount. A total of 456 subs (30s, ISO 3200) were recorded over two nights, once from the Isartalsternwarte Königsdorf, and once at Ringberg Castle sitting above the Tegernsee.

The most prominent galaxy in this image is known as Messier 61 (the 61st object in the catalog created by Charles Messier). Its shape and structure make it a barred spiral galaxy, while its history and formation make it a starburst galaxy. This galaxy is about 52 million light-years away and there about 300 billion (with a B) stars in the galaxy.
While I am mesmerized and awed at the scale of those last two numbers, it is also worth noting that M61 is just one of at least 5 galaxies in the picture I captured.
I've been running my telescope/camera for hours upon hours lately and working tirelessly at processing the resulting images, so although each one usually takes multiple days and nights, I hope to be churning out more soon :).
This particular image came from 3 hours of RGB data. 20x180s in Red, Green, and Blue... stacked in DeepSkyStacker, combined in PixInsight, and tweaked in Lightroom.

I stacked 8 30-second exposures (and 3 dark frames) using DeepSkyStacker. This helped reduce noise and allowed me to aggressively process the resulting image. This is my first attempt at doing this, so I'd appreciate any helpful feedback.
The foreground was processed in a second pass through DeepSkyStacker, without de-rotation, and the result masked into the sky image.

M42 - THE GREAT ORION NEBULA AND RUNNING MAN - Jan 2021
Ok, this is my final version of this subject for this year. I added another 2 and a half hours of data, to make this a total final exposure of 5 hours.
This is an HDR image created by blending 3 different exposure lengths after stacking and initial processing in Photoshop. It is the first time I've really tried to complete a full HDR image and I think the core of M42 has turned out OK. You can still see detail in the bright Trapezium core region, as well as still seeing fainter details in the outer nebulosity.
I am super happy with the look of this final image, it's muted and has a slightly dreamy colour balance, some will say I've pushed the data too far, but I like it.
Thanks for looking and sharing, comments always welcomed.
Clear skies.

This, I am reliably informed by my software, is the cluster M34 aka NGC 1039, chillin' up there somewhere in Perseus. With some spikes of course, to make it a little less uninteresting. Charles Messier must have had bloody good eyesight!

This is enough data so i could use only basic processing in PI: DBE, HistogramTransformation, a little SCNR to remove green and a little curves adjustment. So no BackgroundNeutralisation, no ColorCorrection, no Noise reduction etc.

M57 (NGC 6720) is probably one of the most recognizable Messier objects. It is a planetary nebula found in the constellation Lyra, referred to as the Ring Nebula, and lies about 2,300 light-years from Earth. M57 is the glowing remains of a sun-like star. The star expelled a vast envelope of ionized gas before becoming a white dwarf.

This is the open cluster designated NGC 7419 in the constellation Cepheus. This cluster is between 7,500 and 11,000 light years away. Its location is behind some dark nebulae which reddens the color of the stars. The cluster does contain no less than five red supergiant stars - this is one of my favorite open clusters!

Haven't been around these parts much lately, but managed a couple of images in the meantime.
This is another collaboration between myself and Dave Williams, who provided the Ha used as luminance. My first mosaic, it consists of three frames (well, two and a tiny little strip in between really) processed using photomerge in Photoshop, which I was impressed with. Several sessions between July and September 2013
Meaningless stats follow:
RGB:
SW ED80/EQ5
Canon 500D modded, Baader Neodymium filter
All three frames: 246 subs totalling 13 hours 28 minutes
Acquisition: APT
Guiding: Quickcam Pro4000/9x50 finderscope, PHD
Stacked in DSS and processed in CS5, using photomerge for the stitching together

Stacked with DeepSkyStacker.
A spiral galaxy in the constellation Camelopardalis.
It goes by the nickname of the Hidden galaxy as it's a very difficult target for visual and for photography. This is due to it lying pretty much in the same line of sight as the Milky Way and all it's bright stars and dust lanes. Except IC342 which is about 11 million light years further on.
Boring techie bit:
Skywatcher Quattro 8" Newtonian Reflector steel tube with the f4 aplanatic coma corrector, Skywatcher EQ6 R pro mount, Altair Starwave 50mm guide scope, ZWO asi120mm guide camera mini, ZWO asi533mc pro cooled to -10c gain 100, Optolong L'enhance 2" filter, ZWO asiair plus.
Darks, Flats & Bias.
Stacked with DeepSkyStacker and processed in StarTools & Affinity Photo.
Also known as Caldwell 49 and NGC 2237.
The Rosette is an emission nebula in the constellation Monoceros some 5,000 light years away.
It's thought to be responsible for the birth of some 2,500 stars. A group of which can be seen near the centre, this is the open star cluster NGC 2244 estimated to be about 4,000,000 years old.
Boring Techie bit:

Camera: ZWO 533mc pro
Filter: Optolong L'eNhance.
Guided and controlled by the ZWO asiair+
Best 90% of 40 light frames 180 seconds each.
Stacked with darks, flats, dark flats & bias with DSS.
Processed using Graxpert, PixInsight & Affinity Photo.
Thought I'd take the opportunity to capture the comet, currently in Andromeda, again. The sky was less murky than last night, but it's likely to be the last clear night for a while.
22 x 30-sec exposures at f/4 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens on a Vixen Polarie star tracker. The frames were stacked on the comet in DeepSkyStacker, with curves adjustment and further noise reduction in post-processing. Also Starnet++ software used to temporarily separate the stars and comet and prevent the stars bloating when comet contrast is stretched; this has revealed more of the tail that would otherwise be lost in the star background.

Known has the Silver Needle galaxy.
This edge-on loose spiral galaxy is about 13.5 million light years from us in the constellation Canes Venatici. It's estimated to be 65,000 light years from end to end.
Captured on the 6th of March 2024.

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years from Earth in the constellation Ursa Major. The giant spiral disk of stars, dust and gas is 170,000 light-years across — nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulas. These nebulas are areas of intense star formation within giant molecular hydrogen clouds. Brilliant, young clusters of hot, blue, newborn stars trace out the spiral arms. (ref: Wikipedia and NASA)
