5 x 10-minute exposures at ISO 1600.
Canon EOS 600D (modified by DSLRAstromod), Meade ED 127mm f7.5 telescope, manually, off-axis guided. Sub-exposures registered and stacked using DeepSkyStacker software.
The stars are rather bloated, especially towards the lower left, as unfortunately the camera was not fitted exactly square on the telescope. I didn't realise until I went to process the images the next day. I've done this before, ironically the last time I photographed this same object!
12x 60s subs stacked in DeepSkyStacker (10 Darks, 20 Flats, 20 Bias) processed in PixInsight and Photoshop. Canon EOS 450D DSLR prime focus Sky-Watcher 150P Newtonian EQ3-2 mount. Baader Neodymium filter.
This is the famous Whirlpool galaxy in Canes Venatici.
Imaged through an 8 inch f/8 GSO RC on an EQ8. Camera was a modified Canon EOS 700D with cooling, which kept the sensor at 0 degree Celsius. The ambient temperature was between 26 and 28 degree Celcius (about midnight). The transparency in the first night of imaging (25-26/06/2022) was pretty bad and in fact there was a moderate Saharan dust event. The backgrounds of the frames I took in the second night (22-23/07/2022) were much darker. I still combined both sets.
No filters were used.
The 57 x 3 minute exposures (total of 2h51m) were stacked with DeepSkyStacker in sigma clipping mode (dark, flats and bias correction applied). Regim didn't want to load the image, which I carefully flattened in Fitswork before, so I didn't do a B-V colour calibration, but relied on my white balance settings. Nearly all further processing was done in Affinity Photo in the following order: 1. background neutralisation and level adjustment; 2. increase in vibrance and saturation; 3. adjustment of gamma value and black point; 4. slight denoise of the entire picture; 5. sharpening of galaxies only with the clarity tool; 6. crop. In the end another slight noise reduction with Noiseware.
As usual, it could have done with more exposure time to bring better out the star tidal tails.
Having been given “the day off” from looking after our new arrival, I
have just spent the entire day doing astro related stuff… its been
awesome :)
Anyway, one of the things on my to-do list was to spend to more time
processing my Rosette data from a while back, taking on board the
various comments that have been made about it. Just finished 4 hours of
playing with this, and included the following improvements:
- better contrast in the rosette itself
- less “salmon pink”, more red
- removed the cyan halos around the stars in the left of the image
- added a tiny amount of the Ha into the blue channel (about 12% looked
about right)
Also took on board some of the items covered at the SGL Imaging day,
specifically the keeping color saturation without losing detail, and the
Shadow/Highlight tool, plus managed to get a good star reduction on the
image.
So, here we go….

This is M27, the Dumbbell Nebula. This image paints a similar future of our very own Sun. Billions of years from now, the Sun will loose its outer layers and expell them into space, just as this star did. A fellow astronomer a few hundred to a few thousand lightyears away orbiting a different star, may see a similar scene peering towards us. By then, the year will be roughly 5 billion A.D.

I was curious what the other astro imagers here used for stacking DSLR images? I have come across a few free packages beside the pricey Registax that seem to do the job well, but am noticing that the final image rendered is lacking any colour output. Might be the operators fault though. :-)

Also, I can't seem to get Registax 5 or Astrostack to work with DSLR images. Is there a size limit for the files - anyone know? If I scale them down to 1024x768 they seems to stack.

This galaxy is considered to be one of the brightest galaxies that Charles Messier missed or chose not to add to his famous catalog. It's around 50 million light years from earth.
23.5 Minutes of exposure in 47x 30 second shots, shot on a Canon T1i at prime focus on a Meade 10inch SN-10AT telescope with a light pollution filter. Exposures stacked in Deep Sky Stacker. Another 19 exposures were thrown out due to vibrations or tracking errors in the telescope mount.
This one really needs longer exposures. To show the arms of the galaxy even as faint as they are required a lot of stretching, bringing out a lot of noise in the image.
If you view the larger size on black, on a bright computer screen, and squint the right way, you will notice 7 or 8 much smaller galaxies, 3 or 4 are located near the big galaxy ... but probably 10x further away.

-23C at the time of this shot. Fantastic seeing, with poor transparency.
I managed to snag Comet Hartley 2 with the Nikkor 50mm f/1.4 AI lens. The comet is that green fuzzy just below Cassiopeia near the centre-right of the photo. It's nearing its closest approach to Earth on October 20 at 11 million miles away. There are reports it's beginning to sprout a tail.
A widefield image of the Elephant's Trunk Nebula... I wanted to capture the dark nebulosity surrounding IC1396 and show the scale of this massive nebula.

Quelques tentatives réussies de capturer la comète C/2012 S1 ISON. Malheureusement, la queue ne se détache que très mal du fond du ciel. Les raisons peuvent être le début de l'aube et la présence de la Lune presque pleine, bien qu'à l'opposé. Je tenterai de combiner les 17 fichiers d'assez bonne qualité avec Deepskystacker ou IRIS.
Some attemps of capturing Comet C/2012 S1 ISON. Unfortunately, the comet's tail doesn't detach that clearly from the background sky. Reasons can be the approaching dawn and the almost full Moon, although it was far in the sky. I will try to stack the 17 good files I made in Deepskystacker or IRIS.
I imaged the comet again, but I think nothing was gained over the last photo from 10 March. It wasn’t helped by the drifting high cloud and numerous satellite trails, traces of all of which can be seen in the final result, despite being averaged over 13 frames. 2 tails are visible, however - the ion tail towards the 1 o’clock position, and the fainter dust tail towards 2 o’clock.
13 x 30-sec exposures at f/4.5 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 was 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.

I've recalibrated and stacked and worked this image a few times since I first attempted it. Each time I come back with one more bit of knowledge.
This time, I'm still calibrating with Maxim. What's new is that I'm calibrating with 2C increments. Thus, for the 10 lights, there's two sections for calibration. This significantly reduces the over and undercorrection that I was seeing before. Also, it makes the post process a lot easier to manage.
Same details as before:
10 lights total, each at 600 seconds and 400 ISO.
Scope was the Orion 127mm Maksutov Cassegrain guided by a ST80 with SSAG.

Calibrated to make FITs in Maxim. Then debayered and stacked in DSS 3.3.3 beta 47 with kappa 2 5 iterations.
Processed in PI: dynamic crop, dbe, masked stretch, masks made from extrated lightness, these maskes used on atrous and deconvolution, multiscale media transform used on the remaining layers to boost the brightness of the nebulosity, unsharp mask, new mask from lightness, curves used on positive and inverse of this mask to bring up saturation and rgb as well as drive the background lower.

Taken at Calstar 2012 on the nights of September 13 and 14 while I was waiting for other targets to rise.
Heavily cropped due to poor framing. I would have liked to include more of the original mosiac, but the amp glow on the edge makes it difficult to smooth out these errors.
Stack of 21 subs of 10 minutes at 400 ISO using the cooled, full-spectrum Pentax K10D on the Stellarvue SV4 telescope at prime focus. Temperature range varied from 24-29C so I had to match darks with groups according to temperature. 100 total darks used to correspond to the range.
Stacking done with DSS 3.3.3 beta 47. PI 1.7 used to crop, annotate, apply DBE, masked stretch, and some NR. Final step in LR3.
I probably will return to this data set to see if I can reduce the size of the stars. There was some trailing caused by PEC and poor polar alignment.

This photo was submitted as part of the Hoohaa52 Challenge. This week's topic was "Your Choice."
I happened to step outside this night and saw a nice view of the night sky. Having recently been looking at some astrophotography and reading about some of the newer techniques (compared to when I last made a semi-serious effort), I thought I would try a simple shot. This picture is actually a composite of four separate images. It was more about testing the software and learning how it went wrong. For example, I took no flat fields or dark frames. I shot with foreground objects that would blur as I combined images due to the earth's rotation (the software does alignment based on the stars). I purposely left a light on to illuminate the trees though, so that is not a mistake.
This has me itching to try some more shots. However, I did learn that the hotspot problem on my camera has gotten worse so it is even more important that I take those extra shots to help make it easier to subtract out the hotspots. I know this is a problem that can develop over time with digital sensors, but I can't help but wonder why the problem started after getting my camera's sensor cleaned? I did take it in to someone at a camera repair shop, but it still makes me wonder.
This particular view does show the constellation of Scorpius but I am able to detect a deep sky objects as well. In particular, I can see M4, M6, M8 and M20. Here is a chart.
