Amazing how much detail there is in the RAW data, but its extremely tricky to tease it out.

This is around an hours worth of exposure, taken on the amazing Samyang 135mm f2, and a Nikon D500, and tracked on a MoveShootMove tracker.

I photographed this handsome nebula about 2 weeks ago during a nearly full moon with the Optolong L-eXtreme filter.

NGC 7380 is a "must-shoot" object in Cepheus in my books. It's a fantastic target to try with a one-shot-color camera or DSLR, but a light pollution filter with narrow bandpasses will help keep those stars from taking over.

My son and I imaged Comet C/2023 A3 (Tsuchinshan-ATLAS) last night, just after astronomic dark around 7:30 pm. I could tell it wasn't as bright as it had been a week earlier, but it will still observable with the naked eye from Bortle 4 skies.

It was a nice night for astrophotography - clear skies, temps around 40 deg F, calm, and the moon was still below the horizon. It was my first time doing 'real' astrophotography with my son (or anyone else for that matter). I enjoyed explaining what I was doing the whole time - not sure if he did :) (he was there by his choice so I don't feel too bad).

I also showed him Polaris, some constellations, and star clusters, and we took a quick shot of the constellation Lyra, so I could show him the Ring Nebula (M57). It's pretty unimpressive at 135mm focal length, but you could tell it was different than a star - it looked like a tiny, bright donut.

I've done too many different colour schemes and palettes for this data now, so i'm going back to basics for this one - h-alpha=red oiii=blue, and oiii=green. bi-colour with a red-ish tone.

might upload a different one some other time.

Only about 1.5 hrs in 5 and 10 minute exposures.

Although not really considered part of the 'spring galaxies' retinue this is an excellent time of year to image or observe this wonderful, contrasting, pair of galaxies as they are at zenith for us mid-northern latitude observers.

This is really a rescued image as the ccd camera misted over several frames into the run. It forced me to try new software to stack with as DeepSkyStacker did a very poor job (with admittedly poor data).

So this is my first attempt with Astro Pixel Processor and although I am a huge way from understanding it, it did produce a workable image for me despite endlessly telling me the image would not be properly calibrated.

I photographed this one last week using the Sky-Watcher Esprit 150 (1050mm focal length) on the EQ8.

A few more lessons learned on this one, the big one being optimizing exposure times depending on target/filter.

I shot 7-minute LUM exposures - which were not ideal. Next time around I'll shoot shorter subs and try to rack up a lot more.

First discovered by Edmond Halley in 1714. It was 50 years later when Charles Messier added the cluster to his list of objects that he was not interested in, giving it the designation M13.

The cluster is 25,000 light years away from us and can be found in the Constellation Hercules. Giving it it's more prestigious title of 'The Great Cluster in Hercules'.

M13 is one of the brightest globular clusters visible to us, especially from the Northern hemisphere. Containing over 100,000 stars it is quite easy to detect with a modest pair of binoculars and a dark sky.

Leave a comment below if you find it with some binoculars.

I collected exactly an hour's worth of data (20 x 3-minutes) through each LRGB filter (not nearly enough!) and stacked each set together in DeepSkyStacker using dark calibration frames).

The color channels were aligned and processed entirely in Adobe Photoshop to complete the image. Thanks for looking, and clear skies!

There is a lot of unglamorous work associated with owning a private observatory. In our case, we had to upgrade the telescope control system about a year ago and thereafter ensued a lot of additional upgrades and testing which revealed other problems we had not been aware of. Consequently we have cleaned the 26" primary mirror, adjusted the polar alignment, fine-tuned the tracking rate, laser-collimated the optical system, installed new dome control, installed a new auto-guiding system, added three new cameras and a new filter wheel. Each step is followed by testing an exhausting number of star images on every clear night available, which commences after our observatory guests have left around midnight.

You might guess that the glamorous part is getting to capture images of the wonders in our universe, but actually it is meeting the wonderful people who visit us and shake our hands when they leave.

Prior to this image, we had photographed the Pinwheel in April of 2021 and by a complete coincidence chose it as our live-stack object for guests about 10 1/2 hours after Supernova SN 2023ixf was discovered on May 19, 2023. At the time of discovery, the estimated magnitude was 14.9 and the object brightened significantly in our subsequent imaging to an estimated magnitude of 11 on May 22.

This image was taken on July 9, showing that the object has dimmed and while not a perfect image, we are noting significant improvement and claiming a bit of success following the work we have done on our imaging train thus far.

The Rho Ophiuchi and the Antares region are incredible glimpses of the night sky. They are full of multicolor reflection and dark nebulae.

Blue, orange, cyan and red nebulae decorate one of the most beautiful constellation of the boreal sky: the Scorpius (one of my favourites).

In this photo on the left you can see the cyan/blue Rho Ophiuchi nebula near a scythe-like dark nebula on the right. Two of the three stars inside the Rho Ophiuchi nebula are actually double stars.

Antares is on the right, just a little bit over the frame (south). That's why everything looks golden in that area (Antares is a red giant).

Unfortunately the sky was not perfectly clear that day so the photo is not like I imagined it.

I've been waiting over 2 months for a clear, Moonless night for deep sky imaging. Even by UK standards, it's been a frustrating Summer! Once the appropriate conditions finally came, they didn't last long and I only managed 3 frames.

This is part of the famous Veil Nebula supernova remnant. The bright star with the reflection halo is 52 Cygni.

Despite the limited frames, I think the result is slightly better than last year's of the same subject, as I've stopped the telescope's mirror shifting - by fitting stronger collimation support springs.

Manually, off-axis guided for 3 x 5-minute exposures at ISO 1600, f/4. Modified EOS 600D & Revelation 12" Newtonian reflector telescope.

Registered and stacked using DeepSkyStacker; initial curves adjusted in Canon Photo Professional; final curves & colour-balance adjusted using Paint Shop Pro; noise reduction via CyberLink PhotoDirector.

The second tail is faintly visible.

17 photos stacked in DeepSkyStacker. Taken with a Canon R camera and Canon EF 100-400mm f4.5-5.6L IS II lens.

Each photo 400mm, 1.3 sec. at f/6.3, ISO 16000

Rework on previous data with DeepSkyStacker 64. I think it provides better rendering. And it is much, much faster...

IC410 is an emission nebula in the constellation of Auriga. Often called the Tadpole Nebula in reference to the two tadpole shaped clumps in the upper left of the nebula.

NGC1893 is the open cluster of stars in the middle of IC410. It's these stars that are ionizing and shaping the surrounding nebula. The tadpoles themselves could be collapsing in to new stars.

The nebula is around 12 to 12,500 light years away and 100 light years across.

The open star cluster is believed to have been formed 2 to 4 million years ago.

Backyard Astrophotography from New York City - Flame Nebula (NGC 2024) and Horsehead Nebula (Barnard 33)

Canon 60Da with Canon EF 200mm f/2.8 L II USM Telephoto Lens and iOptron SkyTracker tripod.

Exposure 10sec x 148 - about 25 min total. ISO-800, f/3.2

I stacked images using DeepSkyStacker, and for post-processing used Photoshop.Photo was done Jan 31, but just today did final post-proseccing.

We had one good night of clear skies during our camping trip to Mew Lake in Algonquin Park. The seeing was acceptable but not great due to a light haze, despite the nice dark sky. This was taken looking out over Lake of Two Rivers on Thursday, July 20th to the accompaniment of howling wolves and relatively few mosquitoes. I'm actually not pleased with this image. The constellation Scorpius lies low and just above the horizon viewed from this latitude, meaning we see this marvelous cloud complex at a low slant angle though the Earth's thick and turbulent atmosphere, which filters the blue wavelengths resulting in a rather monotone image. Still, the stars are in reasonably sharp focus and the dark nebula structure looks good. This is a stack of 16 light frames (I recorded about 40 but most were ruined by meteors and aircraft!) taken at ISO 1600 for 30 seconds at f/2.0, 16 dark frames made in-camera (long exposure noise reduction), 11 flat frames and 10 bias frames, using my trusty Sigma 50mm ART lens and Canon 70D mounted on my iOptron SkyTracker. The images were stacked using DeepSkyStacker, with the final product processed in Lightroom.
