M44 IC4665 Summer Beehive Cluster
This is a first light from a revamped setup where the camera and mount have been upgraded. The conditions were not ideal, the wind was moderate with gusts up to 16mph and the ambient temperature was in the teens deg C.
Processing didn't go as smoothly as I had originally hoped, with Pixinsight failing to register red and green filter lights. AstroPixelProcessor struggled with the light pollution mainly contained within the luminescence frames, however I was pleased with the the inital performance of the ZWO ASI533MM Pro.

Building further on the 48 (50) panel mosaic i added a row of 16 panels to include the Veil nebula Complex.The registration RMS error is only 0.1 pixel.......
As a basis for this Mosaic I used 70 separate stacks (also made with APP) with integration times between 45 and 345 minutes each depending on the object in the frame. An all new mosaic registration algorithm was used that is capable of truly sub pixel perfect registration of these large Mosaics. And the whole process is fully Automatic. The full size version is 29320x35386 pixels giving 1038 Megapixels).
That is not practicle for web use, but this upload is a 50% reduction and still a 120 Megabyte JPG.

The Integrated Flux Nebulae (or Galactic Cirrus) are high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way. These IFN are very faint and were discovered in 2005 by Steve Mandel. This mosaic shows sections of 2 main Nebula in the Mandel-Wilson Catalogue, the Volcano Nebula (MW3 near Messier 81/82) and the Angel Nebula MW2.

Photographing Space Image of the week: 4 Nov. 2019: photographingspace.com/iotw-nov-04-2019/
Knight Observatory, Tomar
It'd been awhile since I'd been astrophotographing - felt great to be out under the stars and a smokeless sky. Fall is a excellent time for widefield astrophotography in the western US - there's a decent amount of astronomic dark, plenty of clear nights, temperatures aren't too cold, and quite a few interesting widefield subjects are available.
My goal with this small mosaic (only 2 panels) was to capture both the Fireworks Galaxy (NGC 6946, tiny here, bottom left) and the Elephant Trunk Nebula (IC 1396) in the same extent, with all of the interesting nebulosity in between, most notably the dark nebula Barnard 150 (AKA the Seahorse Nebula) in the lower left, one of my favs.
Surprisingly, I didn't detect much of the red emission Flying Bat Nebula (Sh2-129, center), part of which actually appears bluish (?, at first I was excited that I might have detected the Giant Squid Nebula (OU4), but nope, the blue is not in the right place). Previously I had captured Sh2-129, albeit faintly, with this same set up in the same location.
Part of the reason for this is that I stopped my Samyang 135mm down a half stop to f 2.4 (which I usually shoot wide open at f 2), not to tighten up stars, but to flatten out the heavy vignetting a tad. It did make a difference, but I did also notice that the Elephant Trunk Nebula didn't show up as strongly as expected based on my previous imaging of it. I'm still undecided whether I'll stay with f2 or move to f2.4, might depend on the subject.
There is a decent amount of what appears to be blue reflection nebulosity around star HD 198793 in the upper left quadrant; looking at widefield images of others, I can also see this faintly, but I haven't been able to find any closer images of it yet and it isn't cataloged in my astronomy app (SkySafari 6 Plus). It's possibly a processing artifact although it doesn't appear to be one.

Holy Bat Signal, Batman !
On 31 October 2025, The European Southern Observatory (ESO) released an image of a nebula captured with the VLT Survey telescope with data mostly in visible light (but incorporating some additional infrared data from ESO's Visible and Infrared Survey Telescope).
Located between Circinus and Norma the image showed a huge cloud of gas and dust, shaped like a cosmic bat. This is a stellar nursery where new stars are forming and releasing enough radiation to energize the surrounding hydrogen gas, causing it to shine red. The darker, thread-like features resemble the bat’s skeletal wings. These filaments are cooler and denser than the surrounding material, with dust particles that obscure the starlight behind them.
I can find only one amateur image of this "cosmic bat" on the internet.
The VST is a 2.6 metre instrument with a 268 megapixel camera and is located at Paranal in Chile. ( As an aside remember the Bond villain's hideout in Quantum Of Solace? that's the accommodation for the Paranal Observatory :)).
In contrast I have a 100 mm telescope and a 9 megapixel camera; fortuitously this turned out to be just right to capture the bat in entirety, though it took me half an hour or more to get the framing right.
RCW 94 is the right wing of the bat, followed by RCW 95, which forms the body, while the other parts of the bat are very very faint and have no official designation.

I shot this area with this exact framing last December, but wanted to improve my image. This time my focus was better (I didn't have a Bahtinov mask then), I shot and processed raw (jpeg last time), and I used Astro Pixel Processor tools for processing.
The only thing that wasn't better this time around was my tracking - I only used 50% of my subs, many of which still had slightly trailed stars; I think my balance was off. I would have liked more integration time, but still got a result I'm happy with using only 35 minutes of data.

✨ Voyage au cœur de la constellation d'Orion ✨
Après 4 heures de prise de vue et près de 30 heures de travail, avec 4 versions différentes à la clé, voici le résultat de ma dernière session d'astrophotographie.
J’ai capturé une partie de la majestueuse constellation d’Orion avec mon 135mm, mettant en lumière les subtiles nébuleuses qui peuplent cette région de notre ciel hivernal.
Durant ces 4 heures d’acquisition, j'ai aussi réalisé une série d’images sous-exposées pour mieux révéler le cœur de la nébuleuse d’Orion. Un grand merci à mon ami Harry Collis pour ses précieux conseils, sans qui je n'aurais peut-être pas atteint ce résultat avec autant de facilité. 🙏
Orion, la star de l'hiver, n'arrêtera jamais de nous fasciner et de nous inspirer, nous les astrophotographes du monde entier. ✨

LDN 673 (upper right quadrant) is one of those dark nebula that I often stopped to admire when surfing astroimages. I was excited to find that I could capture some of its structure at 135mm, and that it would fit nicely in the same 135mm extent with the more frequently imaged Barnard's E. This shot has been planned for awhile but took me awhile to get to.

Sharpless Sh2-10 is an emission nebula located in the constellation of Scorpius. It’s very rarely imaged despite being, so to speak, in plain sight between two of the most popular targets in Scorpio-The Lobster (aka The War and Peace ) Nebula and The Cat’s Paw Nebula. It is quite faint but presents interesting structure even when imaged with a small telescope.
This image was constructed with four hours of Ha data acquired with a Sharpstar Z4. 2 hours of colour data was acquired with a William Optics RedCat51. Ha and RGB data was stacked in AstroPixelProcessor. and the stacked images were registered and aligned in APP.
The registered and aligned images were cropped and processed in PixInsight
after gradient extraction with the SetiAstro ADBE script, the RGB image was plate solved and Spectrophotometrically Colour Calibrated.
Blur X was NOT applied on RGB- it was found to create " worms" -artefacts after stretching.
Stars were removed with StarNet ++ and the starless image was stretched with GHS.
A similar process was followed for the Ha data except Blur X was run twice, SPCC was not used (obviously)
After GHS stretching Dark Structure Enhance and Local Histogram Equalisation processes were run
starless RGB and Ha were combined using the combine Ha with RGB script
The resultant image was blurred with light deconvolution and a LRGB image was constructed using the combine LRGB script
Stars were processed using the SetiAstro star stretch script and added to the starless image with Pixelmath

Although small, NGC 2266 is a nice cluster, it has stars of diverse colors that not as well presented with short exposure necessary due to the comet's motion requiring only a few minutes of capture. The different colors of the stars within the cluster is quite apparent even with short integration time. Aligned on stars, the comet although slow moving against the background is a little elongated from motion. AstropixelProcessor and Photoshop processed.
Comet C/2017 K2 (PanSTARRS) continues to brighten but is still quite faint, though positioned fairly high in the sky overnight. It will likely get somewhat brighter as it approaches closest to Earth in July. Last night the comet appeared near the loose open cluster IC 4665 in the constellation Ophiucus as our streak of clear nights continues.

Here's a little experiment. The dotted line is the International Space Station (ISS) passing through the field of view of my small telescope, very near the interesting little object known as NGC 246, a planetary nebula sometimes called the Skull Nebula in the constellation Cetus.
This wasn't by chance. Watching for these sorts of coincidences, I consulted the trusty sky simulation software SkySafari and noticed that the path of the station would take it in front of a few interesting features in the sky, in addition to this one: M13, the Great Hercules Globular cluster in Hercules, Vega, the brightest star in Lyra, and The Veil Nebula in Cygnus.
Because of the tremendous difference in brightness, I captured the ISS and the nebula field separately. (The ISS is the third brightest object in the night sky, after the Moon and Venus). For the ISS pass, I made a short video with a Nikon Z 6 mirrorless camera and Explore Scientific 102mm f/7 refractor. The image of NGC 246 was made afterward with a ZWO ASI294MC camera and Nikon 80-200mm f/2.8 lens @200mm, 15 6-minute exposures processed in Astro Pixel Processor and Lightroom. The ISS track is in the correct position and scale, composited in Photoshop. In addition, the inset is an enlargement of a few video frames and shows some detail in the ISS.
