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.

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.

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.

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.

✨ 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. 🙏

The area around the well-known "Ghost of Cassiopeia" had been on my agenda for a while, and this year I was finally able to make it happen. Once again, I wanted to use my fast f/2 optics and a 400mm focal length to capture not only RGB data but also as much H-alpha signal as possible across the entire region. My goal was to show how deeply IC 63 and IC 59 are embedded within the H-alpha clouds. For this, I gathered 9.5 hours of RGB and 6.75 hours of H-alpha data.
To ensure that the beautiful reflection nebulae of IC 63 and IC 59 weren’t completely overwhelmed by the narrowband data, I combined the H-alpha data in this area with the RGB data using continuum substraction. Finally, I invested a few more hours in finding a good balance between the RGB and narrowband components for the final image.
Hope you like it!!!

The Elephant's Trunk Nebula or IC 1396 as it is otherwise known, but never with such a wide field of view, at a distance of around 2400 light years from earth and is mainly illuminated by a single bright star. It is thought that this region of space is home to a pretty young star forming region.

I added another half hour of imagery to what I already had, so this image consists of 65 minutes of data. After shooting it this latest time, I realized that I hadn't been balancing my tracker correctly when shooting south, so when I image it again this fall, I hope to be more efficient with getting non-star-trailed 60-second subs.

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
I've seen a number of images lately of the famous comet 67P/Churyumov-Gerasimenko* and thought I'd try my own. Here's the result from last night, clear enough after a modest snowfall during the day though with temps flirting with 0ºF overnight.
I'm a bit baffled by the tail that seems to be offset from the nucleus, which I don't recall seeing very often except in comets that are much closer to the Sun and sporting both ion and dust tails, and some oddball hybrid comet/asteroid objects.

What's in a colour-palette? Back when I first produced this as a regular HOO image in glowing red and purply-blue, I also experimented with a weirder palette in PixInsight, more like OHO but with a few tweaks. Figured the resultant blue-green tonality would suit this time of year much better :)
