At the end of August, I captured this beautiful, faint emission nebula in Cygnus, which is rarely photographed and located between North America and Elephant‘s Trunk Nebula. SH2-124 and its surroundings offer a fascinating variety of structures and dark clouds that I processed in SHO first. Here's an alternative HOO version with a more „realistic“ look. I hope you like the picture in this bicolor version, too!

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.

This image was a cooperation with Mabula Haverkamp (the maker of astropixelprocessor) who was imaging M106 at the same time as I did. We shared our data to look what we could get out.
This is the result with a resolution of 1.36"/pixel and a limit of a magnitude of around 22.5.
We were quite happy with this result!

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.

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.

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 :)
(Formula, if you really want it:
// R:
OIII^2 + Ha/2
// G:
(Ha+OIII^1.05)/2
// B:
Ha + 0.5*OIII^2
)
This is one of those astronomy targets where I cannot quite make out the relationship between the name and the visual appearance of the object, but nevertheless this is SH2-132 or commonly known as The Lion Nebula.
I think the dark lines near the two dark areas may represent the lions mouth like an upside down Y, but who knows. This region is rich in HII, but also very rich in OIII as you can see by the blue in the image. I have produced both the HOO (Hydrogen Alpha+Oxygen III + Oxygen III as RGB) and the Hubble Palette SHO (Sulphur Dioxide II + Hydrogen Alpha + Oxygen III as RGB)

IC 1848, as known as Soul Nebula, is an emission nebula locatel in the constellation of Cassiopeia; far 7500 years light from the solar system. It conforms a great stars formation region, with visible huge extensions of ionized and excited gas. Soul nebula is integrated by many open star clusters, an intense radio source called W5 and by huge bubbles formed by the intense winds coming from massive young stars. W5 integrates large cavities that were carved out by radiation and winds from the region’s most massive stars, pushing gas together and causing it to ignite into successive generations of new stars. Dense large pillars of material can be seen around the nebula structure, pillars of around 10 light years with stars forming into them.
This image is taken through Ha, SII and OIII filters, and mapped in post-process as a variation of the SHO palette. Because of this, we can see differenciated areas, depending on the signal received. Hydrogen Alpha, Sulfur double ionized or Oxygen triple ionized. The narrowband astrophotography allows us to detect different chemical compositions of the ionized gas emited by the nebulas.
