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.
This image consists of the same data as the RGB Image but has been processed using my tutorial on creating SHO images from One Shot Colour Cameras which you can read here:

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!!!

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.

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.

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.

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)

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.

There's another bright-ish comet in the sky: 19P/Borelly, now the second brightest after the departing Leonard (which is best visible from the southern hemisphere now). I captured this from suburban Bloomington, Indiana. The green coma is very prominent (from emission of carbon molecules) and there's a narrow, straight tail just visible above the sky background. Also in this frame is a galaxy, NGC 275, the fuzzier streak at upper left, some 79 million light-years away.

I am very happy to present the second image in which these interstellar shells can be seen at all, and at the same time, it is the first photo to show the shells so clearly thanks to the long exposure time.
Thanks to several clear nights in the fall, I was able to collect nearly 39.5 hours of narrowband data with the RASA at f/2, along with an additional hour of RGB for the stars. The processing was certainly challenging, but I managed to bring out many details in the OIII structures and the surrounding H-alpha clouds.
A few details about the objects in the image:
The bluish filaments in the center are listed in Simbad as “interstellar shells” with the designation GSH 122+02-77. These are not direct supernova remnants but rather part of the interstellar medium (ISM)—low-density material (mostly gas) that exists between stars. Stellar winds and nearby supernovae can interact with this material, forming irregular shells. The neighboring Wolf-Rayet star HD 4004 (WR1) could possibly be responsible, although there are no definitive research results on this yet.
In the upper left, you can see Sh2-181 with a pronounced OIII shell, while Sh2-175, a small emission nebula, is located on the right.

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.
