The Orion Nebula, also known as Messier 42, M42, or NGC 1976, is a diffuse nebula situated south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun.

The moon was right next to the FOV, so the exposure had to be reduced on postprocessing. Still a nice shot!

That's what went through my head when I first stumbled across the Double Cluster h & chi Persei (a.k.a. NGC 869 & NGC 884) through my small, newly-bought amateur telescope. Of course, when I recently had the rare chance of observing this magnificent pair through 16" double-newtonian "binoculars", the view was even more stunning...
Also astrophysically, the objects are something quite rare, as they appear to be two young open clusters that are not only a chance alignment, but actually gravitationally bound siblings!
Still, it's a great and easy-to-find object (actually even visible as a faint smudge to the naked eye under reasonable skies) that's a pleasure to look at in anything from handheld binoculars to high-end amateur telescopes. And it seemed a fitting target to try out my new camera, a Canon M50 Mk. II, together with the 1000 mm f/10 Maksutov lens, which frames the two clusters just nicely. Plus, it's close enough to the celestial pole that I can actually use the 1000 mm focal length on the Star Adventurer for once.
I'm quite happy with the new cam, as it also has a much more powerful live view than my old trusty Samsung NX30, making object alignment soooo much easier if you can also see a few fainter stars on the display.

The Beehive Cluster (also known as Praesepe (Latin for "manger" or "crib"), M44, NGC 2632, or Cr 189), is an open cluster in the constellation Cancer. One of the nearest open clusters to Earth, it contains a larger population of stars than other nearby bright open clusters holding around 1,000 stars. Under dark skies, the Beehive Cluster looks like a small nebulous object to the naked eye, and has been known since ancient times. Classical astronomer Ptolemy described it as a "nebulous mass in the breast of Cancer". It was among the first objects that Galileo studied with his telescope.
Age and proper motion coincide with those of the Hyades, suggesting they may share similar origins. Both clusters also contain red giants and white dwarfs, which represent later stages of stellar evolution, along with many main sequence stars.
Distance to M44 is often cited to be between 160 and 187 parsecs (520–610 light years), but the revised Hipparcos parallaxes (2009) for Praesepe members and the latest infrared color-magnitude diagram favors an analogous distance of 182 pc. There are better age estimates of around 600 million years (compared to about 625 million years for the Hyades). The diameter of the bright inner cluster core is about 7.0 parsecs (23 light years).

The Cocoon Nebula in Cygnus is a star-forming region with a diameter of about 15 light-years and lying several thousand light-years from Earth.
The nebula itself is powered by the bright star visible near it's center and contains a cluster of young hot stars. Framed against an extremely dense star field, it seems to punctuate the end of a sinuous 2 degree long dark nebula cataloged as Barnard 168. With the Cocoon glowing at magnitude 7.2, the blackness of the dark nebulae surrounding it makes for a wonderful contrast to the Cocoon itself and results in a spectacular view in larger instruments.
Image Details: The attached images were taken Jay Edwards on June 17, 2018 simultaneously using (left) an 80mm f/6 triplet apochromatic refractor (ED80T CF) connected to a Televue 0.8X field flattener / focal reducer and (right) a vintage 1970 8-inch, f/7 Criterion newtonian reflector. The 80mm was piggybacked on the 8-inch, and the scopes utilized twin (unmodded) Canon 700D / t5i DSLRs.
These optics were tracked using a Losmandy G-11 mount running a Gemini 2 control system and guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor which itself was piggybacked on top of the 80mm apo.
The attached composite image was constructed using, relatively speaking, extremely small stacks of short 1 minute sub-exposures, and consists of only 20 minutes total exposure for the 80MM shot & 30 minutes for the 8-in image (both in addition to applicable dark, flat & bias frames), and thus contains far more noise than we would normally produce.
Processed using a combination of DeepSkyStacker, PixInsight and PaintShopPro, as presented here it has been re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
Given such short exposures I was intrigued by the results and look forward to taking deeper shots when this object is once again conveniently placed in our evening skies next summer.
A wider field image of this object taken in August of 2016 and showing the extent of the dark nebula in this region can be found at the link attached here: www.flickr.com/photos/homcavobservatory/30655875511/in/al...
Another object imaged earlier in the same session as the M42 image last night, the Elephants trunk in Cepheus. Used my 1000D with 7nm Ha filter to capture 9 subs at 12mins apiece through the 6",ISO set at 1600. Stacked in Deepskystacker,then used processing software to split the RGB channels and discarded the green and blue channels. Processed in Photoshop to reduce noise and bring out detail. Image taken midnight 23/10/16
This is something I've always wanted to do with a halfway decent camera and some software. Unfortunately, not near the city lights like I did here.
The image is a composite of 10 consecutive shots. A great freeware program called DeepSkyStacker was used to line up the stars, stack the images and filter out any anomalous sensor data from the camera.
The foreground portion with the farm field was masked-in using photoshop from a single image as the composite blurred this portion due to the earth's movement. You can still see the blur in the silhouette of the trees however. I thought this added a nice touch to the finished product though.
Next, I will try to do this away from city lights now that I understand the process a little better.

This picture whas my first stacked pictures made with my new (second hand) Meade ETX-70 telescope. I used a T-adapter and T-ring for mounting my Nikon D50. I also used an Sigma 1.4 Teleconverter to have some more zoom. This picture is the result of 37 pictures of 15seconds exposure, that i have stacked with DeepSkyStacker. I used ISO1600. I realy like the result for such cheap telescope.

This worked out well, except reviewing the images I think I can go up to 15 minutes exposure without saturation of nebula cloud.

- www.kevin-palmer.com - I shot this picture with a cheap Vivitar 200mm f3.5 lens on an iOptron Skytracker. It is a stack of 11 2-minute, iso 1600 shots. The quality of this lens isn't that great. There's a lot of coma and the brighter stars are bloated. But it still captured a surpising amount of detail in the 2 galaxies. This was taken at Sand Ridge State Forest, which has moderately dark skies.

Another quick shot of nebulosity in the Milky Way, this time the Heart & Soul Nebulae in Cassiopeia. These are both relatively faint (Magnitude 6.5) so need much more light than I've captured here. Unfortunately a looming weather front cut short my observing session and a very rough and ready polar alignment limited the exposure time on each shot.
The Heart & Soul Nebulae are emission nebulae lying approximately 7500 and 6500 lights years respectively from Earth. At the centre of the Heart Nebula (so called because of its resemblance to a heart) is an open cluster of stars referred to as Melotte 15. The small ball of nebulosity above and to the west of IC 1805 is emission nebula IC 1795.

Also had terrible amp glow so this is quite severely cropped to get rid of it. For some reason the darks didn't do their job. Anyway, not a bad result considering the short exposure.

La nebulosa de Orión, también conocida como Messier 42, M42, o NGC 1976, es una nebulosa difusa situada al sur del Cinturón de Orión. Es una de las nebulosas más brillantes que existen, y puede ser observada a simple vista sobre el cielo nocturno. Está situada a 1.270±76 años luz de la Tierra, y posee un diámetro aproximado de 24 años luz. Algunos documentos se refieren a ella como la Gran Nebulosa de Orión, y los textos más antiguos la denominan Ensis, palabra latina que significa "espada", nombre que también recibe la estrella Eta Orionis, que desde la Tierra se observa muy próxima a la nebulosa.
La nebulosa de Orión es uno de los objetos astronómicos más fotografiados, examinados, e investigados. De ella se ha obtenido información determinante acerca de la formación de estrellas y planetas a partir de nubes de polvo y gas en colisión. Los astrónomos han observado en sus entrañas discos protoplanetarios, enanas marrones, fuertes turbulencias en el movimiento de partículas de gas y efectos fotoionizantes cerca de estrellas muy masivas próximas a la nebulosa.

IC 2118 (also known as Witch Head Nebula due to its shape) is an extremely faint reflection nebula believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant star Rigel in the constellation of Orion. It lies in the Orion constellation, about 900 light-years from Earth.
