NGC 2174 (also known as Monkey Head Nebula) is an H II emission nebula located in the constellation Orion and is associated with the open star cluster NGC 2175. It is thought to be located about 6,400 light-years away from Earth. The nebula may have formed through hierarchical collapse. (Wiki)

SH2-124 is a molecular hydrogen cloud in the north-east Cygnus region, in the same areas as the Cocoon Nebula (flic.kr/p/2pRZo33). It is pretty large emission nebula, but not too bright. The whole area is filled with hydrogen, hence the red hues everywhere.
I captured this on a brief 3 hour session (astronomical darkness is only about 1 hour now in my area), using my William Optics FLT132 with 1.0x flattener (910mm focal length at f6.9). ZWO ASI2600MC Pro camera with Optolong L-Ultimate narrowband 3nm Ha & Oiii filter.

While I realize this is my third version of M42 The Orion Nebula. Each was taken with a different camera/telescope. combination. These are showing my evolution in capturing deep space. This version is with a CCD Camera intended for deep space, with a Telescope. Zero cropping, this is the full photo. Guided, Ten-1 minute photos stacked and calibrated. Edit with PixInsight, Captured with Sequence Generator Pro. I'm amazed at the detail accomplished with one minute photos. As I tweak my process each time I go out, I learn new things. Please don't mind the repetition.

The Great Barred Spiral Galaxy ( NGC 1365 ) in the Constellation Fornax
Below the equator, not seen from much of the Northern hemisphere, NGC 1365 passes very nearly directly overhead an observer situated near Cape Town, as Sir John Herschel was in November of 1837, or near Sydney, as I was, almost exactly 180 years later, when I photographed this “remarkable nebula” that is numbered 2552 in his book of observations from the Cape.
Not called a “nebula” now, of course, this striking object is one of the nearest and most studied examples of a barred spiral ( SB ) galaxy that also has an active galactic nuclei resulting in its designation as a Seyfert galaxy.
At around 60 M light years from Earth, NGC 1365 is still seen to occupy a relatively large area ( 12 by 6 arc minutes ) due to its great size; at some 200,000 light years or so across, NGC 1365 is nearly twice as wide as the Milky Way and considerably wider than both the Sculptor and Andromeda galaxies.
This High Dynamic Range ( HDR ) image is built up from multiple exposures ranging from 4 to 120 seconds with the aim of capturing the faint detail in the spiral arms of the galaxy whilst also retaining colour in the brightest star ( the orange-red 7th magnitude giant, HD 22425 ). Also, scattered throughout the image, and somewhat more difficult to see, are numerous and far more distant galaxies with apparent magnitudes of 16 to 18 or greater.

I tried something different with this because of the really bright stars and the horrible micro lensing of the 1600MM. I used 20 second exposure and tried to capture as many as I could until M45 set to low for me to continue imaging. I ended up with 560 sub frames. I was hoping I could avoid 1600MM issues and still get a decent amount of nebulosity in the image.
This took me 14 iterations of processing to arrive at an image I was somewhat happy with. Trying to balance the bright stars with the dust was a challenge.
Overall I am happy with the image with only 3hrs integration. I really want to fully capture the full extent and detail of the dust and the deep saturation of the reflection elements. I could get more deeper saturation with more integration time and with different sub lengths for a HDR processed image, maybe next year!

Once everything was setup I kept warm in my own Subaru while the telescope setup ran the sequence. It is nights like these that make it all worth it. 🌌✨🔭📷

From SpaceTelescope.org, “NGC 7006 resides in the outskirts of the Milky Way. It is about 135,000 light-years away, five times the distance between the Sun and the center of the galaxy, and it is part of the galactic halo. This roughly spherical region of the Milky Way is made up of dark matter, gas and sparsely distributed stellar clusters.”

Blue Horsehead Nebula - IC 4592
This is a rarely imaged nebula, located about 400 light years from us, visible in the constellation Scorpio. IC 4592 is a true reflection nebula, being formed of cosmic dust, the central part appearing blue due to the energy released by Jabbah, the star whose light makes this nebula visible. The popular name of this nebula, Blue Horsehead, is given by the more or less obvious resemblance to a horse's head and, as most astronomy enthusiasts know, this is not the only "horsehead" visible in the night sky. Practically every night of the year a "horsehead" nebula can be seen, regardless of whether it is "blue" or "dark". As an additional note, the above statement is valid for the latitude where I am (44 degrees North).

The Rosette nebula is one of my favorite targets. The shape and detail make it one of the most interesting deep sky objects in the northern hemisphere. Located in the constellation Monoceros, it also contain the open cluster NGC 2244. This cluster provides the solar radiation that is exciting the surrounding gas and causing the striking glow.

This was a challenge to process with a mono camera. It's so much easier with a DSLR, haha.

The Orion Nebula is one of the largest and brightest deep-sky objects that exists in our quadrant of the Milky Way galaxy. It is a star forming region that consists of gas and dust that is being excited and illuminated by hot, young stars near to the center of the nebula. Given any clear and relatively dark night during the winter (in the northern hemisphere) it can been seen with the naked eye as a fuzzy "star" in the constellation Orion (look for it as the middle "star" in the sword that hangs below the belt of Orion the Hunter).
Photographed on the mornings of October 11 and 13, 2015 from my light-polluted front driveway using a 5 inch aperture, f/5.2 telescope and a ZWO ASI174MM camera (unmodified, no cooling or temperature regulation).
This is an RGB-filtered image with no narrow-band enhancements that was taken over two nights using three different exposure levels that were combined to produce a high-dynamic-range result. This is an improved version of an image that I first posted on October 13, 2015. Here is the exposure summary:
Filters: Baader RGB set
Red Exposure: 15s x 64, 4s x 96, 1s x 32 (total: 22m 56s)
Green Exposure: 15s x 80, 4s x 96, 1s x 32 (total: 26m 56s)
Blue Exposure: 15s x 64, 4s x 80, 1s x 32 (total: 21m 52s)
DF: 32 for each exposure level
Bias: a few hundred on each night
Total RGB Exposure Time: 71m 44s
Capture software Sequence Generator Pro and PhD v2. Image registration, integration, and adjustments done with PixInsight v1.08 with final tweaks in Photoshop CC 2015.

According to various googled sources, the highest dynamic range of the Nikon D610 sensor is at ISO 800. This image is a stack of three images (2 min's exposure, 300 mm, f/5.6), pre/post-processed using Pixinsight 1.8.
Westerhout 5 (Sharpless 2-199, LBN 667, Soul Nebula) is an emission nebula located in Cassiopeia. Several small open clusters are embedded in the nebula: CR 34, 632, and 634 (in the head) and IC 1848 (in the body). The object is more commonly called by the cluster designation IC 1848.
Small emission nebula IC 1871 is present just left of the top of the head, and small emission nebulae 670 and 669 are just below the lower back area.
The galaxies Maffei 1 and Maffei 2 are both nearby the nebula, although light extinction from the Milky Way makes them very hard to see. Once thought to be part of the Local Group, they are now known to belong to their own group- the IC 342/Maffei Group.
This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".
