Always a difficult object to me, so small, so dim... and always come back and I try to take something... if you've ever struggled with it, you know what I mean :D a perfect example of planetary nebula.
The Owl Nebula is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. The nebula is approximately 8,000 years old.
In that case is a little bit more that 50 hours of integration, using only a small area of the sensor because the small size of this object, heavily cropped after a drizzle process and still at 0.34 arcsec/pixel.

This is the Flaming Star Nebula (IC405) and the Tadpole Nebula (IC410). The Flaming Star Nebula is the coma-shaped nebula on the top, the Tadpole Nebula is the large, circular nebula near the bottom right. From Wikipedia, IC405 is an emission and reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. IC410 is a faint and dusty emission nebula of more than 100 light-years across approximately 12,000 light-years away from Earth in the northern constellation of Auriga. NGC 1893, an open cluster, is embedded inside IC410.

Only this Ic63 nebula, without the Gamma Cassiopiae star that always appears on captures.
It’s not on the frame but still it's possible feel the strong presence of this big star (at the up-right side of the picture) as a blue light going to the nebula.
Complex nebula to capture (only mag. 10), also with this dominant variable star close who makes so difficult obtain all details and nuances.
Gamma Cassiopeiae is a star at the center of the distinctive "W" asterism in the northern circumpolar constellation of Cassiopeia. Although it is a fairly bright star with an apparent visual magnitude that varies from 1.6 to 3.0.
Gamma Cassiopeiae is a Be star, a variable star, and a binary star system. Based upon parallax measurements made by the Hipparcos satellite, it is located at a distance of roughly 550 light-years from Earth. (star description credits: Wikipedia)

From Wikipedia: The Pelican Nebula (also known as IC 5070 and IC 5067) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbor, the North America Nebula, by a molecular cloud filled with dark dust.

There's just no shortage of cool stuff that can be found lingering around the star Alnitak in Orion's belt: the Flame Nebula (NGC 2024), the Horsehead Nebula (IC 434), the emission and reflection nebula NCG 2023, and the smaller reflection nebulae IC 431 and IC 432. Combine all of that with a generally spectacular background and you've got something.

This is the latest data that I have processed, captured from GrandMesaObservatory.com in Western Colorado and I’m using the Sky-Watcher Esprit 150mm ED F7.0 Triplet APO Refractor that Sky-Watcher USA have sent to us for testing. I acquired the data in Color using LRGB Filters and H-Alpha was added to the red channel.
This time around the camera we are using is the QHY168 Monochrome CMOS camera with an APS-C format sensor that was sent to us for beta testing. The QHY168M matched with the Sky-Watcher 150 Esprit has an image scale of 0.94 arcsec/pixel and a Field of view of 51.6 x 77.7 arcmin.
The QHY168 uses the SONY Exmor IMX071 sensor which has 4.8um pixels and 2.3e- to 3.2e- read noise.
This setup is “System 2” and one of 3 telescopes currently available through Grand Mesa Observatory’s Subscription services which you can read more about here: grandmesaobservatory.com/equipment-rentals/

The Triangulum Galaxy is the third largest galaxy within the Local group, behind Andromeda and our own Milky Way. Found in its namesake constellation of Triangulum, this galaxy bears the distinction of the most distant object which can be seen with the naked eye and is a wonderful example of a classic spiral galaxy. It has enjoyed a rather quiescent life, having evolved without any major tidal interactions with other galaxies and its structure is very uniform as a result.
In 2007 astronomers using the Chandra X-ray Observatory, in orbit around Earth, detected the largest stellar-mass black hole ever found within M33. The 16 solar-mass black hole has an obital stellar companion, and from our vantage point, the black hole eclipses its binary companion, blocking its view, every 3.5 days.
M33 is also an important object to astronomers because it is the ultimate gauge for the darkness of a location. It takes just a tiny bit of light pollution to eliminate this object from view.

This huge nebula in the northern constellation of Auriga is IC410 but it is best known for the two "tadpoles" near its centre.
This image is an integration of data shot with H, O and S filters and some RGB too on an ASI294MM camera behind a William Optics Zenithstar 103 telescope. All post-processing was carried out in PixInsight.
A combined image of data of my own (Tom M.) and from the Digitized Sky Survey II. The detail in the DSS-II images is incredible, data I obtained using a modest 71mm scope shows the yellow clouds of the Milky Way as a fuzzy cloudy mass with some stars resolved, combining my image with DSS-II the clouds are resolved into an innumerable field of stars. If you want to see just how many check out the full version of this image here:

In this image the major areas of nebulosity of the constellation Sagittarius can be seen, the Lagoon Nebula (M8) the bright reddish one in the center, the Trifid Nebula (M20) the red and blue one towards the upper left, and last but not least NGC 6559 which is the red/blue somewhat dimmer area of nebulosity below the Lagoon Nebula.
Another prominent feature('s) is the dust-lanes and yellow clouds of the central bulge of the Milky Way towards the right. There are also a couple Globular Clusters, NGC 6544 just below and to the right of the Lagoon Nebula, and NGC 6553 which is further to the bottom right appearing in this image as a fuzzy bright spot in the clouds of the Milky Way. Finally there is the open cluster M21 down and a little to the left of the Trifid Nebula.

The M81 and M82 galaxies are a pair of galaxies located in the constellation Ursa Major.
M81 (also called the Bode's Galaxy) is a spiral galaxy that lies approximately 11.8 million light years away from us, its size is approximately 45000 light years.
Its neighbor, M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth, this Galaxy measures about 18500 light years.
It took me 5 nights to take this picture. 3 nights with the LPRO Filter & 2 with the L Extreme filter (to get the Hydrogen Alpha / Red)
As it was the last possible target for me before the Galaxy Season, I decided to increase the exposure time and tried to get some Integrated Flux Nebula (IFN) but it was too faint and the light Pollution won the battle.
I'll try to get longer exposures next year (10min or maybe 15 min) as a last try to get this damn IFN.
Clear Skies to you all !

IC 443 (also known as the Jellyfish Nebula and Sharpless 248) is a galactic supernova remnant in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth (ref: Wikipedia).

This is 6.2 hours of data taken at Hawker, South Australia about 2 weeks apart, 4.7 hours of Astronomik 12nm Ha filter taken during a near full moon and the remainder taken between cloud breaks on a near new moon with no filter. I have previously posted UHC filter data used as colour with Ha as luminance, I think this is a little better. I haven't yet tried to incorporate the UHC filter data with the RGB as previously that wasn't a great result, but may try later. I took about 4 hours of Optolong L-Pro filter from metro Adelaide to add to this but I'm not impressed with what I got, and it was ruined by sensor dust that moved before I got flats dammit! Anyway, the main nebula name here is NGC6188, The Fighting Dragons in Ara, which isn't well known in the northern hemisphere. This just isn't as colourful or bright as some other targets, I'm not totally happy with this but realistically may not improve on it much. Calibration, registration, gradient removal, combining RGB and Ha as luminance and some work on star colour, saturation in Astro Pixel Processor, which is really good for this deep sky stuff, but not without issues. Final tweaking in Photoshop (which is much easier to edit photos in). Nikon D810A, Astronomik Ha filter, 600mm focal length f/4, Celestron CGEM II EQ mount, ZWO guide camera, APT camera control. RGB shots 10 minutes at ISO200, Ha shots were 10 minutes at ISO800.
I've been working on this shot for a few weeks now, the heart nebula is a tough one to image with a DSLR, signal is faint and any light pollution makes it very tough without narrowband filters. I recently got an Optolong L-enhance filter which has made doing narrowband a lot easier with my modified D5300. This is 50 x 10minute exposures shot with a full-spectrum D5300 and Astrotech AT65EDQ on a Sirius EQ-G mount.

What flowers in this field of dark star dust? The Iris Nebula. The striking blue color of the Iris Nebula is created by light from the bright star SAO 19158 reflecting off of a dense patch of normally dark dust. Not only is the star itself mostly blue, but blue light from the star is preferentially reflected by the dust -- the same affect that makes Earth's sky blue. The brown tint of the pervasive dust comes partly from photoluminescence -- dust converting ultraviolet radiation to red light. Cataloged as NGC 7023, the Iris Nebula is studied frequently because of the unusual prevalence there of Polycyclic Aromatic Hydrocarbons (PAHs), complex molecules that are also released on Earth during the incomplete combustion of wood fires. The bright blue portion of the Iris Nebula spans about six light years. The Iris Nebula, pictured above, lies about 1300 light years distant and can be found with a small telescope toward the constellation of Cepheus. [Text adapted from APOD]

An image with some unusual colour contrasts for a deep-sky image — with blue Bellatrix, a green comet, and the huge red Lambda Orionis nebula.
This is Comet ATLAS (C/2020 M3) seen here as the green glow above the bright blue star Bellatrix in the shoulder of Orion, and approaching the large diffuse red nebula surrounding the “head” star of Orion, Lambda Orionis. aka Meissa. The large nebula complex is catalogued as Sharpless 2-264. At right, above the comet, is the smaller emission and reflection nebula catalogued as vdB (vandenBurgh) 38. The sparse star cluster surrounding Lambda Orionis is Collinder 69.
This was the night of November 15/16, 2020, with the comet moving rapidly northward a day after its closest approach to Earth and three weeks after its perihelion, or closest approch to the Sun. On the next nights the comet would have been within the nebula.
This is a stack of 8 x 8 minute exposures without a filter, blended with 6 x 15-minute exposures through an Optolong L-Enhance narrowband nebula filter, to bring out the faint nebulosity.
The comet image itself is from just one of the filtered frames layered and masked to reveal just the comet. But even in the single 15-minute exposure its image trailed slightly as its motion was quite rapid. I used a filtered shot for the comet as its green/cyan glow did pop out more than in the unfiltered shots, though the more usual cyan colour of a comet has been altered a little by the narrowband filter and its bandpass of the green OIII lines.
All were with the William Optics RedCat 51mm astrograph at f/4.9 and with the Canon EOS Ra, with the filtered shots at ISO 3200 and unfiltered shots at ISO 800. Images were autoguided, with dithering, using the Lacerta MGEN3 stand-alone autoguider. I also used its polar alignment routing this night to refine the mount’s polar alignment and it seemed to work!
All images stacked, aligned and blended with Photoshop.
Shot a batch of hydrogen alpha subs on the crescent nebula. Bright moon and misty conditions deterred me from trying anything else besides the Ha.. Hopefully get a chance to shoot other filters for this nebula to create some colour for the image, especially OIII to try and capture that faint blue 'envelope' that appears in OIII.
Looks okay in black n white h-alpha though so I thought i'd post it by itself.

Dedicated to the Love of my Life in her 41st Birthday!!!!
I worked on this one over several nights collecting data for the final photo from Aberaeron and Salisbury.
The Jellyfish Nebula (IC 443, Sharpless 248) is a supernova remnant located in the constellation Gemini. It lies approximately 5000 light years from Earth and can be found between the stars Mu and Eta Geminorum, at the foot of one of the celestial Twins.
The Jellyfish Nebula is a remnant of a supernova that occurred in the Milky Way between 3000 and 30000 years ago. The supernova event produced the nebula and a neutron star. The presence of the neutron star and the nebula’s location in a star forming region indicate that the remnant was created by a Type II supernova, one triggered by a rapid collapse and violent explosion of a star with a mass at least 8 times that of the Sun. The neutron star is moving away from the site at about 800000 km/h.

What is that bright star high in the Western sky after sunset? Say hello to Arcturus (a red giant star), also known as Alpha Boötis (the brightest star in the constellation Boötis). It is the brightest star in the northern celestial hemisphere. It has a visual magnitude of −0.04, and is the fourth brightest star in the night sky. The name Artcurus comes from the Greek meaning "keeper or guardian of the bear", which refers to the its position adjacent to the tail of the constellation Ursa Major (the Great Bear).

The rather obscure emission nebula catalogued as Sharpless 2-261, at top, but commonly known as Lower’s Nebula after the father and son team of amateur astronomers, Harold and Charles Lower, who in 1939 built an 8-inch Schmidt camera astrograph, one of the first, and used red sensitive plates and red filters to record these kinds of red nebulas. They noted this object on their plates, in northern Orion. They were certainly pioneers of this type of filtered astrophotography.
At bottom is the small star cluster NGC 2169, also known as the X-Y Cluster or Number 37 Cluster as its two clumps of stars, just resolved here, resemble those letters or numbers with a little imagination at the eyepiece.
At bottom left is the small emission nebula Sh2-269. The larger fainter patch above it is Sh2-267. The small nebula at the left edge might be Sh2-266 but charts are unclear and contradictory.
This is a stack of 5 x 8-minute exposures unfiltered at ISO 800 with a stack of 6 x 10-minute exposures at ISO 1600 shot through an Optolong L-Enhance filter to bring out the nebulas, all with the old Hutech filter-modified Canon 5D MkII DSLR and the SharpStar HNT150 Hyperbolic Newtonian astrograph at f/2.8. What the Lowers would have given to have such technology in their day!
Taken with some haze in the sky toward the end of the shoot for the unfiltered shots, adding the star glows. Taken from home February 22, 2020.
This is a two-panel mosaic of nebulas and clusters in southern Gemini and northern Orion.
The Messier 35 star cluster is at top accompanied by the smaller cluster NGC 2158. At left near the orange star Eta Geminorum is the crescent-shaped Jellyfish Nebula, IC 443, a supernova remnant. The fainter, diffuse nebula at far left is IC 444. At bottom and over the border in Orion is the Monkeyhead Nebula, NGC 2174. The little round nebula above NGC 2174 is Sharpless 2-247.
This is a mosaic of two segments for the northern and southern halves of the scene, with each half being a stack of 6 x 8-minute exposures at ISO 800 with no filter, plus a stack layered in of 6 x 8-minute exposures at ISO 3200 with an Optolong L-Enhance filter to bring out the faint red nebulosity. So this is a stack and blend of a total of 24 exposures. Alll were with the Canon EOS Ra camera on the SharpStar HNT150 Hyperbolic Newtonian astrograph at f/2.8.
34,000 light years away towards the constellation of Canes Venatici lies the impressive globular star cluster Messier 3 (NGC5272). It contains upwards of half a million stars and is actually heading our way. M3 is moving towards our solar system at approximately 147.6 Kilometers per second!
