An H II region emission nebula in the constellation Cassiopeia, about 11,000 light years away. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575.

Image Description and Details : HFG-1 was discoverd in 1982 by Heckathorn, Fesen and Gull. Its central star is actually a binary star system, V664 Cas (magnitude 14) that is moving through our galaxy. V664 Cas consists of a white dwarf star and a large red giant, rotating around their centre of gravity every 14 hours. As HFG 1 moves through the ISM a bowshock is produced in front of it as well as a red trail of gas in its wake. Outer diameter about 15 arcmin.

Image Description and Details : LDN 1622, also referred to as the Boogeyman Nebula, is a dark nebula that appears against the glowing Hydrogen of Barnard’s Loop in the constellation of Orion. However, LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only 500 light-years away. Its foreboding appearance lends this dark nebula its popular name, the Boogeyman Nebula.

The small oval structure just left of centre of Sh2-232 is a planetary nebula, PN G173.5+03.2. Another faint planetary appears as a small yellowish haze around a star just above Sh2-235.

Image Description and Details : There is a grouping of reflection nebulae in Orion - NGC 1977, NGC 1975, and NGC 1973 - usually overlooked in favor of the substantial glow from the nearby stellar nursery better known as the Orion Nebula. Found along Orion's sword just north of the bright Orion Nebula complex, these reflection nebulae are also associated with Orion's giant molecular cloud about 1,500 light-years away, but are dominated by the characteristic blue color of interstellar dust reflecting light from hot young stars.

The Fox Fur Nebula is a nebula (a formation of gas and dust) located in the constellation of Monoceros not far off the right arm of Orion and included in the NGC 2264 Region.

The image is a close-up of a small section of a much larger complex, generally known as the Christmas Tree cluster. The Cone Nebula is also a part of this same cloud.

The red regions of this nebula are caused by hydrogen gas that has been stimulated to emit its own light by the copious ultraviolet radiation coming from the hot, blue stars of the cluster. The blue areas shine by a different process: they are mainly dust clouds that reflect the bluish light of the same stars.

Its popular name arises because the nebula looks like the head of a stole made from the fur of a red fox.

Image Description and Details : ​Located on the edge of a vast cloud of natural gas, about 10,700 light-years away in the constellation Perseus, NGC 1491 (also called the Fossil Footprint) is an H II region (a large, low-density cloud of partially ionized gas in which star formation has recently taken place). Its central star (BD +50 886), is a young blue star with an 11.22 magnitude whose stellar winds are blowing a bubble in the surrounding gas.

Image Description and Details : AR3190 is one of the largest sunspots of the new solar cycle 25, when we observe it with a telescope it is really impressive to see this dark spot on the surface of our star.
What is this dark hole? Did the surface of the sun go out in that area? None of this, it's just an illusion! Sunspots are "cooler" than the surrounding surface due to the action of strong magnetic fields and this creates the illusion of a dark spot, but in reality it is still very hot, about 4000K in the umbra (the dark core of sunspot). The darkness of a sunspot is only a contrast effect.

To take this picture I used a Sky Watcher Maksutov 180 telescope, a Baader astrosolar film, a Powermate 2X, a Player One Photosphere filter, and a Player One Apollo-M camera.

Image Description and Details : IC 1795 (Fish head), is a diffuse nebula identifiable in the constellation of Cassiopeia, towards the border with the Giraffe. It is part of an extensive nebular complex that is the site of very active star formation which includes the areas W4 (Heart Nebula) and W3 (IC 1795 and NGC 896).
For the acquisition of the signal, very narrow band filters (3nm) were used in order to create the Hubble palette which associates HII, OIII and SII to the G, B and R channels.
A total of 21 hours of exposure were required, carried out in the Valle degli Ulivi (Taranto-Italy) at 80m a.s.l.

Image Description and Details : Just above the witch in the sky hovers a praying mantis…..

It fascinates the mind that our ancestors chose to name many objects in the sky based on animals and some of the names which come to mind are the Scorpion, the Bear and even a Dragon. Continuing in the same vein and keeping to traditions, in my mind’s eye I see NGC 1788 as a Praying Mantis. That it lies in close proximity to IC 2118, the Witch Head nebula gives it an even more sinister character. The star Beta Eridani / Cursa shines brightly creating a strong halo while the ionised hydrogen gases in the region contrast it in bright red emissions. The blues from the reflection nebulae and the dust in the region all combine together to form a rich smörgåsbord of color….

IC 1396 is a stunning emission nebula located in the constellation Cepheus. The bright central star, HD 206267, ionizes the surrounding gas, causing it to glow in brilliant hues of red and blue. The nebula's distinctive shape, often referred to as the "Elephant Trunk," is created by dense columns of gas and dust that shield the nebula's interior from the ionizing radiation. The trunk of the elephant is also a site of ongoing star formation, with several young stars visible within the structure. IC 1396 is a beautiful example of the ongoing processes of stellar birth and death in our galaxy.

Image Description and Details : M45 (Pleiades) in HOORGB, 98 hours taken over the course of 19 nights.I've wanted to take this picture for a couple of years, but whenever I could get to my dark sky site, it was cloudy. The stars finally aligned (literally) and I was able to get a good amount of RGB data from my dark sky site this winter.During my research for taking this photo, I noticed that some images had small amount of faint Hydrogen Alpha immediately around M45, so I figured I'd pile on some HA data for my wide field image and see if any more hydrogen would present itself...I was pleasantly surprised to find some wispy streams of hydrogen that I'd never seen before, right outside of the star cluster.The RGB data was taken from my dark sky site in Bone Cave, TN. The narrowband data was taken from my backyard in Nashville, TN.Imaging details:Imaging Telescope: TPO UltraWide 180 f/4.5 Imaging Camera: ZWO ASI2600MC Pro Mount: Sky-Watcher EQ6-R Pro Filters:Baader Fringe Killer 2"Optolong L-eXtreme 2" Accessories: ZWO ASIAIR Plus, ZWO EAFSoftware: Adobe Photoshop, Aries Productions Astro Pixel Processor (APP), Pleiades Astrophoto PixInsightGuiding Telescope: ZWO 30mm Mini Guider ScopeGuiding Camera: ZWO ASI290MM Mini Dates:Nov. 18, 2022, Nov. 19, 2022, Nov. 20, 2022, Nov. 21, 2022, Nov. 22, 2022, Nov. 23, 2022, Nov. 28, 2022, Nov. 30, 2022, Dec. 12, 2022, Dec. 15, 2022, Dec. 16, 2022, Dec. 17, 2022, Dec. 18, 2022, Dec. 19, 2022, Dec. 20, 2022, Dec. 23, 2022, Dec. 24, 2022, Dec. 25, 2022, Dec. 27, 2022, Jan. 1, 2023Frames:Baader Fringe Killer 2": 538×240″ (35h 52′) (gain: 100.00) -10°COptolong L-eXtreme 2": 467×480″ (62h 16′) (gain: 100.00) -10°CTotal Integration: 98h 8′Darks: 60Flats: 60Flat darks: 100
