Image Description and Details :

NGC 2442 is located around 50 million light-years away in the constellation of Volans. The galaxy is 75,000 light-years wide and has quite an peculiar shape featuring two dusty spiral arms extending from a central bar that gives it a hook-like appearance. Given its appearance it is often referred to as “The Meat Hook Galaxy.” The galaxy’s distorted shape is most likely the result of a close encounter with a smaller galaxy some time in the past. A considerable amount of IFN is present in the field proximate to the galaxy and the image shows faint star streams at the ends of the arms of the galaxy.Imaged in LRGB and H alpha OTA CDK 1000 Luminance, RGB and H alpha.

Image Description and Details :

This image shows a marvelous and busy area in the constellation Cassiopeia. It contains a large amount of dust, several dark nebula and several reflection nebula along with two interesting stars. Near the top center is the star SU Cassiopeiae which is a Cepheid variable at Mag 5.94. SU Cass is a Yellow giant with a spectral class of F5:lb-11. It's 19 times larger than our sun. SU Cass lies 1289 light years distant. Surrounding it is the blue reflection nebula VdB 9 which is lit up by SU Cass. The blue wisps extend quite a ways around this area. The other interesting star in the lower center left is the star RZ Cassiopeiae. RZ Cass is a white A3V main sequence star at mag 6.26. It's an eclipsing variable star which is 219 light years distant. The bluish nebulosity surrounding it is listed as VdB 7. However RZ Cass is apparently not the source to light up VdB 7 but another smaller 11th mag star nearby. Several dark nebula are right of center in the image. The upper part of this nebula looks like an opened hand, hence the nickname (The helping hand). The dark area of the hand, near the top finger is designated as LDN 1357 and below it near the palm, LDN 1355. The long dark area near center right is the dark nebula LDN 1358. Throughout this entire area encompassing the field of view is lots of molecular dust of varying thickness and color. This image was taken under the dark skies of the Okie Tex Star Party in October 2021. It encompasses 14.3 hrs of exposure time using LRGB filters.Scope: Stellarvue SVX 152T, Camera: ZWO ASI 6200mm Pro, Mount: Paramount MyTExposures: Luminance 59@300sec, Red 39@300sec, Green 38@300sec, Blue 36@300secProcessing: PixInsight

Image Description and Details :

Abell 13 is highly evolved planetary nebula in Orion. It is sometimes known as the Orion Ring Nebula because it's morphology resembles the better known Ring Nebula, M57. However Abell 13 is much fainter at around mag 16. In both cases their oval shape is believed to be a result of them being bipolar nebulae viewed offset from their axis, making their ring structure appear oval. Abell 13 is 2.9 arc minutes in angular size and around 3,500 light years away. It was first catalogued as Abell 9 by George Abell in 1955, but renumbered as Abell 13 in his 1966 paper.

Image Description and Details : Sh2-132 is one of the 312 bright emission nebulae catalogued by Stewart Sharpless. This large area of emission nebula in the constellation Cepheus glows from the characteristic red light of ionized hydrogen. Sh2-132 is about 1,200 light years away. Dark patches within it are due to soot blocking out the light. There are also some prominent dark nebulae blocking out the light of the stars behind them outside the main area of Sh2-132.

Image Description and Details : 2 Panel Mosaic of the Witch Head nebula

As the name implies, this reflection nebula associated with the star Rigel looks suspiciously like a fairy tale crone. Formally known as IC 2118 in the constellation Orion, the Witch Head Nebula glows primarily by light reflected from the star. The color of this very blue nebula is caused not only by blue color of its star, but also because the dust grains reflect blue light more efficiently than red. A similar physical process causes Earth's daytime sky to appear blue as well.

Image Description and Details : Sharpless 126 (Sh2-126) is the designation of a large emission nebula in Lacerta, which appears in this image as a red background and exceeds the edges of the image. The source of its ionization is the intense ultraviolet radiation from the star 10 Lacertae, a blue main sequence star.

The nebula, which forms a "stellar funnel" in the center of the image and snakes away to the right, is designated LBN 437. It is a molecular cloud whose densest part is associated with some bright young stars. Its most striking feature is a symmetrical reflection nebula associated with the Herbig Ae / Be star V375 Lacertae. This star is also responsible for the bipolar Herbig-Haro objects within the nebula. Herbig-Haro objects are small nebulae around young stars. They form when gas ejected by the star hits dust clouds.

Image Description:

I have updated my large mosaic of the Milky Way with the high resolution imaging I did in 2021. The upper image is taken through H-alpha, SII and OIII filters and the lower one through HaRGB. All the major nebulosity is now taken at a focal length of 530mm. This gives the image very crisp detail when viewed as a whole. Other images around the major nebulosity were taken at focal lengths of 85mm and 14mm. This mosaic has a total of 216 panels and over 2200 hours of imaging time. It uses data taken over the last 3 years which is why in the HaRGB image Jupiter (which looks like a very bright star) is above Sagittarius and in the SHO image which I took 12 months later it is below. That's how far it moved in a year.

The historic launch of JWST took place on 25th December 2021. The visuals were sudden as we did not expect to come across the Ariane V rocket from West Bengal. Initially we thought it to be a comet (including Leonard for a moment) and confirmed the object sometime later. It was a "Dream come true" for us.

The first image shows Ariane V trailing past Sculptor Galaxy. The second image is a sequence captured over 15 minutes and the third image was its first visuals.

Image Description and Details : Is this a painting or a photograph? In this classic celestial still life composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines near the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colourful stars. Like the common household items that still life painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in this setting -- a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-years across.

Image Description and Details :

I was rather reluctant to take the object on given my bortle sky scale of 8 and how few clear nights we have had this year in Michigan, USA. I decided to give it a shot anyways, however. It really could of used twice the amount of integration time I have into it, though. It was extremely hard to process and pull out the detail. I have learned over the years that doing narrowband imaging evens the playing field with highly light polluted skies like mine EXCEPT when the object is faint like this one.

EGB 4 (Ellis-Grayson-Bond 4) is a binary star system that is not well understood. In most cataclysmic variables, matter from a normal star accumulates on the surface of the companion white dwarf star, eventually causing a nova-like flare as the material becomes hot enough to ignite nuclear fusion. In this case, however, light appears to flicker unpredictably, and an unusually large wind of particles is being expelled. The wind creates a large bow-shock as the system moves through surrounding interstellar gas. It lies about 2500 light-years away toward the constellation of Camelopardalis.
