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.

I was very lucky to be able to capture all the full moons of 2021. The image represents 12 full moons of 2021 with their popular names, distance from Earth and angular diameter. The centre piece is a mosaic made with strips from all the 12 full moons.All the images were captured with the same camera (Nikon D5600) and lens (Sigma 150-600c) at a same focal length (600mm). The individual moons are a stack of 300 images each.

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.

Acquisition, focusing, and control of Paramount MX mount with N.I.N.A., TheSkyX and PHD2. Focus with Optec DirectSync motors and controller. Equipment control with PrimaLuce Labs Eagle 4 Pro computer. All pre-processing and processing in PixInsight. Acquired from my SkyShed in Guelph. Average transparency and seeing. Acquired November 23 – December 19, 2021, mostly under a moderately moonlit sky.

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.
