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 :

Jones-Emberson 1, a.k.a the Headphone Nebula, is a northern planetary nebula. It is also catalogued as PK 164+31.1. It is located about 1600 light years away in Lynx. The red and green glows are mainly due to emissions from hydrogen and oxygen atoms, respectively. The nebula’s brightness is listed as magnitude 14.1, but it is relatively large, so the light is spread out and it has a very low surface brightness.

This image includes galaxies that lie millions of light years away, thousands of times further away than the nebula. Look for streaks and smudges that look obviously different from the sharper, rounder stars.

Image Description and Details :

Visible to the naked eye, the Seven Sisters, or the Pleiades, is one of the best known open clusters. The blue reflection nebula around it is a popular target for imagers. Very deep images, like this one, show the surrounding faint clouds and tendrils of dust as well as some red H(II) emission regions.Acquisition, focusing, and control of Paramount MX mount (unguided) with TheSkyX.

Image Description and Details :

M22 might be the most famous northern globular cluster, if only it rose higher for people at mid-northern latitudes. It is beautifully set in the Milky Way in Sagittarius. It’s in the same league as M13 in terms of splashiness, even though it is dimmed by being so much lower in my sky. It’s among the nearest globulars, at around 10,600 light years from Earth, and it covers an area about the size of the full Moon in our sky. It is around 100 light years across and is pegged at around 12 billion years old.SBIG STL-11000M camera, Baader R, G and B filters, 10″ f/6.8 ASA astrograph, Paramount MX.
