This was taken with my 11″ SCT, Hyperstar, ASI 294 MC Pro, and Optolong L-Pro filter to reduce light pollution.
The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy distanced 21 million light-years (six megaparsecs) away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain on March 27, 1781 and was communicated to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
This was shot with my 11″ SCT, Hyperstar, ASI294MC Pro, and an Optolong L-Enhance narrowband filter. 40 60 second images were stacked to make this.
The Omega Nebula, also known as the Swan Nebula, Checkmark Nebula, and the Horseshoe Nebula (catalogued as Messier 17 or M17 or NGC 6618) is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier catalogued it in 1764. It is located in the rich starfields of the Sagittarius area of the Milky Way.
I shot this with my 11″ SCT and Hyperstar, 40 60 second subs stacked. This could use a longer focal length than the 532 mm provided by the Hyperstar but it did a good job anyway. I used an Optolong L-Pro filter to reduce light pollution.
Messier 13 or M13, also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of several hundred thousand stars in the constellation of Hercules.
M13 was discovered by Edmond Halley (of comet fame) in 1714, and cataloged by Charles Messier on June 1, 1764 into his list of objects not to mistake for comets; Messier’s list, including Messier 13, eventually became known as the Messier Catalog.
