Messier 92 (also known M 92, or NGC 6341) is a globular cluster of stars in the northern constellation of Hercules. It was discovered by Johann Elert Bode in 1777, then published in the Jahrbuch during 1779. It was inadvertently rediscovered by Charles Messier in 1781 and added as the 92nd entry in his catalogue. It is about 26,700 light-years away from the Solar System. It is one of the brighter of its sort in apparent magnitude in the northern hemisphere and in its absolute magnitude in the galaxy, but it is often overlooked by amateur astronomers due to angular proximity to bright cluster Messier 13, about 20% closer. It is visible to the naked eye under very good conditions.

Purgathofer-Weinberger 1, PuWe1 ( PN G 158.9 + 17.8 ) is a large, circular planetary nebula in the constellation of Lynx.
PuWe1 was discovered by Alois Purgathofer and Ronald Weinberger in 1980 on the Palomar Deep Sky Survey prints. The nebula is one of the largest planetary nebulae visible in our skies, with a diameter of 20 arc minutes. PuWe1 is also one of the nearest known planetaries with a distance of only about 1200 light years.

Planetary nebula KjPn 8 (PN G112.5-00.1, K3-89) and Bubble Nebula (NGC7635) in the constellation Cassiopeia.KjPn 8 (PN G112.5-00.1, K3-89) is a bipolar planetary nebula which was discovered by M.A.Kazaryan and Eh.S.Parsamyan in 1971 and independently by Kohoutek in 1972. It is one of the strangest and possibly most unique planetary nebulae in the sky. In my image, we see it on the left side of the frame below the center. Planetary nebula consists of a compact red core (apparent size is about 3–4 arcsec in diameter) surounded by a huge bipolar lobe structure that measures 12x5 arcminutes. There is the possibility that the two separate structures are two separate planetary nebulae formed from both members of a binary star system moving onto the planetary nebula phase within a few thousand years of each other.

Image Description and Details :

AMU 1 (PN G075.9+11.6) is a bipolar planetary nebula in Cygnus.AMU 1 is a faint but extremely strange and beautiful planetary nebula with a size of 5x2 arcminutes. It was discovered by the astronomers Alba Aller, Luis Miranda and Ana Ulla in 2013 and was found in the field covered by the Kepler telescope. It has a complex multishell morphology and a series of low ionisation structures and has a binary central star with orbital period of 2.93 days.As far as I know, this is the first amateur color photo of this nebula. In appearance, I would even give it a name - "Peaceful Atom".This image taken over several nights in September, October 2020.R-channel - 34 x 150 sec. bin 1x1;G-channel - 34 x 150 sec. bin 1x1;B-channel - 34 x 150 sec. bin 1x1;Ha- 60 x 900 sec. bin 2x2;OIII- 55 x 900 sec. bin 2x2.Total integration time about 33 hours.My setup: Telescope 8" Celestron Schmidt-Cassegrain (SCT) CPC800 GPS (XLT) on the equatorial wedge, focal reducer Starizona Night Owl 0.4х, Feq=864mm, camera Starlight Xpress Trius SX694, SX mini filter wheel, filters Astrodon LRGB E-series gen.2, Astrodon Ha 5nm, Astrodon OIII 3nm.Capture and processing software: MaxIm DL6, PHD2, PixInsight, StarTools, Photoshop CC, Zoner photo studio 14.North at the top.
