Abell 61 is a planetary nebula situated in the constellation Cygnus. As a remnant of a dying star's outer layers, it showcases a spherical shell of ionized gas, illuminated by the central white dwarf star. The intricate structures within the nebula are a testament to the star's final stages of evolution. Abell 61's presence in the night sky allows astronomers to delve into the complex processes that occur during a star's demise, providing insights into the universe's continuous cycle of creation and transformation.

We are glad to propose you this beautiful picture of Abell 35 . It was taken with a Planewave CDK12.5 and a QHY600 M camera in Chile during several nights of january and february 2021. The resulting image is a mix of RGB band images for the stars and HO images for the nebula itself.As you are probably aware, Abell 35 still remains considered as PN on SIMBAD but Jacoby had already raised questions about its true nature as early as 1981. Recent studies (after Frew and Parker, PASA, 27, 129, 2010) conclude that the nebula is a Stromgren sphere in the ambient ISM, ionized by a hot DAO white dwarf companion of BD – 22º 3467 which has recently evolved from the PN phase. The system produces a strong wind, probably from the fast, rotating subgiant which interacts with the inner zone of the emission nebula to produce a dramatic parabolic bow-shock aournd BD – 22º 3467 that is strongly visible in the OIII narrowband datas.

A classic of the spring sky: the duo of the galaxy M108 with the Owl planetary nebula (M97) in Ursa Major.M97 is 2000 LY away, while M108 is 32 millions LY away (16.000 times more distant).I completed the LRGB with exposures with Ha and especially OIII, in order to gain signal on M97: the much more faint outer ring of M97, not so often seen, is visible.Takahashi TSA102 - AZEQ6 - Atik Cameras AtikOne 6.0 - Filters Astronomik (6nm Ha / OIII)L : 36 x 600s bin1RGB : 3 x 24 x 300s bin 2Ha : 12 x 600s bin 1OIII : 18 x 600s bin 1 + 12 x 600s bin2Total : 19h3, 4 & 5 april 2021 - Fouras (France)Traitement : Pixinsight & Photoshop

Another bright planetary nebula to capture during a full moon.
NGC 1501 is a complex planetary nebula in the constellation Camelopardalis.
It's progenitor star is a pulsating star, meaning that its brightness varies regularly and periodically. In the case of NGC 1501’s progenitor star, this is incredibly fast, with the star’s brightness changing significantly in just half an hour.

Recovery of the helix nebula, with more than 60h of retained poses (out of 90h), captured over three months. I think I've reached the limit magnitude of my sky, impossible to make the signal come out more from the bottom of the sky. The Helix Nebula is a planetary nebula located in the Aquarius constellation, near the Southern Fish. Its strong resemblance to a human eye has earned it the nickname "the eye of God".

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.

The large and older planetary nebula, PK 080-10.1, was just discovered in the 90s of the last century by Motch, Werner and Pakull (hence the name MWP, which was formed from the initials of the discoverers' names. When they examined a weak X-ray source in the swan. The X-ray source turned out to be the central star of a planetary nebula. The central star is not a normal white dwarf, but a pulsating star of the type GW Vir. GW Vir stars pulsate with periods of less than one hour through non-radial gravity waves.

HFG 1 is a very old large, low-surface-brightness planetary nebula in Cassiopeia. It surrounds, and was produced by, a binary star system (V664 Cas) that is moving rapidly through our Galaxy. V664 Cas is comprosed of a white dwarf star and a large red giant. The two stars are very close and rotate around their common centre of gravity every 14 hours. The star system is moving towards the lower left of the image. As HFG 1 plows through the interstellar medium, a bluish bowshock is produced; and a red trail of gas is left behind in its wake.
