M 2-55 and its elusive fragmented bow-shock front

Image Description and Details: M 2-55 is an evolved rarely-imaged planetary nebula in the constellation Cepheus. It was first discovered and identified by the German-American astronomer Rudolph Minkowski on photographic plates at Mount Wilson in 1947. The plates were taken by W.C. Miller with a 10" f/5.2 refractor.
IM 2-55 possesses two sets of bipolar lobes.
It was only in 2020 that a team of Chinese professional astronomers detected an arc of material running from the SE to the SSW. (Chih-Hao Hsia et. al, March 13th 2020, “Discovery of Extended Structures around Two Evolved Planetary Nebulae M 2-55 and Abell 2”). They concluded that this arc was furnishing strong evidence for an interaction of the expanding nebula of \m 2-55 with its surrounding interstellar material. The presence of fragmentation in the arc may be the result of a phenomenon known as Rayleigh-Taylor (RT) instabilities.

First image of planetary nebula Si 1-2

Observations of Si 1-2 and other planetary nebulae contribute to our understanding of stellar evolution, as well as the recycling of material within galaxies. The intricate shapes and structures of these nebulae showcase the dynamic interplay between stars and the cosmos, reminding us of the ongoing cycles of creation and destruction that shape the universe.

NGC 1514

Image Description and Details : NGC 1514 is a planetary nebula in the constellation Taurus. It is also known as the Crystal Ball Nebula. It is 1520 light years from Earth. The nebula originated from a binary star system with the designation HD 281679 from the Henry Draper Catalogue. The bright, visible component is a giant star, while the nebula-generating companion is now a hot, sub-luminous O-type star. The two have one of the longest known orbits for any planetary nebula, with a period of about 9 years.
Captured on my remote observatory in Spain.

Ltnf 1

Image Description and Details : LTNF 1 is an extremely faint and rarely-imaged highly-evolved planetary nebula in the constellation Ursa Major. It is a high-excitation nebula with an eclipsing binary star system (BE Ursae Majoris) at its centre which has resulted in its unusual morphology. It is around 5,000 light years from Earth. It is so transparent that galaxies can be seen through it. It was discovered by James Liebert, Richard Tweedy, Ralf Napiwotzki and Michael Fulbright in 1995. A joint project with Sven Eklund.

Kohoutek 1-6

Image Description and Details :

Kohoutek 1-6 (K 1-6) is an evolved low-surface brightness planetary nebula in the constellation Draco. It is an asymmetric planetary nebula with a binary central star. It has an approximate size of 198 arc seconds and is around 3,000 light years from Earth. It was discovered by Czech astronomer Luboš Kohoutek in 1962. It has a bow-shock structure which is attributed to interaction with the interstellar medium (ISM).I could only find one other image of this online - captured by the Capella Observatory in 2019.

Image Description and Details : Messier 97 - a planetary nebula in Ursa Major sporting its faint OIII Halo. It is approximately 2,030 light years from Earth.
I was pleased to be able to tease out some of the structure of the faint outer OIII halo - especially as most of the OIII data was captured from my Bortle 8 sky in London because Spain has been clouded out for the past month.

K2-1

Image Description and Details :

K2-1
A very faint and obscure planetary nebula some 3700 light years away in the constellation Auriga.
Initially catalogued as a planetary nebula, was later thought to be misclassified and considered to be either a reflection nebula (LBN 809), an H-II region, and even a galaxy (PGC 16765). However it has recently been rediscovered as a genuine planetary nebula. It has a size of 115x126 arc seconds and is predominantly OIII. The weaker Ha signal has a similar form to the OIII signal. However there's an odd small area of red nebulosity at the top left-hand corner. This is possibly some NII emission which would be captured by the 5nm bandwith of my Ha filter (the spectrum shows that NII is present).
Discovered by Czech astronomer Dr. Luboš Kohoutek in 1962 by visually examining the National Geographic Society-Palomar Observatory Sky Survey prints at the Astronomical Institute in Prague, Czech Republic
It has a mean surface brightness of 24.1 mag/arc sec.

PM1-333

Image Description and Details : PM1-333 is a small (70 arc seconds) planetary nebula in the constellation Cepheus. It was discovered by Andrea Preite-Martinez in 1988. I believe this to be the deepest, and highest resolution colour image of this target. The tiny blue progenitor star can just be made out dead centre of the image.
It lies within IC1396 where it appears as a small dot at the bottom left hand corner in J-P Metsavainio's excellent image https://1.bp.blogspot.com/-JEMi-QvpB0Q/XicHMRDQXbI/AAAAAAAARug/ECBNZGRTptwRSAOExQSKmmvCIZWz6niCACLcBGAsYHQ/s1600/IC1396Det.jpg

PM1-320

PM1-320 is a small planetary nebula in Cygnus, close to DWB 111, the Propeller Nebula.
It was discovered by Andrea Preite-Martinez in the 1980s.
I believe this to be the first deep high-resolution image of PM1-320.
The outer parts of the nebulosity are very faint, hence 56 hours of OIII integration.
HASH records it's size as 60 arc seconds.

Ngc 6772

Hartl-Dengel-Weinberger 3 (HDW 3)

Hartl-Dengel-Weinberger 3 (HDW 3) is an extremely faint ancient planetary nebula in the constellation Perseus. It is so faint that it is very rarely imaged.
The progenitor star is the small blue star at the 5 o-clock position just below the large yellow star in HDW 3. The progenitor is not, as one would expect, in the centre of the nebula. This is because it is moving rapidly in a north-westerly direction. It is moving through a dense area of interstellar medium (ISM). This ISM is slowing down HDW 3, creating a shock front and the unusual "braided" appearance. As the star isn't slowed by the ISM it has continued to move and is thus no longer at the centre of HDW 3 and is slowly overtaking HDW 3. This causes the shock front to be brighter as it's getting more ultraviolet radiation, whereas the opposite side of HDW 3 is getting less UV radiation and has become invisible. This movement of the star causes differential excitation of the shell. OIII emission, which requires higher energy of the ionizing radiation than HII emission, only happens close to the star.

EGB 4

EGB 4 (a nebula discovered by Ellis, Grayson, & Bond in 1984) is NOT a comet, despite it's comet-like appearance. It is an emission nebula surrounding a catacylismic binary star system called BZ Cam in the constellation of Camelopardis.

It has an unusual bow-shock structure as BZ Cam (with it's associated wind) moves through the interstellar medium, similar to the bow wave in front of a ship that is moving through water.

BZ Cam is believed to be a white dwarf star that is accreting mass from an accompanying main-sequence star of 0.3-0.4 solar masses.
It is around 2,500 light years away, and has a space velocity of 125 km/second.
I can only find one previous image of EGB 4 online, a NASA APOD from 2000, so I believe this could be the first amateaur image and thefirst colour image.
Yes it's incredibly faint!
