Markarian's Chain is a prominent, gently curved stretch of galaxies situated near the heart of the Virgo Cluster, approximately 50 to 55 million light-years away toward the constellation Virgo. Dominated by massive giant elliptical galaxies like M84 and M86 alongside interacting galactic pairs like "The Eyes" (NGC 4435 and NGC 4438), this dense structure forms a dynamic gravitational laboratory driven by tidal interactions and ram-pressure stripping as galaxies plunge through the intracluster medium. Deep narrowband and broadband imaging ($\text{LHRGB}$) reveals intricate extra-galactic ionized gas structures, including tenuous Hydrogen-alpha ($\text{H}\alpha$) bridges spanning between member galaxies, energetic relativistic jets from supermassive black holes like that of nearby M87, and faint diffuse foreground clouds across the intergalactic field.

Image Description and Details : This is a region of space in Auriga showing a large and faint Supernova Remnant (Sh2-221) next an equally large and faint Planetary Nebula (Sh2-216). The latter is also often called the "Second Closest Planetary Nebula." The former may be an example of the earliest recorded supernova (~6600 years ago) as a cave drawing depicting this area of sky was found with a possible illustration of a bright light in the same area of sky, though this interpretation is not conclusive.

Altogether this field of view covers over a dozen times the apparent width of the Full Moon in our sky and was captured with a total of 44.5 hours across 9 nights of imaging (9 hours RGB, 36.5 hours evenly split between Hydrogen and Oxygen filters).

Image Description and Details :

LDN 673 (lower-left) is a swirling Dark Nebula located within the main band of the Milky Way in Aquila which takes on a tentacle-like appearance. Including the dark nebula LDN 684 in the upper-right, the entire complex appears much like the silhouette of a Reaper from the Mass Effect series. I shot this across 6 nights under the Bortle 1 skies of the 2021 Okie-Tex Star Party totaling 6 hours Luminance (full visible light spectrum for contrast) and 2.3 hours exposure for each Red, Green, and Blue channels. 350mm Focal Length Refractor, ASI1600MM-P, APT for capture, Pixinsight for processing

Image Description and Details :

This is part of the Taurus Molecular cloud complex apparently located about halfway between the Pleiades and Aldebaran and about ~430 l.y. from here. The shape of the nebula reminds me of a darker version of the Eagle Nebula's Pillars of Creation, leading to my title. Also captured, though only as 6 small smears, is a 70km-wide asteroid called 322 Phaeo (discovered 1891) which was moving through the area at the time. I shot this nebula was shot in Bortle 1 skies over 6 nights at the 2021 Okie-Tex Star Party in Western Oklahoma during early October 2021. Transparency throughout the week was mediocre so only 16 hours of a larger 26 hour total was used for stacking.
