I'm usually no fan of Hubble palette pictures, but I love the mapped colors that are used here.

I find the picture exquisite.

Thanks a lot Ann for your comments
FYI, a have made a small update of the shown picture, just tried to reveal more details in the corners of the shown M42 center picture,

NGC281 - A Bloody-Toothed Pacman
Image copyright: Jason Guenzel

Urged by a friend, I've updated the title for this image. This Pacman Nebula is set apart by the use of near infrared (NIR) data blended into the red channel. This creates a "bloody tooth" so to speak, in the Pacman's mouth. I'm really not sure what creates this hotspot that is isolated to the infrared channel, but I can only guess it's pointing toward a young, energetic star or cluster obscured from our view.

This blend is a NIRSHO palette, mixing NIR and SII to red, Ha to green, and OIII to blue. The image came out extremely detailed, in part due to the great color contrast of this palette.

More detail and higher res image (please check it out!) can be seen at the Astrobin link....

CTB1 - ”Supernova Remnant”

Copyright: Mark Hanson
Description by “Sakib Rasool”

Spanning an area of 35 arcminutes on the sky towards the constellation of Cassiopeia, this enigmatic loop of ionized nebulosity is a supernova remnant catalogued as CTB 1. This name denotes it as a radio source compiled in the Caltech Observatory list B catalogue of 110 radio sources discovered in a radio survey in 1960. A few other CTB sources also correspond with a supernova remnant such as CTB 80.

The radio source CTB 1 was suspected to be a supernova remnant in 1960 and confirmed as a supernova remnant in 1971. Optical emission associated with it was discovered by Sidney van den Bergh in 1973. The optical structure consists of a roughly circular shell with a breakout rupture towards the north, which also coincides with a break in the radio shell at this location. This is likely to be the result of the supernova remnant's interaction with a nearby cavity of neutral hydrogen gas. The Ha shell is composed of multiple interlocking limb brightened filaments with faint emission also extending beyond the main shell towards the south. The OIII structure consists of a series of filaments forming a curved arc towards one side. Close inspection also reveals a small dark globule silhouetted against the southern part.

CTB 1 belongs to the morphological class of mixed-morphology supernova remnants, which consist of a radio shell with central x-ray emission. Other prominent examples of this class include IC 443 and W28. At a distance of 10,000 light years, the diameter of CTB 1 is 100 light years. The expansion of the shell in a highly dynamic environment suggests that the progenitor star that exploded to form the supernova remnant might have been a B or O-type supergiant star. The age of CTB 1 has many estimates but the most commonly accepted one is 10,000 years.

Interestingly this object has been considered erroneously as a planetary nebula and is catalogued as Abell 85 in George Abell's second version of the Abell planetary nebula catalogue published in 1966 and was also included in the first version published in 1955. It is also wrongly catalogued as a HII region in Beverley Lynd's amusingly named 1965 catalogue of bright nebulae as LBN 576.

The Hidden Galaxy (IC 342). KG Observatory, Julian CA.

IC 342 is a challenging target. Although it's bright, the galaxy sits near the equator of the Milky Way's galactic disk, where the sky is thick with glowing cosmic gas, bright stars, and dark, obscuring dust.

In order to see the intricate spiral structure of IC 342, you must gaze through a large amount of material contained within our own galaxy—no easy feat! As a result IC 342 is relatively difficult to spot and image, giving rise to its intriguing nickname: the "Hidden Galaxy."

Located very close to the Milky Way at 10.7 million light years distant from Earth, this sweeping spiral galaxy would be among the brightest in the sky were it not for its dust-obscured location. The galaxy is very active, as indicated by the range of colors.

A beautiful mixture of hot, blue star-forming regions, redder, cooler regions of gas, and dark lanes of opaque dust can be seen, all swirling together around a bright core. In 2003, astronomers confirmed this core to be a specific type of central region known as an HII nucleus—a name that indicates the presence of ionized hydrogen—that is likely to be creating many hot new stars.

Comet 46p/Wirtanen

It is showing a very big coma, almost pinpoint nucleus and a tiny tail already.
It is moving so slowly that I only stacked the stars and the comet showed allrigh (ok, slight color separation, but meh)
