Image Description and Details :

Barred spiral NGC 5101 (top right) and nearly edge-on system NGC 5078 are separated on the sky by about 0.5 degrees or about the apparent width of a full moon. Found within the boundaries of the serpentine constellation Hydra, both are estimated to be around 90 million light-years away and similar in size to our own large Milky Way galaxy. In fact, if they both lie at the same distance their projected separation would be only 800,000 light-years or so. That's easily less than half the distance between the Milky Way and the Andromeda Galaxy. NGC 5078 is interacting with a smaller companion galaxy, cataloged as IC 879, seen just left of the larger galaxy's bright core. Even more distant background galaxies are scattered around the colorful field. Some are even visible right through the face-on disk of NGC 5101. But the prominent spiky stars are in the foreground, well within our own Milky Way.Location/Date – El Sauce, Chile, April 2021Imaging System – Planewave 17” CDK, 10 Micron GM3000, FLI ML16803 Chroma FiltersExposure – LRGB, 15.2 hoursProcessing – Pixinsight

Ced 51 is an interesting juxtaposition of dark and light, containing dense dark nebula in the foreground abs curing portions of the greater hydrogen nebula flowing in red. Right in the middle is an active star forming region birthing new bright blue stars. Part of the greater lambda orionis ring (head of orion), this nebula complex is approximately 5000 light years from earth in the constellation of Orion, the hunter.

Technically, this was a challenge as to do the area justice, we shot a 4 panel mosaic to frame it right.

Cederblad 111 (Ced 111) is a blue reflection region in the southern constellation of Chamaeleon and is part of one of the closest (~550 light years) dark cloud complexes to the Sun. Ced 110 is the bright reflection in the lower portion of the image with the distinct bright arc. Both are part of Cha I dark cloud complex. The median age is estimated at ~2 Myr. The cloud complex is a stellar nursery and many new stars have been detected through their variability and H-a emission. The small, elongated, bright red objects at the center of the image are Hebrig-Haro objects (HH 49-50), which form from a collision between ionized jets of gas ejected from newly born stars and the surrounding cloud.

Messier 100 (also known as NGC 4321) is a grand design intermediate spiral galaxy located within the southern part of constellation Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster, located approximately 55 million light-years[3] distant from Earth and has a diameter of 107,000 light years, roughly 60% the size of the Milky Way.
