This object has always been difficult for those of us who do EAA. Atik's brightness (mag. 3.85) makes it difficult to see the faint nebula IC 138.

NGC 578 has a fairly bright halo elongated 4' x 2' ESE-WNW fading rapidly toward the tips. The core is broad and just slightly brighter.

Being able to capture the two colors of this faint nebula with 15 seconds of exposure is my goal. For more detail, more exposure ... and guidance is needed.

NGC 1535 is a 9th magnitude planetary nebula in the constellation Eridanus. Located east of Zaurak, it is a nice diversion from all the galaxies in Eridanus. It has been nicknamed Cleopatra's Eye.

NGC 1637 is relatively bright. Its 3' x 2' NNE-SSW halo contains a circular core with a stellar nucleus. A 13th magnitude star lies 2' NE of the center.

The halo is unevenly bright with hints of spiral structure in the NE and SE portions. The core is moderately large but unevenly bright and has a stellar nucleus.

M 82, el Cigarro: Based on an original taken with an RGB camera, without tracking and with exposures of 25 seconds stacked 18 times. There are Darks and Flats applied.

After the basic workflow, I have used Fractal Flux / Sharp, with mask, to highlight the dark paths of the galaxy, I have applied Denoise twice with grain 6 and grain 3 to smooth out the background noise. The color treatment has been without a mask the first time and with a galaxy mask to touch up the final colors.
This is not a contest photography but Startools has taken something decent out of a noisy, low-exposure original, as usual at EAA.

Galaxies consist of a number of different structures, and the particulars of these structures drive the evolution of a given galaxy. One such structure in spiral galaxies like Caldwell 40 (or NGC 3626) is the galactic bulge. This structure is a densely packed region of stars that encompasses the heart of a spiral galaxy. Most galactic bulges host supermassive black holes, with the masses of the black hole and the bulge typically linked (bigger bulges harbor more monstrous black holes). NASA

As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.
