Explanation: At the down right, large spiral galaxy NGC 1055 joins spiral Messier 77 in this sharp cosmic view toward the aquatic constellation Cetus. The narrowed, dusty appearance of edge-on spiral NGC 1055 contrasts nicely with the face-on view of M77's bright nucleus and spiral arms. Both over 100,000 light-years across, the pair are dominant members of a small galaxy group about 60 million light-years away. At that estimated distance, M77 is one of the most remote objects in Charles Messier's catalog and is separated from fellow island universe NGC 1055 by at least 500,000 light-years. The field of view is about the size of the full Moon on the sky and includes colorful foreground Milky Way stars (with diffraction spikes) along with more distant background galaxies.

NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus. The galaxy has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge. Discovered on December 19, 1783 by William Herschel from his home in Slough England.

Just outside this field is a super bright blue star, Delta Ceti, with a magnitude of 4.06. This star basically cast a bright glow over half the frame, creating terrific gradients that beat me. So I cropped the image down to

NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus. It has a percular dark lane of dust and gas that appears to be elevated above the galaxy's plane, almost blending away from the central plane. If you look carefully, several bright Ha areas can be easily seen.
The galaxy is fairly small in my instrument as it is only has an apparent size of 7'.6 × 2'.7 arc min. NGC 155 is 52 million light years away, and has a diameter of about 115,800 light years across. The apparent size is 7.6 X 2.7 arc min with an apparent magnitude of 11.4. It’s a fairly dramatic looking galaxy with an incrediable glow around it.
Now for the inner geek stuff. The guiding is performed with a SBIG Remote guide head. It may be old, by it’s really a nice bit of kit having its own shutter and TEC cooler. The chip measures 4.86 X 3.66 mm in size, giving it a field of view of 7.31 by 5.5 arc minutes. Normally I struggle to find a guide star to place on the guide chip. So, it’s fairly small, but in this case, the galaxy presented would fit diagonally on the guide chip. Hopefully, this helps to convey the size of this galaxy shown above. It's so cool to think that this galaxy would just squeeze onto the guide chip of this rig. :)

My last image with my set up thus not able to give it the time it deserved.
NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus. The galaxy has a prominent nuclear bulge crossed by a wide knotty dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge. Discovered on December 19, 1783 by William Herschel.
A rough distance estimate for NGC 1055 is 52 million light-years, with a diameter of about 115,800 light-years. NGC 1055 has extremely active star formation and is a bright infrared and radio source.
It is in a binary galaxy system with neighboring M77 (previously imaged) and there is about 7 million light years between them. Unfortunately I could not quite get both galaxies in the same image field!

This image contains three interesting targets. The first two are the larger galaxies in the foreground, NGC 1055 (lower left), and NGC 1068 or Messier 77 (upper right). The third is a little harder to spot. Zoom in on the galaxy in the upper right. If you are familiar with M77, there is what appears to be a little star where no star was before. It’s near the core, at the six o’clock position. That new star like object is Supernova SN 2018ivc. If you are having difficulty spotting it, I constructed an animated gif that highlights the event. Click on the image to zoom in. www.astrobin.com/379580/?nc=user and you will see it blinking in the animation.
The top right galaxy has two names, Messier 77 or NGC 1068. It’s a barred spiral galaxy in the constellation Cetus, about 47 million light years away. Messier 77 has an estimated diameter of 170,000 light years and is one of the biggest galaxies of the Messier Catalogue. The apparent size when viewed from our vantage point is 7.1 X 6.0 arc min with an apparent magnitude of 9.6
The galaxy in the lower left is NGC 1055. This is an edge-on spiral galaxy located in the same constellation, Cetus. It has a prominent bulge crossed by a wide knotty dark dust lane. If you look carefully, several bright Ha areas can be easily seen. NGC 155 is 52 million light years away, and has a diameter of about 115,800 light years across. The apparent size is 7.6 X 2.7 arc min with an apparent magnitude of 11.4. It’s a fairly dramatic look galaxy, and the glow around it is just amazing. I really like the look of this galaxy.
Messier 77 and NGC 1044 are a binary system. Because of this, I really wanted to include both objects in the same frame. Normally, I would image each separately.
The third object is the Supernova SN 2018ivc. The event happened midway during the imaging of this photo. At first, I thought it was my eyes or a guiding error. As I got more data, yep, something had changed. Once I realised this, I then heard about it. It only took 47 million years to get to us. What’s a few days to realize what you are looking at? If you’re interested in further information about the Supernova, there is a web page. www.rochesterastronomy.org/sn2018/sn2018ivc.html

M77 (right) and NGC1055 (left). Couple of spiral Galaxy located in the constellation Cetus
This is a 10 hour exposure of the NGC1055 galaxy from my backyard using a standard Canon 40D DSLR. The image is taken with a Celestron 8" SCT at F10 (2032mm focal length).
The image consists of mostly 600s subs and approximately 2 hours of 90-150s subs, all at ISO 800.
This galaxy is located at about 60 Million Light years distance from us, and at a magnitude of 12.5 is quite a faint object to image, especially when there is a little bit of light pollution with in the par of the sky it is imaged at... Looking at the result, I probably should have used the f6.3 FR to have less over sampling and most likely capturing more light in the same amount of time, or same amount in less time... end result most probably, at worst, would have been the same if not very similar and at best there might have been a bit more detail captured since guiding at 63% of the focal length and not oversamplig the subs would not be as susceptible to seeing/star fluctuations/movement.

NGC 1055 is a magnitude 11.4, edge-on spiral galaxy in the constellation Cetus.
The distance to this galaxy is estimated to be about 52 million light years.
Imaged using a 8" SCT at f6.3 (1280mm focal length), with a QHY268M camera for a total integration time of 9 hours and 05 minutes.
NGC 1055 is the edge-on spiral galaxy located in the left of this image. It is estimated to be 52 million light years away. It was discovered in 1783 by William Herschel.
M77 is the barred spiral galaxy on the right. It is about 47 million light years away. It was discovered in 1780 by Pierre Mechain and later added as number 77 to Charles Messiers' catalog of "not a comet" objects.

The Messier galaxy (M77) is often visited by amateur astronomers. Few realize that M77 shares a system of at least seven galaxies with the equally large spiral galaxy, NGC 1055. These two large galaxies are only separated by 442,000 light years making them much closer than the Milky Way and the Andromeda Galaxy are within our own local galaxy group. All the other galaxies within the M77/NGC 1055 system are far smaller and not within reach of my backyard telescope.
NGC 1055 is located less than half-degree from M77. It is a slightly more difficult target in the telescope than M77 since it is seen nearly edge on from our line-of-sight. Still, I do not find it overly difficult to find, on a good night, from my house deck with the 155mm refractor.
Since NGC 1055 is a galaxy that is listed in the Herschel 400, you might as well take-a-look at it while visiting M77.

M77 (NGC 1068, at the bottom left) is a galaxy with an active nucleus. The supermassive black hole at its center is actively feeding. This, and other characteristics, make it a Seyfert galaxy. NGC 1055 (at the top right) is another spiral galaxy seen edge-on with a thick dust lane across its equator. NGC 1072 is the small spiral at the far left edge of the picture.
This was shot entirely from my light polluted backyard in Long Beach, CA. It is a combination of 17 5 minute RGB subframes from an Atik 314L+ with a light pollution filter and 16 5 minute H-alpha subframes from an Atik 414-EX. All shot with a Celestron Edge HD 925 at f/2.3 with Hyperstar. Preprocessing in Nebulosity, most processing in PixInsight, and a fight with some pretty bad gradients in Photoshop.
I will revisit this and take more data to try to smooth that diffuse cloud around M77.

In addition to being a magnificent spiral galaxy, M77 (left) is famous for having a very active nucleus (Seyfert galaxy). It is now established that a huge black hole hole is its center is swallowing great quantities of matter and is emitting powerful radiation in this process.

Pareidolia, a word to describe seeing familiar objects or patterns in otherwise random or unrelated objects. Like animal shapes in clouds. Here I see a face, but not a happy one. In reality, the mouth is a galaxy unimaginably more distant than all of the stars in this image which belong to our own galaxy. And science tells us that the colour of a star is linked to its surface temperature, blue being much hotter than yellow.

Galactic treat! Edge-on galaxy NGC 1055 with a fabulous dust lane and tenuous stellar cloud rising above and below. This galaxy is approximately 52-million light years away. Juxtaposed in the field is Messier galaxy #77 seen face-on from top (or bottom since space has no up or down). This galaxy is 47 million light years distant. This deep image contains 5.6 hours of data and revels some extremely faint (distant) galaxies. Follow the edge-on galaxy's dust lane left to the edge of the frame and find the tiny galaxy dot. This is PGC10146 and it is estimated to be 637 million light years from earth. This means we are seeing it as it appeared when the first multi-celled creatures appeared on Earth during the PreCambrian era. How's that!

M77 Region - 7 Hours of integration in the backyard under mixed skies - mostly with the waxing moon nearby. Humidity was high, dew was everywhere.
First night used the Baader Moon and Skyglow filter. Two other nights used the IDAS LPR filter. Sky background is a muddy brown because of the nearby sodium lights.
Total subs used: 42 at 10 minutes at 400 ISO.
Calibrated with Maxim DL with master files based on 256 bias and 35 flats with temperature matched darks. I'd report the exact number of darks used, but I calibrated at different times and didn't keep notes. Suffice to say it's more than 50.
Stacked in DSS 3.3.3 beta 47. I've noticed that when stacking in other than mosiac mode, DSS tends to enhance the gradients significantly. Because there were framing issues from the successive nights, there is only a small section of the mosaic that is good. Still, it's interesting to see what galaxies popped out of the background.
Processed in PI: cropped, DBE, masked stretch script, scnr, mask made of the L channel and stretched, this mask was used repeatedly as a positive and negative for: ATrous, Deconvolution, curves (for saturation), and histogram stretch.
Once I exported this, I did not modify it in LR3. I'm happy enough with how it looks.
I think I finally understand how to use Atrous a bit more. An important thing to do was apply it on the Chrominance and Lumincance separately and avoid applying it to RGB.
I've also done some reading in Berry & Burnell's Handbook of Astronomical Image Processing regarding using deconvolution. Thus, I was better able to understand how some of the settings work there.
I'm still ham-fisted, but it's coming along.

Description:
M77 is a barred spiral galaxy, with quite a set of spiral arms. It was thought to be a star cluster when discovered about 1780 by Mechain and added to Messier's catalog. Later reclassified as a spiral galaxy with tightly wound arms. Finally, infrared images of the inner part of the galaxy reveal a prominent bar not seen in visual light, and for this reason it is now considered a barred spiral.
M77 is a prime example of a Seyfert galaxy, or a galaxy with an intensely active center that is obscured by gas and dust in visible light.
One cool and very recent fact: In November 2022, the IceCube collaboration announced the detection of a neutrino source emitted by the active galactic nucleus of Messier 77. This is only the 4th known source of neutrinos, including our Sun.
NGC 1055 is an edge-on galaxy. It has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. It is slightly larger than our Milky Way galaxy, 100,000 light years across.
NGC 1055 has a boxy halo that extends far above and below the central bluge and disk of NGC 1055. The halo itself is laced with faint, narrow structures, and could represent the mixed and spread out debris from a satellite galaxy disrupted by the larger spiral some 10 billion years ago.
NGC 1055 and M77 form a binary galactic system. They are the largest galaxies of a small galactic cluster that includes 6 other galaxies. I read on Wikipedia that they are approximately 442,000 light years apart, but this must only the distance that they appear apart in an image, since NGC 1055 is about 7 Million light years farther from Earth than M77.

First night used the Baader Moon and Skyglow filter. Two other nights used the IDAS LPR filter. Sky background is a muddy brown because of the nearby sodium lights.
Total subs used: 42 at 10 minutes at 400 ISO.
Calibrated with Maxim DL with master files based on 256 bias and 35 flats with temperature matched darks. I'd report the exact number of darks used, but I calibrated at different times and didn't keep notes. Suffice to say it's more than 50.
Stacked in DSS 3.3.3 beta 47. I've noticed that when stacking in other than mosiac mode, DSS tends to enhance the gradients significantly. Because there were framing issues from the successive nights, there is only a small section of the mosaic that is good. Still, it's interesting to see what galaxies popped out of the background.
Processed in PI: cropped, DBE, masked stretch script, scnr, mask made of the L channel and stretched, this mask was used repeatedly as a positive and negative for: ATrous, Deconvolution, curves (for saturation), and histogram stretch.
Once I exported this, I did not modify it in LR3. I'm happy enough with how it looks.
I think I finally understand how to use Atrous a bit more. An important thing to do was apply it on the Chrominance and Lumincance separately and avoid applying it to RGB.
I've also done some reading in Berry & Burnell's Handbook of Astronomical Image Processing regarding using deconvolution. Thus, I was better able to understand how some of the settings work there.
I'm still ham-fisted, but it's coming along.
M77, also known as NGC 1068 or the Squid Galaxy, is a barred spiral galaxy in the constellation Cetus at about 47 million light-years. In the bottom left we find NGC 1055 at a distance of 52 million light-years, with a diameter of about 115000 light-years. The separation between NGC 1055 and M77 is about 7 million light-years. Other galaxies in this field of view are NGC 1087 (top right) and NGC 1090 at distances of 80 and 124 million light-years. This image was recorded in 12.5 hours at my remote observatory in Hakos-Namibia with a SW Esprit 120ED , ZWO ASI2600MC camera on a 10 Micron 2000HPS mount

Upper right lies Messier 77 (M77), also known as NGC 1068 or the Squid Galaxy, it is a barred spiral galaxy in the constellation Cetus. It is about 47 million light-years away from Earth. Messier 77 was discovered by Pierre Méchain in 1780, who originally described it as a nebula. Méchain then communicated his discovery to Charles Messier, who subsequently listed the object in his catalog. Both Messier and William Herschel described this galaxy as a star cluster.[8] Today, however, the object is known to be a galaxy.
Lower down at a distance of 52 million light years is the edge on spiral galaxy NGC1055. This galaxy has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge. Discovered on December 19, 1783 by William Herschel from his home in Slough England.
Both of these galaxies form a binary system.
Littered around the background are a large number of very small and much more distant galaxies.
Shining brightly is the +4 magnitude star Delta Ceti, at a much closer 650 million light years. It is also a beta Cephei Variable with a cycle of around .16 days and is around 4000 times the luminosity of our sun.

Edited European Southern Observatory image of the edge-on galaxy NGC 1055. (I lost my original image so all images are color/processing variants).
This colourful image from ESO’s Very Large Telescope shows NGC 1055 in the constellation of Cetus (The Sea Monster). This large galaxy is thought to be up to 15 percent larger in diameter than the Milky Way. NGC 1055 appears to lack the whirling arms characteristic of a spiral, as it is seen edge-on. However, it displays odd twists in its structure that were probably caused by an interaction with a large neighbouring galaxy.
