Designation: NGC3628 Alternate Name: Sarah's Galaxy Constellation: Leo Imaging Date: May 10, 2023 Imaging Location: Concord Exposure Time: 68 frames@300sec ~ 5.7hrs Gain Setting: 200 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 15' x 3.6' Comment: This is an unbarred spiral galaxy about 35 million light years away, part of the Leo triplet. The fuzzy blob in the center just above it is a satellite galaxy. Of note is that the FOV associated with it is ideal for Pixinsight processing with stars removed and then added back in. There isn't a very large variance in star size, enabling StarNet++ to successfully extract them all, leaving minimal artifacts.I don't often use that method, but it worked well in this case. Otherwise I used my typical workflow: DBE, PCC, BXT, EzDenoise, EzSoftStretch, remove stars, enhance, then return them and do minor touch ups. Here's my previous 28min exposure oh some many years ago with my 10inch and T3i DSLR. |

Of course, with my 10 inch, I only hinted at the other two companions! Here's my previous version. Fascinating edge-on galaxy roughly 55 million light years away, near the center of the Virgo cluster. It has almost five times the numnber of globular clusters in our galaxy and has stellar streams connected to two satellite galaxies it appears to be disrupting. There are multiple galaxies visible in this image including most prominently NGC4222 below. There seems to be a great deal of galactic activity in the Virgo cluster, and this galaxy is near the center of it all! |

This galaxy apparently has more than twice the number of globular clusters in our galaxy. The key to imaging in this case seems to be not so much longer exposure as it is good focus, good tracking and steady atmosphere, all of which could probably stand for some improvement. Here's my previous attempt with my 10 inch under fairly good conditions. Interestingly, on trying to reconcile the apparently different detail I was seeing in my two attempts, I realized my 10inch attempt actually only images the central part of the galaxy, while the newer attempt extends the edges of the galaxy about twice the distance out! |
Designation: NGC672,IC1727 Alternate Name: Interacting Pair of Galaxies Constellation: Triangulum Imaging Date: December 10, 2020 Imaging Location: Concord Exposure Time: 101 frames@180sec ~ 5.1hrs Gain Setting: 0 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 6.2' x 2.3' / 6.5' x 2.4' Comment: NGC672 is a spiral galaxy interacting with a dwarf galaxy called IC1727. The pair is located about 23 million light years away and is thought to be part of a cluster of dwarf galaxies formed along a filament of intergalactic gas accreted on a dark matter "backbone". Methods to detect that intergalactic gas are currently underway. The sensitivity of the ASI2600mc camera is notable in this 5 hour exposure, revealing nice structure in the larger pair of galaxies but also bringing out multiple edge on galaxies in the field as well, in addition to several "fuzzies" around NGC672 itself. There's no way I could have gotten this much detail using my DSLR! |

Designation: NGC891 Alternate Name: Dark Star Galaxy Constellation: Andromeda Imaging Date: September 19, 2020 Imaging Location: Concord Exposure Time: 154 frames@120sec ~ 5.1hrs Gain Setting: ISO 1600 Imaging Device: Canon Rebel T3i Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 12.0' x 1.0' Comment: NGC891 is a beautiful example of an edge-on galaxy, about 30 million light years away in Andromeda. Apparently this galaxy is very similar to what our galaxy would look like seen edge-on. You can see glimpses of that yourself on very dark summer nights looking into the center of the Milky Way! Its many filaments and tendrils extending out of its plane are thought to be the result of the ejection of material due to supernovae and intense stellar formation activity. In the upper left part of the image, right under NGC891, you can also see a tiny image of a distant spiral galaxy in the background. Upping the aperture and exposure time really does bring out some nice detail! Here are my previous attempts at 20 minutes and 52 minutes exposure time, both with my 10 inch. |
Designation: NGC3077 Alternate Name: Dwarf Galaxy Constellation: UrsaMajor Imaging Date: April 22, 2022 Imaging Location: Concord Exposure Time: 118 frames@180sec ~ 5.9hrs Gain Setting: 200 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 5.4' x 4.5' Comment: NGC3077 is also a starburst dwarf galaxy just a little further at 12 million light years. Its disrupted structure suggests some sort of galaxy interaction in its past. Its young star bluish core has a small inner disk of older stars visible as a small reddish peanut shaped object in the galaxy's center. What a stunninglittle galaxy! |
Designation: M95 Alternate Name: Barred Spiral Galaxy Constellation: Leo Imaging Date: April 20, 2022 Imaging Location: Concord Exposure Time: 170 frames@180sec ~ 8.5hrs Gain Setting: 200 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 3.1' x 2.9' Comment: Home of the Green Lantern? Difficult barred spiral, but nice ring like structure. Even with more than 8h of exposure, it could still use more to get the arms to come out with more contrast. My first attempt with my 10 inchoh so many years ago did not do it justice. |

I may have pushed the color a little too much in my processing, and may eventually revisit that process. However, the detail in this version of M81 came out spectacularly well using my ASI2600mc on my 12 inch, no comparison to my previous much shorter exposure using my 10 inch. Its satellite galaxy, Holmberg IX, is an irregular dwarf galaxy, faintly visible here to the right of the main galaxy. I thought it was a smudge from a bad set of flats at first! |

Mousing over the image displays an annotation that labels the galaxies of the group. The largest of them, NGC1961 is about 200 million light years from Earth and likely over 200,000 light years in diameter! There are competing theories about the galaxy NGC1961 shown in a closesup here. Based on mass calculations, it is either a massive disc galaxy with a huge, even more massive halo (not visible), or, it's a coincidental interloper encroaching on the group, *and* there's a massive amount of unseen matter stabalizing the cluster. |

It is a prototype for class of galaxies called "flocculent galaxies" whose arms are patchy and discontinous. Its nucleus orbits in the opposite direction to its outer rim, suggesting some sort of interaction with another galaxy in its distant past. |
Designation: M33 Alternate Name: Pinwheel Galaxy Constellation: Triangulum Imaging Date: November 18, 2020 Imaging Location: Concord Exposure Time: 98 frames@180sec ~ 4.9hrs Gain Setting: 0 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 71' x 42' Comment: Also known as NGC598, this rather large distended galaxy is about 3 million light years away. This galaxy has some beautiful color to it, and you don't need an Halpha filter to get to it. This was taken using RGB only, with some restrained color saturation to boost the "natural" colors. Inevitably, you hear astroimagers combining Halpha images with RGB, but the bottom line is that *all* that information is there already - you just need a long enough exposure and a reweighting of the color to show it. Here are my two previous attempts at 7 minutes and 53 minutes exposure time with my T3i on my 10 inch. |
Designation: NGC7814 Alternate Name: Little Sombrero Galaxy Constellation: Pegasus Imaging Date: November 10, 2014 Imaging Location: Concord Exposure Time: 80 frames@20sec ~ 26.7min Gain Setting: ISO 1600 Imaging Device: Canon Rebel T3i Optics: LX200R 10" SCT Focal Reducer: Optec Lepus 0.62X Filter: none Apparent Size: 5.5' x 2.3' Comment: Nice edge-on galaxy with a strong dust lane, about the same physical size as M104 and about 40 million light years distant.

You can see beautiful short spiral arm segments around the entire periphery of the galaxy. Recently, evidence has been found of faint, giant arc-loop features in the halo of the galaxy hypothesized to be the remnants of a disrupted dwarf satellite galaxy. |

M96 is the brightest galaxy in the M96 Group in Leo, and at magnitude 10.1, is about 35 million light years away. Variations in ultraviolet emission from the core suggest the presence of a supermassive black hole. |
Designation: NGC3521 Alternate Name: B bble Galaxy Constellation: Leo Imaging Date: May 14, 2021 Imaging Location: Concord Exposure Time: 120 frames@180sec ~ 6.0hrs Gain Setting: 100 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 11.0' x 5.1' Comment: This is a spiral galaxy in Leo known for its extended halos of gas, thought to be caused by multiple mergers of it with its various satellite galaxies in the past. I like the fact that I'm able to image more background galaxies due to my much longer exposures. The detail is also decent, making visible many small pink splotches of hydrogen-alpha nebulae scattered throughout, corresponding to star forming regions in the galaxy. The galaxy has been measured to be approximately 35 million light years distant. |

The galaxy also has a water vapour megamaser, the source of its purplish hue. This was my first serious go with PixInsight! As you can see, the results truly are astounding, I must say. Of course the 4 hour exposure with a 12 inch also helped :). There is no comparison to my previous 26 minute exposure! |

It has a large population of H II star forming regions, many large enough to have their own NGC catalog numbers. If you mouseover the image, you can see an annotated version overlay with the labeled regions. About nine years ago, this was a milestone image for me - the first deep sky photo I took over two different nights and the first time I used a Bahtinov mask for fine tuning focus - a method I still prefer to automatic focus! Here it is for posterity :) - a 29min exposure using my 10 inch and Canon T3i. |
Designation: NGC5982 Alternate Name: Draco Galaxy Trio Constellation: Draco Imaging Date: April 10, 2022 Imaging Location: Concord Exposure Time: 156 frames@180sec ~ 7.8hrs Gain Setting: 200 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 3.3' x 0.8' / 3.0' x 2.1' / 5.5' x 2.5' Comment: Left to right are NGC5981, NGC5982 and NGC5985 referred to as the Draco Galaxy Trio. I'm surprised this trio of galaxies isn't imaged more often. It's a beautiful arrangement with a multitude of other small galaxies in the background. |
Designation: M51 Alternate Name: Whirlpool Galaxy Constellation: Canes Venati i Imaging Date: March 21, 2014 Imaging Location: Concord Exposure Time: 160 frames@20sec ~ 53.3min Gain Setting: ISO 1600 Imaging Device: Canon Rebel T3i Optics: LX200R 10" SCT Focal Reducer: Optec Lepus 0.62X Filter: none Apparent Size: 11.2' x 6.9' Comment: My seventh! attempt at this beautiful double galaxy. This time I combined two nights, one using ISO1600, the other ISO3200 from the previous year. I know you're not supposed to mix ISOs but that's all I had and results weren't horrible. The color's better, focus is good, but the noise is still too high - both times I also had a Moon in the sky, so conditions weren't optimal. I need longer exposures and darker skies! |

Designation: M99 Alternate Name: Spiral Galaxy Constellation: Coma Bereni es Imaging Date: May 7, 2014 Imaging Location: Concord Exposure Time: 80 frames@20sec ~ 26.7min Gain Setting: ISO 1600 Imaging Device: Canon Rebel T3i Optics: LX200R 10" SCT Focal Reducer: Optec Lepus 0.62X Filter: none Apparent Size: 5.4' x 4.7' Comment: Nice little face-on spiral with significant mottled structure. It's amazing that the spiral arms show up even in a single 20 sec exposure. |
Designation: M65-M66 Alternate Name: Part of Leo Triplet Constellation: Leo Imaging Date: February 11, 2023 Imaging Location: Concord Exposure Time: 111 frames@180sec ~ 5.6hrs Gain Setting: 200 Imaging Device: ZWO ASI2600 Optics: Classic LX200 12" SCT Focal Reducer: Meade Series 4000 f/6.3 Filter: none Apparent Size: 8.7' x 2.5' / 9.1' x 4.2' Comment: Nice extended cloud detail in M66. I love the textured detail visible here - both galaxies just barely fitting in the field of view of my focal reducer. Here's my previous 28min exposure oh some many years ago with my 10inch and T3i DSLR. |
Designation: NGC5746,5740 Alternate Name: Blade and Pearl Galaxy Constellation: Virgo Imaging Date: June 1, 2014 Imaging Location: Concord Exposure Time: 80 frames@20sec ~ 26.7min Gain Setting: ISO 1600 Imaging Device: Canon Rebel T3i Optics: LX200R 10" SCT Focal Reducer: Optec Lepus 0.62X Filter: none Apparent Size: 7.4'x 1' / 2.6'x 1.3' Comment: These definitely look better together than separately! |
