Galaxies of our Universe

Ok...of course anyone can say this now...but I always knew galaxies formed around black holes. It always seemed so obvious to me...what other mechanism could there be for these island universes to form out of the relative homegeneity of an inflating Universe? With each and every galaxy I image, I imagine the colossal power of the supernatural entity located at its center, and shudder with reverent awe and respect. Galaxies are also so damn far away...think about it...our current model of light implies the pictures you see here were made by photons of light that have travelled intact across the Universe for tens, perhaps hundreds of millions of years! Several thousand photons, spawn from the billions of stars within a galaxy millions of light years away and millions of years ago, survived this huge expanse of space only to be captured by my telescope and displayed for you here! How spectacular is that?

All images shown here were taken unguided, using a 10" LX200R at prime focus, unless otherwise specified. The focal reducer I occasionally do use is an OPTEC Lepus 0.62X.

Showcasing: NGC4216

NGC4216 - Cannibal Galaxy  by Terry Riopka
Designation: NGC4216
Alternate Name: Cannibal Galaxy
Constellation: Virgo
Imaging Date: June 1, 2014
Imaging Location: Concord
Exposure Time: 80 frames@20sec ~ 26.7min
ISO Setting: 1600
Imaging Device: Canon Rebel T3i
Optics LX200R 10" SCT
Focal Reducer: Optec Lepus 0.62X
Apparent Size: 8.1' x 1.8'
Comment: I took this more than two years ago, but decided to finally reprocess what I had and post it. 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!

Comment: Also known as NGC598, this rather large distended galaxy is about 3 million light years away. It was time to revisit this difficult subject. Combining two nights of images definitely improves this galaxy's look. I still can't seem to get a good amount of red out of it though. Certainly better than my previous attempt!

Comment: Also known as "Seyfert's Sextet", only 4 of the 6 are truly interacting and about 190 million light years distant. The fifth (small, center) is a background galaxy almost 5 times further away, while the sixth (top, vertically elongated) is actually a "tidal tail" of stars torn from one of the galaxies. The four should coalesce billions of years from now into a single large elliptical galaxy. The galaxies range in magnitude from 14.7 to 16.8 and quite small, making them challenging to photograph. However, good focus even brought out some true color out of this beautiful but small cluster of colliding galaxies! How spectacular is that?

Comment: There's a good reason why this is called the "Sunflower Galaxy". 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.

Comment: My third attempt at the spectacular edge-on galaxy in Andromeda. Focus looks dead-on, producing nice detail in the dust regions of the galaxy. You can clearly see numerous small tendrils in the central regions. The extra half hour compared to my previous attempt definitely reduced the noise, but the benefits of the improved focus are also noticeable. 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 MilkyWay!

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: M31
Alternate Name: Andromeda Galaxy
Constellation: Andromeda
Imaging Date: September 10, 2012
Imaging Location: Concord
Exposure Time: 94 frames@30sec ~ 47.0min
ISO Setting: 1600
Imaging Device: Canon Rebel T3i
Optics 300mm Telephoto
Focal Reducer: NA
Apparent Size: 190' x 60'
Comment: This is how Andromeda looked through the eyes of an 8 year old - just like I remembered it! But... taken by the 200 inch Hale telescope!
Designation: M99
Alternate Name: Spiral Galaxy
Constellation: Coma Berenices
Imaging Date: May 7, 2014
Imaging Location: Concord
Exposure Time: 80 frames@20sec ~ 26.7min
ISO Setting: 1600
Imaging Device: Canon Rebel T3i
Optics LX200R 10" SCT
Focal Reducer: Optec Lepus 0.62X
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.

ISO Setting: 1600
Imaging Device: Canon Rebel T3i
Optics LX200R 10" SCT
Focal Reducer: Optec Lepus 0.62X
Designation: M101
Alternate Name: Pinwheel Galaxy
Constellation: Ursa Major
Imaging Date: July 9, 2012
Imaging Location: Concord
Exposure Time: 57 frames@30sec ~ 28.5min
ISO Setting: 3200
Imaging Device: Canon Rebel T3i
Optics LX200R 10" SCT
Focal Reducer: Optec Lepus 0.62X
Apparent Size: 29' x 27'
Comment: My first deep sky photo taken over two different nights. This was also the first time I used a Bahtinov mask for fine tuning focus. I cannot tell you how much simpler and elegant it is to use this very simple device to improve imaging focus. It really *is* easy to use and DSS will never give you problems again!
Designation: M65-M66
Alternate Name: Part of Leo Triplet
Constellation: Leo
Imaging Date: April 17, 2013
Imaging Location: Concord
Exposure Time: 84 frames@20sec ~ 28.0min
ISO Setting: 3200
Imaging Device: Canon Rebel T3i
Optics LX200R 10" SCT
Focal Reducer: Optec Lepus 0.62X
Apparent Size: 8.7' x 2.5' / 9.1' x 4.2'
Comment: I love the textured detail visible here - both galaxies just barely fitting in the field of view of my focal reducer.
