NGC 4051 is a spiral Sifert galaxy in the constellation Ursa Major, at about 48 Mly from earth. It covers about 5 x 4 arcminutes of the night sky The core of this galaxy contains a supermassive black hole.

Data from the Liverpool Telescope, La Palma (2 m aperture and 0.28 "/pixel resolution)

      A very crisp and cold night.  I added more luminance data and also collected some RGB for NGC 2841. There is now around 4 hours in L and an hour each in R, G and B. The subs are 114s at a gain of 139. 
       
       

       
      Wikipedia:
      NGC 2841 is an unbarred spiral galaxy in the northern circumpolar constellation of Ursa Major. A 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined its distance to be approximately 14.1 megaparsecs or 46 million light-years. 
      This is the prototype for the flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous. The morphological class is SAa, indicating a spiral galaxy with no central bar and very tightly-wound arms. There is no grand design structure visible in the optical band, although some inner spiral arms can be seen in the near infrared. 
      The properties of NGC 2841 are similar to those of the Andromeda Galaxy. It is home to a large population of young blue stars, and a few H II regions. The luminosity of the galaxy is 2×1010 M☉ and it has a combined mass of 7×1010 M☉. Its disk of stars can be traced out to a radius of around 228 kly (70 kpc). This disk begins to warp at a radius of around 98 kly (30 kpc), suggesting the perturbing effect of in-falling matter from the surrounding medium.
      The rotational behaviour of the galaxy suggests there is a massive nuclear bulge, with a low-ionization nuclear emission-line region  at the core; a type of region that is characterized by spectral line emission from weakly ionized atoms. A prominent molecular ring is orbiting at a radius of 7–20 kly (2–6 kpc), which is providing a star-forming region of gas and dust. The nucleus appears decoupled and there is a counter-rotating element of stars and gas in the outer parts of the nucleus, suggesting a recent interaction with a smaller galaxy.

      So I was out the other night collecting images for a star trails of Ursa Major over the top of my daughter's tree in the front garden. Out of curiosity more than anything, I thought I'd give time lapse a shot. The attached is low res as I'm still messing around with what codec etc works best. The original avi file was pushing 8gb for 7 seconds!! Managed to get it down to 22mb but can't find anything inbetween. I'll keep playing though.
      Original raw files cleaned up in Lightroom, then exported out as Jpg's into After Effects. The trails image used the same Jpg set but was put together in Star Stax. As pretty much first attempts at both, I'm happy.

      I have a question, imagine a Galaxy with a supermassive black hole smack in the middle, with a mass of a billion suns, devowering stars at an incredible rate and relatively growing as it consumes stars.
      A black hole that large in the center of our galaxy, “Sagittarius A” it’s location is believed to be, in the densest part of our galaxy (I mean concentration and proximity of stars) would be swallowing up stars at an enormous rate would it not?.
      Astronomers say it is possible that all, most, many? Galaxies have a supermassive black hole at their cores, let’s assume this is fact, eventually an entire galaxy can be consumed by a black hole that size. The more it consumes, the greater it’s gravitational pull, it eventually grows exponentially until the whole galaxy is snuffed out?.
      Having said that, there surely must be examples somewhere of galaxies in the process of being swallowed up, in their final death throws, the remnants of spiral arms and the few millions of stars left on their final plunge into blackness and infinite, invisible density. 
      Or,  supermassive black holes may well be a relatively new phase in a galaxies life cycle? are we living at the point where these gargantuan black holes are coming into existence, and maybe it will be billions of years more before galaxies begin to fall prey to their own black holes?. Are there any examples of galaxies much older than ours where evidence shows they are being consumed slowly?
      Something as massive, and destructive, as a black hole with a billion star mass, smack in the middle of a galaxies densest region must eventually become a runaway, growing exponentially and consume an entire galaxy, would it not?. Is it possible that our present stelliferous age will meet its end by way of ever expanding black holes?. 
      I would love to hear your thoughts!

      Hi, im Kez and have heaps of questions about a hypothesis I came up with hopeing some one will help with some of these and educate me a lot.
      What math would I nerd to learn to try to calculate the size of a black hole with a mass several times that of earth? 
      If a small black hole were stationary relative to the sun close to our solar system would the orbit of earth be likely to create an eclipse with a distant star and if so at what frequency and would current technology be able to conclusively measure an observation? Also what math do I need to figure this out? 
      Anyone know anyone doing work on this or if it was previously hypothesised? Disproved? 
      Anyone with anything that may educate me on this topic would be awesome and even general comments, thoughts, I'm a real noob but genuine interest in astrophysics, quantum physics heaps of stuff. Any knowledgeable contacts for discussion. Cheers!!!!
