Quote This night it was really windy so managing to photograph thru the 12" LX200 was almost impossible as any wind would make the images blurry. Out of a few hours integration time only around 20 minutes worth of data was usable. Even with that fact, the whirlpool galaxy turned out great. The last try was over three hours worth of data but with a smaller telescope, so the image scale was a lot better with this one. See more information here for the night this picture was taken. Quote

FactsA galaxy is a massive, gravitationally bound system consisting of stars, stellar remnants, an interstellar medium of gas and dust, and dark matter. Examples of galaxies range from dwarfs with as few as ten million stars to giants with one hundred trillion stars, each orbiting their galaxy's own center of mass.Factssource and more information wikipedia
