NGC 5466 a globular cluster in the constellation Boötes. Located 51800 light years from earth. A fairly dim cluster at magnitude 9.There are a couple dim distant galaxies in the frame unknown what distance these are. My capture software (skyx pro) gives me a magnitude 17 for all of them, however I cannot find a distance. Exposure was during full moon. Exposure time was 7 hours. 4 hours Luminance 1 hour each RGB.

Messier 101 “Pinwheel Galaxy” a face on spiral galaxy in constellation Ursa Major 21 million light years away. Comparable in size to our milky way galaxy its diameter is an estimated 170,000 light years across. Notable for its high population of H II regions, many of which are very large and bright. Luminance layer from 8 inch RC telescope color and Ha mixed from 2 systems 6inch Newtonian and 8 inch RC. Fairly long exposure time on this most of it is in color from the 6 inch Newtonian.
Messier 51 commonly called the “Whirlpool Galaxy”. A beautiful example of an interacting grand design spiral galaxy. Located in the constellation Canes Venatici, M 51 is approx. 23 million light years away. Imaged here in natural colors with Ha added, total exposure time is 8 hours.
Messier 16, the “Eagle Nebula” a young open cluster of stars in constellation Serpens. Contained in this image is the “pillars of creation” made famous by Hubble Space Telescope. The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula is approximately 9.5 light-years or about 90 trillion kilometers long. Image shown here in SHO. 9 hours of exposure time on a 8 inch RC telescope.
Messier 95 in LRGB 4.5 hours of exposure. A barred spiral galaxy, 38 million light years away in Leo constellation.
