Recently I have been conbritubting many hours of photography to the global effort of documenting and characterizing the comet C/2013 A1 (Siding Spring). This comet will be passing very close to Mars in October. Observations of this comet are useful to agencies such as NASA who have hardware orbiting Mars. Today I published a fun little video of images from just one night, the 24th August. You can see it at Vimeo below.
See this and more galaxies in my galaxy gallery. This is probably one of my better LRGB galaxies to date, not something I do very often (LRGB imaging). To view a plate-sovle of this image which shows the objects in it (when you hover your mouse over the image) see it on my astrobin account: http://www.astrobin.com/113009/. It will also show you where in the sky this galaxy is located.
There are some nice sunspots with extra surface detail surrounding, today. This photograph was taken using my Megrez 90 APO telescope, Canon 6D, Tamron 2x teleconverter, Kenko extension tubes (between 2x and 6D body). It’s a stack of 470 frames recorded using Backyard EOS. A Baader white light filter was used (never look at or photograph directly at he sun without a safe filter).
