Order Notes

This was captured on the first night of the 2011 Oregon Star Party and there was smoke in the air, especially to the west. So I chose a bright target to the east, even though I couldn’t fit it all in the frame. Andromeda is a spiral galaxy that is fairly similar to our own Milky Way galaxy and our closest neighboring galaxy of similar size. Of course, “neighboring” may seem like a strange word to use, since it is over 2 million light years away! That means that this is actually a photograph of what Andromeda looked like 2 million years ago.

Mount: CGEM
Camera: QSI 583 at –15C

About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
