Markarian's Chain

I captured this image over two nights and made a rookie mistake the first night, orienting the camera 90 degrees to what I wanted. I corrected this the second night but then of course the images only partially overlapped: the left 25% of this image is therefore 13x900s, and the remainder 25x900. There is some unfortunate stretching of stars, all from the second night, which I'm pretty sure came from slight creeping of the meltwater-saturated ground under my setup.

south of Foymount, Ontario; March 26 and March 29, 2011; Orion Pro on TV-85 at f5.6; Hutech LPS filter; seeing fair (very windy first night) to excellent; autoguided; 25x900 seconds.
