My widefield Horsehead, Flame, Running Man and Orion Nebulae

I tried something new that I have not done before and that was to piggy back my 200mm lens with the Canon 60Da camera onto the 14".  I had planned on guiding but the coldness of mid 20*F kept me from that extra bit of setup.  I found that the 200mm at f/4 and 1600ISO on the 60Da did pretty well up to 2min unguided and even roughly aligned.

Here's a 1900x1200 HD version that will fit your screen pretty well http://i.imgur.com/4hYb6LM.png




Here's the monster full res version of 5200x3400, from the camera's resolution!  http://i.imgur.com/OUeiMQU.jpg


Next time I will try guiding but I think there might be a portion of my finder in the lower areas of the frame that is reflecting some light into the lens.  I'd like to look at resurrecting my old 6" with 4" guide scope onto a new mount for these types of shots as it is VERY fun and rewarding to use a one-shot color camera on nebula.  Nextime I will work harder to mask the brighter areas of the Orion Nebula too, as it's a bit washed out in some areas.

Thanks for looking,

Mike
