Description

After humming and hawing for years, I finally pulled the trigger on a 35mm lens for my old astro modified Canon 600D. I wanted something portable for 'grab and go' widefield full constellation and MW shots. My 600D has barely been used in the past 5 years since I moved over to mono CCD imaging, in fact I sold the camera a few years ago, then bought it back a year later and still have not been using it. The lens I purchased was 2nd hand off mpb.com, and is the EF F2 35mm IS USM. It arrived in excellent condition as advertised.

I've had a few nights playing with the combo and last night I had a somewhat interrupted session shooting Orion with my Canon 600D+35mm lens on the SA mount last night. I didn't get as much data as I'd like as I was dodging clouds and snow flurries yesterday evening - somewhat unsuccessfully....!! I set the camera running under a clear sky and came indoors to keep warm. When I went back out 20 mins later everything was covered in snow, so I had to start over, but even then I was only getting 10m-15m sessions between clouds and Orion started to set into trees, so I had to give up. Anyway, this is what I've managed to extract from the ~40 mins, or so of data that I did manage to collect. Orion was getting so low into the horizon LP and tree tops by the time I finished collecting data, that I've had to crop the lower edge pretty heavily, but I can just detect a hint of the Witch Head Nebula above the LP in the lower right corner. I really need a much longer session with Orion higher up to be able to push the stretch harder, but I feel as if I'm gradually getting there....
