All,
Not exactly the best image to call a swan song for my current setup (the ED127 is gone, as is my William Optics ZenithStar, and the modified Canon EOS 40D), however, I did use my 5D Mark II for this at ISO-1600. Each sub-exposure is void of noise. I love this camera.
This is the only useable data from three night's of imaging at Frank Bonneville's place up at Manar (thanks Frank!). The other two night's worth, including 5+ hours on Rho Ophiuchus through a 200mm lens was a disaster as Frank's 20Da was flexing on my ADM Manfrotto ballhead mount. I thought I'd tightened it up pretty good, but, obviously not.
This is a crop from towards the middle of the frame, as the ED127's focuser is, in no uncertain terms, useless when it comes to illuminating a full-frame 35mm sensor. Also, as the camera is quite heavy, it wasn't sitting square and there's a bit of elongation happening.
Anyway, enough excuses -- it was my final image with my current setup until the new gear arrives, and I thought I'd share.
