I have had this adaptor for the QHY to Canon EF mount for a fair while now, and only now got around to putting it all together (Thanks Ross G for the encouragement

)
I attempted this with my 350D last year and there's a huge difference with the CCD.
I used my 100mm macro lens for this one. I cropped most of the coma out from the corners, but I'm pretty happy with it
Almost 2 hours of 8 minute subs. on the HEQ5. I had to scrap 3 or so subs because of wind.
Feedback welcomed

thanks for looking.
Erik
