My latest shot of M51 on the left is 14 x 600 second subs at 800 ISO.
My plan is to use the Canon 5D Mark II mainly on my TMB 130 but I thought it would be interesting to compare with the XSi image I took a few nights earlier.
This seems to confirm what I had already believed that I dont see much advantage in using the full size chip Canon 5D Mark II over the APS sized chip of the Canon XSi on the ATRC8.
Again this image is very noisy, only 5 darks were used.
Comments welcome of course.
