Full frame image with 100px crop on the borders to remove the dithering artifacts.

Nice image Kev, I've got a WOZ61 that doesn't see much use must try to set it up on the Star Adventurer while the other rig is imaging.

Curious about the image scale 9.77, I use a Canon 60Da on mine which I think from memory gives around 2.5 as/pixel presumably the 5D has bigger pixels but your figure looks a bit high ?

I saw that as well Dave, CCDCalc reports the scale as 3.07arc-sec/pixel which I used for my dithering calculation (6720px wide sensor and 5.36 micron pixel size).

Okay I know why, I resized the full frame down to 2048 pixels wide for Nova to work on :) I've corrected the top post
