Yeah now that I think about it my dSLR images are sharper. Hmmm I didn't expect it as each individual frame is far more noisy than the DMK. The dSLR wins at frame rate though being 25fps compared to the 15fps that the DMK41 can record.
I try not to record over a minute but even so you can see that that extra 10fps adds up fast. Not quite double but nearly.
The problem with my dSLR is that it only records .mov format. In the past I would convert the .mov to image sequence then load that into registax and stack it that way. However now I convert it to avi then I often have to fix it in virtual dub. Then I can stack it. Works an absolute treat now.
I think the main difference between my dSLR and DMK shots is the magnification. As one would expect the higher you go the more problems you will run into. I use the same Barlow/s on my dSLR as the DMK. However the DMK has a much smaller chip size and as such magnifies everything much more. It is fine at prime focus however with the barlow/s it gets to be to high a magnification under anything but pristine seeing conditions.
So if anything all this trial and error has helped me get to know my gear and limitations.
I do have another problem now though. It is becoming addictive.
