Very interesting comparison here, showing the image scale obtained in my old imaging rig (with Jupiter last year) versus the new.
It's not really a true comparison of image scale of the 10" versus the 12", because in the image with the 10", I was using the ToUcam - whereas with the 12", I'm using the DMK - which has the added extension of the filter wheel, making the 5x powermate act like a 6x or 6.5x.
So while it's not a 10" v 12" comparison, it's still showing the image scale I got with Jupiter last year, compared to the same stage in the apparition this year (35.1" diameter).
Quite a big increase in scale, and i'm looking forward to when Jupiter is over 45"!
I'll do a similar comparison with Saturn in the next few days, where both were taken with the DMK + 5x powermate - so only the scope has changed.
