CaK Full Disk 19th July


A bit of playing around with yesterdays full disks in CaK, the disk at the top is my regular image - 40mm scope 650mm focal length, the image underneath with the Ed60 at 975mm focal length, a central swathe of the regions of interest.  I wondered which would work best; well, to my surprise the smaller scope showed the better clarity.  Maybe the seeing wasn't as good with the ED60?  I don't know, but for now I think i'll stick with the regular 40mm instrument.
