I presume you can build up a cache because obviously at Astrofest we have no Internet connection. I will plan a whole bunch of mosaics before then. I've had the tool since last year actually and just never got around to using it.
This year is different for me though because it is the first year I've had an observatory which means I've had lots of practice which is great. Normally, having not used the equipment since the last AF the first night is wasted trying to remember how to use all the software
. That puts mosaics firmly on the radar for this year and in general from the observatory moving forward.
I remain puzzled about how one stitches them together in the processing though, although I am guessing, as with so much else, the software just does it automatically
