Welcome to the fold, Hornet - wondered if you'd managed to get onto the deal...
Nice shots too - and as you say, they'll get better - I'm at that point myself, and it's a nice feeling.
Gives the lie to the idea that you
must have an 80+mm scope to digiscope well, doesn't it?
As to the case: the Skua case is very nice, but £89's a bit steep: get in touch with Focal Point, and you'll get it for £60.
Like I did..!
