Hi all
I was using my gso superview 50mm in my homemade 14.5in f5.7 dob(vagely collimated as it is a work in progress)....what a fantastic eyepiece

. I had previously tried to use it in my 8in collapsible dob and had nothing but trouble

(lots of jelly-bean effect). Sure am glad I didn't sell it and I might even get some more of them...

a very happy Phill
