Sounds great
I think I remember hints from GSO about a 20" a couple of years back.
I wasn't aware Sky Watcher made mirrors. I thought they used Synta
mirrors. I'd be interested to know who is actually making the mirror...
hopefully GSO
. I brought my 16" primary direct from them last year
for AUD$782.00 where locally a well known retailer were trying to flog
the same thing for $1800.00. I'll buy the mirror direct if I can and build
the scope around it.
