Well,As I’m the subject of this discussion I might as well comment!David, Dale and Callum have already covered much of thesubject already though. My 14" Cass/Newt f/20, f/5 was madeby the Hysom brothers in 1980 (I was 22). In those days itwas really a choice between Fullerscopes and AE. I’d prettymuch decided on AE due to their beefy mounts. In 1980 I wroteto Fullerscopes and AE about a custom 14". Fullerscopes neverreplied(!) but I got an instant reply from Rob Hysom of AE…It cost £4,115.85 in 1980…..a LOT of money.I used the 14" from 1980 to 2003 and gave it away to Mark Stuckey last year (2009)….he is the Norfolk AE collector.In 1991 Jim and Rob Hysom were separate entities but theyagreed to make me a 19.3" f/4.5 Newt for my Chelmsford house where I lived in the working week. I used that telescope from 1992 to 2002 and gave that away in 2008 to Glyn Marshwho lives on the Isle of Man. That behemoth cost about £10K!Jim Hysom knew Horace Dall well and AE was, in many ways,inspired by Dall. I went to my first BAA Winchester Weekendin 1975 and there used to be a 10" AE in a dome there atthe old King Alfred’s College. I remember as a 17 year oldqueueing for ages to look through it at Saturn. My AE telescopes were indestructible and the 14" lasted 23 yearsof regular use without a single problem. By comparison, a12" Meade LX200 I bought in 1997 lasted one night before acatastrophic failure!!! I think the last big telescope thatthe Hysom brothers made was Richard McKim’s 16" Cass whichhe still uses….that was around 1995 or so I think?The only reason I gave away the AE telescopes was thatthey were brutes to move around the sky and user unfriendly.But in terms of reliability and solid performance theywere excellent. The 18" wormwheel on the 19.3" Newt trackedas well as my Paramount ME, but there was no GO TO of course!BTW, Mobberley is spelt ‘ley’ at the end! ;-)Hope this is of interest…..Martin
