Michael, Thanks!!

I used the "Canopus 320" which I built in the late 70's for visual SN work. I checked hundreds of charts for Gregg Thompson and the "Supernova Search Charts"

I could get 15.5 mag limit from 15Km north of the city of Melbourne Australia.

Haaaa those were the days!!

I think what used to be achieved remarkable and the dedication involved staggering. Giants are standing on my shoulders. ;-)

Or in my case you employ a Carpenter as i have neither the skills or the physical ability (back bolted) since my operation.

I'm sure it was an interesting and unusual project for him. It would be interesting to know in approximate terms how much the cost of doing it this way compares with buying a ready made observatory.

A lot more expensive. Its the shape that created a lot of waste. However that is what it took for it to be approved I could have bought a Pulsar 2.2 metre dome and put cladding around the base cheaper. About £4k in total.

Ooooh!  I vaguely thought it might come out about half as much as for a Pulsar observatory alone. Mind you, the total cost of a Pulsar 2.2m observatory, with pier, drives, installation etc, is in the region of £6k.  That's not including the base.

Mine has no drives. Purely 1 Michael power to turn it. Gas struts from a Zafira lift the lid.
