Very nice, Jen. Looks like a ripper and you have put a lot of thought into it. I hope it gives you many great years of service.
Curious, why the secrecy re the automated roof with the council?

Hopefully my obs will be ready way before September 😱 Do you still have your beautiful SDM I fell in love with that scope 😍😍
Great re your obs - I'll watch your progress reports.

Snake Valley in November - thinking seriously about it - probably at short notice if everything falls into place in time. I might have only binoculars to bring - everything else will be packed in boxes waiting for our new house to come into existence.

Yep, baby SDM#039 has been living in the northern hemisphere for five years, occasionally getting out at night and is dying to be under glorious southern skies again!

What are the dimensions of the pipe (wall thickness and diameter)? I am still trying to decide on steel or concrete pier. My scope is much bigger- 10 inch Schmidt Newtonian so the pier steel will need to be bigger.

That's looking fantastic. I'm envious, firstly you have a dark sky (presumably) and second with an observatory that size you can walk around without bashing your head on the mount or the scope. One day my family will find me unconscious in my 2.3m observatory felled by a bash to the head of the counterweight shaft!

Hi Jen,
My ob is 9x6 and appears to have a very similar structural design as yours.
What I did was installed some 'dropped' rafters (meaning the rolling roof goes over the top of them) between the two rails the roof slides on to when opened and then roofed them in tinted laserlight (lightweight compared to tin). I also put in an extra post either side to deal with the additional weight and put a color matched colorbond fence along one side to reduce wind/weather ingress.
This effectively gave me a dry area which I store lawnmowers and other bits and bobs in......seemed such a waste to have those 2 x rails sitting there holding up nothing most of the time.

The rails are engineered to hold the weight of the rolling roof and you would never have the roof open in heavy wind anyway so structurally it is fine.

It survived a 100km wind storm that tore down a heap of trees around my property last year so I'm guessing my calculations/assumptions on strength are right.
