That sounds reasonable
I depends on how far the walls are from the pier/scope, of course. That rotating roof design needs a fairly tall and narrow obsy ie. the side wall where the roof rotates down to has to be as high as the width of the roof. OTOH a wide/low obsy helps viewing at a lower angle. That is why I'm looking at a split apex roof with each half rotating down to the side. It's also easier to build. That curved roof looks like it's made of fibreglass. I guess you could use a wood paneled roof covered in felt. Then again I'd like the obsy to look as ordinary as possible - like a garden shed or (in my case) an animal shelter.

Exactly the dilemma I've got!
I think I'm beginning to home in on a design for my shed. But the wall height and scope height are still straining my brain!
I'd like my pier lower but for headroom I don't want the walls too low but low enough to be able to aim the scope close to the horizon.
The design I like best is "Harry's Astro Shed" http://www.harrysastroshed.com/shed.html
I'm thinking of basing my design on that.

Now that's what I'd call "good foundations"!

Yes, I'm doing it the other way round - decided how high I want the mount, building the pier to suit then building the walls to match that. Steel piers are too expensive. The scope height and position are paramount IMO.

That makes quick and easy work of it
Took me a week to dig a hole for the pier
Nice to see progress though
Well done

That's good Malcolm

I thought you'd worked it all out
Yes, it's certainly frustrating - I agree!! And yes, you need to be careful with your back. So easy to forget and overdo things. Good luck

Everything seems to take such a long time, doesn't it? But having a small digger available will make light work of digging out the plot and particularly the hole for the pier foundations. It's taken me about a week and a lot of hard work to dig my pier hole! But it's done now and I'm sorting out reinforcement. Trouble is, there's other jobs that have to take priority.
I see you have a tree right behind your plot - I hope that doesn't hinder your view too much. My first thought was that you already had a good base in that patio but I presume other factors came into it.

Very pleased too
Ordered EQ6 Pro SynScan mount late one afternoon and it arrived early next morning - can't beat that!

I've saved it to read later - should be good. Thank you
My education was in science and engineering so had a basis from any early age. My grandfather was interested in astronomy and I learnt quite a lot from him. Also read a number of books and been an avid watcher of "The Sky At Night" with Sir Patrick Moore.

I'm thinking of adding motor drive for focussing, particularly later on when I get a better scope for imaging. I've made a motor drive for my current mount - EQ2. I have experience in interfacing to computers so I could add computer control.

I've bought lots of stuff from ScrewFix, mainly for the house but other things too. It's amazing what you can get from them. Quick delivery too.
We have a couple tractor and farm suppliers in the nearest town and they supply nuts, bolts, washers etc. in single quantities. Mainly galvanised steel. I'm thinking of getting some studding for my pier from them, though admitted SS would be better.

Very interesting
I have captured a wide view of the stars with a Sony A200 DSLR and 18mm on the kit lens. Focussing wasn't a problem. I tried a series of photos at various exposures to see the effect. 30 secs was the best unless you want star traces, as has been said.
Years ago I used a Pentax Spotmatic film SLR and have several lenses from these days. I bought an M42 to A mount adapter to use the Pentax lenses with my Sony A200. Of course, the DSLR has to be on full Manual mode but these lenses are high quality and quite useful. Focal length is effectively increased by 1.5 times as the DSLR has a smaller frame area than 35mm film.

Good food for thought there - thank you
I have yet to try DSO imaging - now it doesn't seem as daunting as I thought
Thanks again

I did wonder what the ranks were. Thank you for the explanation
Dunno about a vacuum, probably more likely to be called a "gas bag"
My knowledge of astronomy is beginning to get a bit beyond a vacuum now but I think "vacuum" is quite apt for a beginner, and I don't care what I'm called - lived far too long to worry about that
OTOH I guess more experienced new members could feel a bit miffed. But if you're a new member of a forum you have to expect that. I think so anyway.
Shouldn't be tooooo long before my knowledge and contribution becomes a little more "nebulus"
Long live SGL
Love Gina.
Show me your eyepiece/accessories case, please.

I'm concentrating on getting things ready - I have a lot to do. I could use a tripod but need my sleep and all the setting up and taking down again is a bit of a pain. Even the sun isn't reliable ATM for white solar work. I also have a lot of work to do on the property so am tired at night and busy by day. This is a coffee break![:)](https://stargazerslounge.com/uploads//emoticons/default_smile.gif)
