New Obsy in the making

Recommended Posts

Moved house and after a long pause, I started a new build as the one I had in the old place (https://stargazerslounge.com/topic/285320-first-obsy-build/) would never stand the conditions of where we moved. It's quite windy.

So, here is the status of the new one. I've had lots of help and hopefully on the 17th October, everything will start to come in place.

First the base. I got permission to sacrifice a plant box on a corner of the garden that faces south-west. There are no neighbors and so I have a light-less and unrestricted view from South to South-West and about 60 degrees to the north. The base was laid a couple of weeks ago with a long run of armoured cable going from the house to the end of the garden (about 30 meters).

The obsy is being built and tested in a warehouse. It's a proper ROR this time and emphasis has been placed on making things water tights and solid because of the wind. 

The next few picture show the state of affairs at the beginning of Sept.

View from the inside. More rollers are coming and hopefully moving the roof is going to be like spreading butter...

Work in progress...

Very nice! :)

I sleep and dream of something similar! :)

P.S.

You forgot the pilar...

Will you bolt it in?

Hi,

I'm not sure about the pilar as the ground was not cooperating for this. So, I decided for a double floor. The wooden floor with holes for the tripod legs, which will rest on the concrete pad. Walking on the wooden floor should not transmit any vibrations to the tripod. 

Indeed, the shed will be bolted into the concrete base.

Thanks for watching 🙂

The rollers and kept in-line by the roof itself running in parallel on the track bar you can see in in the second picture. We thought of using V-shaped rollers but these could not be procured. More rollers are being installed to make the effort required to move the roof as small as possible.

So, today, finally, the obsy arrived and we've assembled it.  Panels and bits coming off the lorry...20181016_105834.thumb.jpg.aac52f5f9121f4c4f0a946deea2588e1.jpg

 

The roof is coming...Quite a complex task due to the hedges around our house.

Roof in place. Some heavy duty adjustments required to get everything to line-up nicely....

Getting close to the end of the working day. Just need to make sure that everything is as it should and enough support is in place.

And there is lots more to show/discuss (not everything is perfect but as an amateur astronomer, I know that many things are a good compromise as long as they work.

Now I've got to do as promised to my other half...some real work!

Lots of work has been done. SW ED80MM is in. Electrics are sorted out. Roof is heavy but rolls free. I have sorted out a way to move it for £6.

Like it, anything to ease the work load is good in my book. I'd certainly look at incorporating a garage door motor to open and close the roof, in the future. But, first I would want to be in there observing and imaging. Have you had any time using the Obsy for imaging?

My observatory roof which runs on 4 large (120mm OD) wheels and round section track I can push ope closed with one finger.  And I reckon it's a lot heavier.

I've missed this thread up until now.  Looks like a very nice little build.

I have found that one of the great joys of having an observatory is that polar alignment is pretty much a one off affair.  Not having a pier will remove this advantage as the tripod is bound to occasionally get knocked.

Merry Christmas to all and thanks for the the views and feedback. I've managed to get the SWED80 going it's true i do have to be careful walking around the tripod legs. Do far I've been lucky and will post a lunar stack on the imaging forums and an unguided M42 that marks first light for the obsy on the 24 December! The biggest challenge has been processing the data from an ASI 1600 MC. Getting the right debayer pattern has taken up a lot of time.

Nice job but I agree with others here. Lose the tripod and the block and tackle.

Or, you'll spend the rest of your life untangling cord. Been there, done that, much too often.  :blush:
