View Full Version here: : Finally the observatory build has commenced!

After much procrastination, my home observatory is finally underway. My biggest difficulty was deciding on the location, as having a fairly small yard, there were limited options available.

I decided on the south-west corner of the yard, where I had a small 5’ by 6’ garden shed. The benefit of this spot was that,

i. It had the most sky visible out of the whole backyard
ii. I had pretty decent access to the northern sky, in comparison to where I normally set up in the middle of the yard, where the house blocks that part of the sky
iii. The existing brickwall feature will hide the observatory and not impede on the aesthetics of the yard

Because of the location I had selected, the “works” would need to be staged, as follows

1. Clear the apple, cherry and quince trees at the side of the house
2. Build a new garden shed at the side of the house
3. Dismantle existing shed and build the observatory in its place.

The design concept for the observatory that I had in mind was to eliminate the requirement for support posts and railing for the sliding roof. Instead, I decided on a sliding roof that will pivot and then hang at the end of the rail (with necessary safety precautions in place). I think I will be able to get away with this, as the roof area will be quite small (1500mm x 2000mm). I intend to frame the roof utilising either 70x35 timber, or if I can get it at a decent price, aluminium tubing.

As mentioned above, I really wanted to keep the existing brick wall intact, hence I had a very challenging envelope to work with. Basically, if I fitted the whole available area with the observatory, then I would have a slanted parallelogram floor plan, which would allow approximately 1600mm between the east and west walls. Later on, once the existing garden shed was removed, I did a trial set up within this area, which proved to be very tight but very do-able. I concluded that having a very small observatory was much better than not having one at all.

Due to the space constraints, I decided to pre-fabricate the east and west walls, then put them in place, and from there complete the rest of the structure.

At this stage, I will just have the EQ6 mounted on its tripod rather than going for a pier. Once I am happy with the position of everything, I may then consider a pier. I have completed a “jump test” whilst guiding with the DMK through the ED80, and no movement was noticeable on the graph.

One thing that I must add is that I am not a “handyman”. But, I am willing to give it a go, and basically, if I can do it, then anyone can!

So, at the end of the first few days, I am quite happy with the progress. I will now complete the door and then get a start on the roof. Cannot wait.

Thanks for looking.

Cheers,

Daniel

You've got the priorities right, but clearing out three great fruit tress!!!. Should've planned around them...think of the health benefits observing and eating fresh fruit at the same time. And they say staying up all night looking at pretty lights isn't good for you:):P

Fair point, but I think the apple tree was diseased, the cherries just would not do well in metropolitan Adelaide..........;), and I just need the obs!!

Good Luck Daniel.
The lemon tree survived in our back yard.
Those Christmas lights might have to go as well... perhaps you can surreptitiously remove one light bulb in the chain? :P

Getting pretty close now. In fact, did a trial run tonight!!:D

Basically the structure is in place now. Just need to do a bit of waterproofing (aka silicon) on some of the interfaces, and put some insulation into the roof and the front wall/door.

All in all I am quite happy with it (so far). It would have been much nicer if it was bigger, but by the same token, it is much better than having to setup from scratch every night.

Getting there.........

Cheers,

Daniel

I thought I had a SMALL backyard!
I have a courtyard about 3.5m w X 3.5m l and about 3m h.
Have to move the outdoor setting each time I want to set up the scope.

Well Done on the Construction.
Looks solid and workable!

Here a a few pics of my courtyard.....:D

Thanks Peter! I am sure I will be using the setup a lot more now.... I often found it "too hard" to be bothered in setting up and therefore missed a lot of opportunities:thumbsup:

Thanks for the comments Bart:thumbsup:

By the way, nice setup!! I have honestly been thinking of purchasing the BD 254 reflector to mount to the EQ6 for visual use. How do you find the eyepiece position at various points in the sky? I would imagine that it would get into some awkward positions.

Cheers,

Daniel
