The
"RobServatory"
My "RobServatory" (OK it is a silly name but my
wife and kids get a kick out of it!) saw first light
on 12/22/05. I connected my SBig ST7XME CCD camera
but I did not do any imaging that night as the seeing
was bad and I was more concerned with getting
everything setup and verifying the "system" was
usable. I polar aligned the scope and made sure
everything was working. I did spend a little time at
the scope and I was able to catch a visual glimpse of
a few DSOs. Even with the quick polar alignment the
gotos were very close to dead on.
I have been wanting a permanent pier and
observatory for some time but have not had the money
to buy a prefabricated observatory and no time to
build one myself from scratch. Between bad weather,
working too much, and having to move and setup my
scope each time I wanted to star gaze or image, I had
not spent a night pursuing my hobby for several
months. with an observatory and permanent setup I am
hoping to alleviate at least one of those
excuses.
One day while at our local Sam's Club, I saw a
backyard utility shed that looked interesting. The
shed I looked at and eventually bought is called the
"Smart Shed Deluxe" made by "Thinking Outside". It is 11' L x 7' W
x 6' 7" H and costs ~$800. It is very simple in its
design and it seemed that with a little tweaking I
could make it into a decent observatory.
The shed has temporarily been erected on my back
porch. I originally meant to take photos of the shed
being assembled but with my Dad's help, it went up so
fast and easy that it was done in about 2.5 hours and
I didn't remember to grab the camera until it was
completed. My long term goal is to get a permanent
pier and a concrete slab put in on the south side of
my porch. Then I will move the shed to the new slab
and pier. Until that can be done, the scope is
sitting on its tripod inside the shed. The floor is
fairly heavy duty but does not sit completely flush
in all places with the underlying porch. I have
placed several CBS blocks under the tripod to help
prevent flexing of the shed floor. Not an ideal
imaging setup but again this is temporary.
There are two separate main roof panels and the
walls are 6' 7" high and there are no gabled ends to
get in the way. Once the roof panel is removed from
the East end of the shed (portion furthest from the
house) I am left with a covered area for me, my
laptop, and other equipment. The "Bay Window" faces
the window of my office and I can sit inside the
house at my desk and look into the shed. I will be
able to use Windows Remote Desktop function to
control the laptop from inside the house (think warm
in the winter and no mosquitoes in the summer). I can
also remote control the light in the shed using X10
technology and have a "kill" switch on the scope if
things go awry. I like to turn on the light and be
able to see the scope while it is slewing just in
case cables get tangled or the scope decides whatever
I am slewing to is below the horizon. The scope sits
at the western end of the shed and has as clear a
view of the sky as is possible from my backyard. The
limiting factor being the trees and houses not the
shed walls.
Removing one roof panel is relatively easy, I
loosen 6 screws from the lower truss support and then
remove 6 plastic bolts from around the perimeter of
the roof panel. I push up on the panel then back to
release it from the grooves it sits in, then I lay
the edge up on the remaining section of roof and
slide the panel back over it's mate. The panel slides
back rather easily but I have to be careful not to
damage the skylights. Once slid back, the panel
appears heavy enough to stay in place unless the wind
gusts pretty strong. I plan on trying to add some
sort of guides and a tie-down so I do not damage the
roof panels or skylights. I am thinking some PVC
pipes affixed to the top of the western roof section
may be what is needed as guides. I'll need to look
into it... (Note the images below all show both roof
sections in place.)
After removing the roof panel the only thing
holding up the eastern corners of the shed are the
doors. This left the doors and corners very wobbly
and subject to collapse and damage. I screwed a 1" x
4" board from the South side center brace to the
South East corner to add a bit of rigidity to the
structure. This also gave me a good way to route my
AC cord to the scope and the cables from the scope
and camera to the small work area counter under the
bay window where the laptop will sit.
There are only a few negatives that I have found
with this shed. The biggest problem is that it would
not take much to break into it. While I am OK with
leaving the scope in the shed while we are home, I am
keeping the eyepieces, CCD, laptop and other
expensive and easily stolen items in the house when
not in use. I figure anyone breaking into the shed
would have a heck of a time stealing the scope itself
without disassembling it. When we go away on vacation
I will take the scope in the house to secure it. The
other issue seems to be a small amount of water
intrusion around the doors when it rains really hard.
Right after we setup the shed we had a couple of days
of heavy rain and I noted some water leaking down the
center supports near the doors. I am going to look
into adding some seals around the doors to help make
them a bit more water and bug tight. When not in use
the scope and all electronics will remain covered to
keep out any water or dust.
So far I am very pleased with this shed. Although
not originally designed to be an observatory I think
it will work out well with a bit of tweaking. And for
the price I think it is a real bargain as far as
"observatories" go. Besides, if I ever get a "real"
observatory I can always relegate this shed to
housing my lawn tractor and yard tools.
