24"-36" Observatory
      #5610799 - 01/07/13 07:42 PM

Hi,

I was wondering if anybody knew where I could find a 24-36 inch dome observatory. I searched, but the smallest I could find was a 6 foot. I need the dome to have just enough space for my CGEM 800 to slew. I was thinking that I might have to build it from scratch.

Thanks,

ahan.tm

Indeed; Welcome to Cloudy Nights! That seems pretty small; is there a reason you cannot use a larger dome? 24"-36" definitely would not allow you to be in the dome with your setup; so I'm assuming it would be remote?

Are you reading the thread (current - look on index)

Pico Dome (it's that small)

Check this one out. Kevin gets amazing astrophotos with this set up.

Technical Inovations has a 42" model for robotic applications called the "RoboDome":

RoboDome

It's a complete turnkey robotic observatory.

Hi,

Thanks for your responses. Is the Robodome available dome and shutter only? How about the Motel o'Scope? It seems quite expensive for just basic parts($799). Any Motel o'Scope alternatives?

Thanks,

Just looked at the Motel oScope, for that much money I'd expect it to arrive assembled. Lot of cash for a few extruded & machined parts and a handful of fasteners. Especially since I think all of it is made up of bits from their other product lines repurposed and cut to size for this application. Seems pretty easy to reverse engineer this one for a lot less! I will happily pay top dollar for a great product/kit but this is not even a complete kit. JMHO and nothing more, no assembly required!

Here is a similar observatory built by a friend here in Maine.

24-36" dome does seem pretty small for an 8" sct on a GEM to slew...

You might look at other sources for spheres in that size that you could convert into a dome. Maybe like cisterns or if you're handy with fiberglass you could even make a dome using a large beach ball as a form.

In that size range I'm sure you can find some unsuspecting sphere to turn into a dome.

Now ... that's a very interesting idea! "EZ Tops" manufactures acrylic domes ... including a flange lip around the perimeter ... in 8" to 69" diameters, at very reasonable prices. A 42" dome is $193.35 ($224.65 for 1/4") ... add 10% for white. They do custom work ... so, I wonder if they have the capability to cut out a slot:

Heck, just get a clear one and shoot through it.

At that size, it would seem like maybe time to try building a weatherproof housing onto the mount. There actually are some devices like that out there- though they are custom build to the mount and telescope combination.

This is a little larger than 36" but it does
have possibilities and is inexpensive ($282.00).

Déjà vu?
That Poly company should do something with that cow dome of theirs... I have an Idea!

Trouble is their idea went from $282.00 to $1852.00.
I realize the Explora Dome is some what better but for
those looking for an inexpensive alternative. Gee I wonder
if the cow comes with it?

I have to say I agree. As a matter of fact, I got back into astronomy after reading about the NEW exploradome a few years back. The low price had me super interested in getting a new scope along with a dome observatory. Some time after buying the scope, and preparing for a OB build, the dome price doubled.

Oh Well. I'll have to live with the ROR....
