Shed for 25"

 

I live near DC and have owned an18UC for 11 years, happily commuting to dark sky sites 50 miles west of town to do my observing. ?I've had great success with the 18UC but am now looking for a property west of town and when I find it, I'm also considering getting a 25" Classic. ?Depending on the property, I might be able to keep the 25" in a garage or shed, and roll it out for use. ?But if not, I may need to set up some kind of observatory or roll away shed to house the 25". ?I'd like to keep it as simple and as small as possible. ?I don't want to undertake a major construction project. ?I just want to be able to use the scope with minimal fuss. ?I intend to use it visually - no astrophotography. ?I'm aware that there are some commercial off the shelf products out there, but am guessing that most of them are too small for a 25"?

I'd appreciate hearing about what others have done.

Sincerely,
Bob Gardner
 

Hi Bob,

I too live in the DC area but decided to build a "shed" for my Classic 18" for visual observing in my moderately polluted backyard. A roll off seemed unnecessarily complicated so basically I built a 6x8 footprint wooden shed but with a much taller and wider door and steeper roof. I roll the assembled telescope in and out of the building. Voila! In a few minutes I can be up and observing. An assembled ?25" is going to be almost 2 feet taller than an 18" which a modified shed could accommodate.?

I also made a conscious choice to build the shed on top of a small wooden deck so that in snowy winter conditions I can roll the telescope out of the shed and observe from the cleared off deck. I don't have a special area of the deck to "isolate" the telescope but I did reinforce that part of the deck and find that if it is just me observing there is very little vibration transmitted from the deck to the telescope. A set of ramps that I use to wheel the disassembled telescope in and out of the back of my SUV also serve the dual purpose of providing a gentle slope to roll the telescope off the deck and onto the grass of the back yard. Two short bungy cords from the mirror box to the wheelbarrow handles mitigate any propensity of the OTA from "jumping" out of the mirror box (which has never happened to me but I have heard horror stories).

Good luck and clear skies!

Regards,
Rich

Hi Bob,

?

I live in rural Kansas, under moderately dark skies.? I had contemplating building a ¡°Dobservatory¡±? with 4 foot side walls, and a roll off roof.? The cost would be in the 15k to 20K range.?

?

I have since decided on a roll off shed.? In that the telescope remains in place and the shed rolls off on tracks.? This can be built for a fraction of the cost.? There are a few photos on the internet of this type of observatory.? The advantage being that the telescope does not have to be moved.

?

Regards,

Rich,

Thanks for the response. ?I like your idea a lot. ?I had a shed built in my backyard a couple of years ago to house yard equipment. ?This was done for a very reasonable price. ?I think I could have asked the person who built it for me tailor the design to allow for storing and rolling out a 25". ?The only thing I might do different would be to pour a concrete pad in front of the shed to roll the scope onto for observing. ?

Thanks again,
Bob
 

Jim,

Thanks for the feedback. ?That is a great idea. ?It might be necessary if I can't easily move the 25" using the wheelbarrel handles. ?I'll have to weigh that possibility carefully!

Thanks,

Bob
