    Thumbs up



    Mandii, I am blown away! Look what you did while I was away! GOOD JOB, MY FRIEND !!!!

    The final result is very nice looking! I applaud you and your efforts !

    A few questions, if you don't mind:
    + What is the material of which the dome is made?
    + Was the dome made specifically for your project, or adapted from some other application?
    + What are your finished dimensions inside your ob, i.e., diameter of the dome, inside wall dimensions?

    I am so very impressed. You make me feel like an old turtle, when I compare my rate of progress to your's...!

    Dear Bob ,

    Your one is a big project indeed and takes time is reasonable !
    My one is just a small toy only .
    All the components( Dome , door and track) are designed by me and I ask other to specificly make it for me . Only the wall is made by me and my uncle .


    The Dome is made by FRP(fiberglass reinforced plastic) .

    The finished dimentions counted from internally not externally is listed below :

    DOME is around 1 M in diameter and 50cm height .
    The wall dimentions are 2M diameter and 113cm height .
    The Iron track is 10cm height and around 1 M in diameter .

    Thus , total height count from the ground to the top of the Dome is 113+10+50 = 173 cm . which is a little bit higher than my body height . But oftenly , I sit down on a small chair for observation . And there is still have 10 cm space to touch my head to the ceilling .

    Hello MANDII, Thank you for the additional information. You have done a fine job with this!

    The dome you used fascinates me. Does you supplier have large domes available? I have the feeling there is a commercial opportunity for larger domes. Perhaps, you would do well to follow up on this?

    In any case, job well done!

    Dan at Explora-dome is working on a 11' or 11'6" slotted dome right now and is putting out feelers ...

    The original Exploradome was an 8' dome ...one piece
    and transporting it was the main reason for limiting it to 8
    foot...

    The 11 footer will not be one piece...it will be in 3 sections just so it can be shipped at a reasonable price via a regular tractor trailer...

    I'm perfectly happy with my 8' Exploradome (seen in my avatar) plenty of storage room in the 10x10 building. it has been completely leak free and problem free for over 3 years now so I have nothing to complain about

    BUT Today I would have gone with the11 footer and put it on a 14 or 16 foot square building... Seems that if you have the space "something" ends up being stored in that space...

    basicly, they can make any size and any shape once you give them the specification drawing( like those I provided in this thread previously ) . they make it according your drawings only . A larger Dome will be much higher in price . My Dome is 1M diamter , it cost 2000HKD . Last time I ask for 1.5M , but it takes nearly 5000HKD . Not including the shipping charges

    Actually , the size of Dome depends one's usage of the telescope .
    In my case , I am not planning to have a very big telescope and mount indeed . Thus, at the beginning I had consider very seriously this 1M size . And I think that's enough of my observation and photography usage now and in future for at least ten to twenty years of time ,Ha ha . And also , in my understanding , the Dome can be smaller ( once it has enough space for the scopes and mounts to be manupulated freely ) but the room should be large enough to occupy at least two persons . And it's better to use the room space below the dome space to use the telescope , I mean the eyepiece of the telescope should be in lower position better such that you can sit on a small chair comfortably to look into the eyepiece and your head will no need to go into the space of the dome . A long refractive scope is sutable in this case , or a folk mount scope

    I agree ... The size of the Dome only needs to be big enough to allow the scope itself to function without any obstruction... The building however needs to be big enough to house your equipment and you.

    It looks like you have both...

    My building is only 10x10 feet (hair over 3 meters square, the dome is 8 foot in diameter ..about 2.4 meters... I can fit 4 observers inside BUT we have to play games and move around to let everyone get to the eyepiece...BUT I observe 95 percent of the time alone. My walls are only 3 foot tall...and the bottom of my shutter is 4 foot off the floor of the observatory..which allows me to sit comfortably at the scope and are just tall enough that I can use my computer at the desk without banging my head...

    I elivated my obs to get a view above some trees so I enter thru a trap door in the floor by climbing up a ladder so without the need for a door in the wall I did not need a wall tall enough for a door to fit on...

    Only drawback I ever had was when I broke my leg...(hard to climb a ladder in the dark with your leg in a cast.. actually not hard to climb up but climbing down is an adventure ...not fun) ...

    I solved that problem by installing an electric hoist inside the observatory and made my own elevator ... worked like a charm so I still use it today...

    I'm not exactly happy with my computer (laptop) in the Observatory however... I'm thinking of taking it back into the house after each use ... If I go 4-5 days without using the observatory because of clouds etc It takes 10-15 minutes for the computer to fully load because it is busy updating itself running virus checks etc... this frustrates me...!!!

    Clear skies Young man...enjoy your observatory...you put a lot of though and work into it...now its time to enjoy the fruits of you labor...
