如果你是訂做的話,價錢有點過份便宜,玻璃纖維實際價錢比鋼材還要貴。
補充:如果祇是用玻璃纖維做小圓頂,那麼¥2,800也算合理。

This appears to be a very small dome with very low profile. Are you sure you can easily maneuver inside with your equipment? Your scope probably is quite small as well. It will also limit your mount to be a fork or alt-azi type. I think it will be difficult to fit a german mount inside. Just some off-the-cuff feelings... :roll:

Only the Dome is made by 波离钢 .
The diameter of dome is 1M , height is around 0.5M .
2000 RMB not include the transportation charges .


The circular room or wall is 2M in diameter . Height is 1.13M .
And the Dome is put over the room .

During my design stage , I have considered very seriously the size of the whole 天文台 . Such size is enough for all kinds of usage . And also most safety for long term usage . You know too high building is no good ( danger ) and too large(e.g 2M) of the Dome is also no good . Total height of the building is around 1.75M . Altough standing inside is not really comfortable but normally sitting inside during night observation or daytime working inside is pretty enough . Laying down inside for sleeping is also considered of 2M diameter . The room is enough to be occupied around 3 to 4 persons sitting inside at same time .

Finally , the most important part for this room is that it is highly heat insulated by using a very special heat resistant coating( 600RMB) .This coating is an adanced technology so far in china which can reduce inside temperature to around 20 degree less than outside surface . Thus , working or doing things in day time is possible during summer time .

去年在台灣都見過一個小型的dome, 大小剛好跟MANDII 的差不多。

The mount can be shortened on the leg . Plus the telescope I think should not be over 1.75 M . And also , pls don't forget I just sitting inside . There is still have 2M diameter room . Although I haven't had a german moult so far , I even do not have a telescope . I just have my binocula(10X50) which is put over my observating table , And the table in future can be put inside the new room . Of course , this is a life lasting hobby , in future I will definitely buy those equipments . I had checked the german moult size (e.g Meade ED75 ) , I think it should be enough for me for such room size .

台灣個DOME應該無兩米直徑吧?
價錢又要幾多呢?
