玩得高興就好啦！
有時候設備是現實的
要玩出什麼效果看個人的想法
科學重在真實，藝術在某個層面也反映出內心的真實
但往往探索與追求這真實就耗掉某個程度的心力
求得的結果，可能自己都還懷疑他是不是真實
太去在意成果，往往是在追求那毫不可能或不太真實的百分之百
沮喪會再越接近的時候越大
但如果心態轉而去享受這中間的過程，那樂趣就大多了

不要把我一的一己之見看得太重，我直接反應我的看法，也不要想太多
你正在享受那個過程，那才是最有樂趣的地方，也很高興你可以分享給大家
最近我也在找新的點子來玩玩，但我玩到後來的成果都用不上
哈哈！也不知道在搞什麼

對不起！一些謬論影響了你一整天

[MANDII]

恩,个人而言，不论成果讲乐趣这是说得对。另大众游戏规则也是要的，也是存在的，我说过这游戏很公平公正。
只是我以前没有很好地理解到这个游戏规则,我在这个论坛唯一学到的,便是这一点，我觉得很有启发性。
不分成果，不分好瀤，只会计较成本，这并不是好事，个人可以做不到，但不能说这游戏不对。
做不到就小出声，严格来说做不到，就连发言权都不应该有的，这是基本的道德，做人的原则。
我目前是做不到了，也看不到前面会有很大的改变余地。

没有影响我心情的啦，大家想说便说而已。

[大瘋起嘻]

成本是一定會有的

當然這也是選擇性的問題

我個人也不會太去計算成本, 大致上我的設備都是中低階

但那也不會影響我玩天文的樂趣

因為我的樂趣並不是在用最好, 拍最好的, 而是在嘗試

所以我現在大部份都拿著攝星板來拍, 最近又想要改一些結構能夠自由追蹤

我喜歡想法跟別人不一樣, 哈哈! 一陣子一定讓大家嚇一跳

" 那棚架有轮子，可以很顺滑地转动竿，把帆布拉开和收起。
它的位置已予留和倆边成90度的墙壁隔开一尺半的宽度，以后会再弄花槽，种高高的树木，
像那颗松树那么高的密密的，那样就成了一个空中花园，也可以挡光。"


去年12月13日我在贴里是按上面那么说的，刚过去的星期天，终于把花槽差不多造好了。
我从6月开始拍板做，一做就做上了一个月半时间，期间我是大部份在晚上弄的，
这次整个工程真的只有我一个人做了，由头带到尾。
高技术高科技的东西我不会DIY，像这种粗东西我还是能应负得来。
玩天文，让我发挥了不少的创造能力，好像DIY有个瘾那样，一年一个工程项目，09年搞天文台，10年搞活动棚架和白房（白房就不算我搞 ，只是买），然后今年11年就搞了花槽。明年到时可能没啥东西搞就真的会去搞大牛反。
目前4大工程，总的来说，我觉得为何要DIY呢，就是要自己怎么想，就怎么去做，要实现心里所想的，然后要省钱，就是那样。



花槽长4米半和3米半倆段成L型铺于天台俩边,高42公分(厘米),阔40公分,决定自己动手做前找过几家装修公司了解情况,像这样尺寸的花槽价钱要1万 2左右,外层磁砖要是他们规定的那种一般国内磁砖,如果要好的磁砖就还得另外加钱。我自己在香港买日本进口的才1200港币,一共130多条倆种磁砖,加上内层红砖180多块,15包沙,2包英泥,,1瓶英泥宝加强密度和防水功效,还有4包石仔,一共1000左右,连磁砖总材料包运费在2300港币,就那么多了。 另外树木方面，装修公司以面积每平方尺计算，一平方400港币，包泥土，肥料和植物，植物也是他们规定好，也不怎么样那种，也可以补钱买好的。那按那样算我面积有(长:8米x3.3=26.4尺,阔:40厘米/33=1.2尺),那就31.6平方尺,即1万3千港币，而且还都是一些很小颗的植物。那如果找装修公司总价要2万5港币。
那些树木我便决定在深圳花草批发市场买，品种又多又平宜，我买了8棵罗汉松，每棵才120人民币，像那么高大的罗汉松每棵在香港要7，8百。8棵就 6000了。还有2棵紫微树，一棵芒果树（有长5个芒果），竹子18支，6盘抹梨花，还有藤类花几盘，其它的小花小草，一共就1800人民币。

另泥土最花钱，你看不出来要下那么多土的，我是问深圳买花那里才知道要下多少土的，1个立方米花槽就得1300公斤（KG）的土，即1.3吨土，我那里是 1.4立方米，就得买1800公斤左右的土，我买了1700公斤,90包总共。在香港同样的一包土要35块一包（20多公斤），那按正常光泥土都要 3100港币了,肥料3包每包80，240了。我在深圳买80包才500人民币,3包肥料150。加上运费1900人民币，运费指的是全部东西，树木连泥土一车过运来香港，送到家门口，一共是1900人民币。那么等于是我买花和土花了(1800+500+150+1900=4350)人民币,即5200港币花了。

对比一下真有意思，如果是正常在香港买花和土，就只说那8棵罗汉松和土吧，其它的植物都不计算,得要 6000+3100+240=9340港币，我现在才 5200港币，还多了10几盘植物出来。花槽我那里本来要1万三也只要2300,那整个花槽连花，本来总价一共是13000+9340=22340（只得 8颗罗汉松),我现在只要5200+2300=7800(包所有的树和花）, 我想其它的树和花那里在香港买起码也得要个3000的。那么，总造价2万6是跑不掉的，我现在只要7800，即8000总造价可以了,省了3份2成本,省了18000接近倆万港币。

US ASTRONOMY/CLOUDY NIGHTS

The Observatory is located on the platform . It's necessary to make the platform looks better . I had designed the whole platform indeed , since the day I built this Observatory 2 years ago . At that time I thought it should be looks like a garden , with a house . Last year the house is built , and I had made one sheld as well . The cover on the shelter can be opened and closed by rolling . The house is bought and not made by me . But the rolling shelter is made by me one person . This year , I decide to settle all the plants and build up an observatory garden . Those trees can sheld lots of light that come from western side of the platform . Height of the trees and house was designed not higher than 20 degree elevation when looking from the the observatory .

Samely , everything needed DIY , to save money . And turns impossible to possible .
I DIY a concret container for plants , total cost including all the palnts and soil is around 8000 HKD , saving at least 20 thousand HK dollars if I ask the shop to build one for me . I spent nearly 1 and half month to complete this build . Most of the time I make it at night time after daily work . It was nearly completed last sunday . Very tired indeed recently . but very happy .

Astronomy remind me one thing , Keep on doing things by own ,step by steply .

CLOUDY NIGHTS



MANDII : 07/15/11 04:45 AM
Yes Mike , quite lots of work indeed , but fortunately I just spent the time longer . bit by bit can finish tough works . You know the time is always the best helper .

I had to bring nearly 90 packages of soil , each package around 20 KG upstair 3 floors . You don't heard about that 1 cubic meter volunm of container needed to be filled nearly 1300KG of soil . I aslo do not know it before . And my container is about 1.3 cubic meter ( 8M * 0.42M* 0.4M=1.3 ) in volunm , so need totally 1700KG of soil .

I had calling local people to pick these bags actually , but they charged me too much . very expensive that they counted me in each KG and needed over 1500 dollars . Well , I forgot how much the exactly charges now , but anyway very expensive that I could not accept it at that time . Finally ... I pick up bag by bag , in nearly 1 week of nights .






MANDII : 07/19/11 11:05 PM

Once again thank you Sir Herman . I see you also have a big telescope and probably an observatory in your icon picture .

Well , you let me thinking once again the whole story now .. .
Actually , most importantly and main purpose in setting up these trees , is to work as a SUN shelter . In local HK climate , there is two months you are feeling hot in a whole year , July and August . The temperature can always reach to over 30 degree celcious . The other 10 months are not hot . In down floor living room you don't need to turn on the internal air conditioner in these months , except the two hotest months in Summer time . According my observation experience in these years , the rooftop platform is getting hot starting from noon time , and reach the higest temperature at 4 o'clock afternoon , And then it starts to drops down . Thus , the amount of the sun moving shadow that it lays and moves on the rooftop , that was shelted by the rolling cover(cloths) and the trees , should be counted the area according to the sun moving time starting noon time to 4'clock , and in which specific direction and location as well . As of now , totally 8 meters long Tree container shelding the West and South West Sun heat ,and about 1.9M height of these trees ,can covers over 70% areas on the rooftop . I mean the total covering area that takes effect when the shadow moves at these afetrnoon time range . The rolling shelter cloths can be opened and closed by a steel wheel , in nightime and daytime respectively . Most of the other months in a year , I open the shelter such that I still can look at the night sky .

How many , how big and which location I should setup these trees and the shelter , is needed to be decided . And needed to be designed at the beginning time . At the very beginning indeed counting to the time when deciding to build this obesrvatory two years ago indeed ! The difficulty is also at the very beginning time when it's hard to decide these kind of things . But you are not able to change everthing anymore , after it was built . Old chinese word always tells me the truth . " Things started not easily at the beginning time , and getting easy as you go stepping forward one by one " .

Thank you Sir .

The Hong Kong Observatory located at the highest mountain in Hong Kong , is very far away from my observatory and from my telescope . Should have more than 10 kilometers distance apart from here . But today I can peer it with my DSI ,through those leaves and trees nearby . I had recorded down it's visual coordinates as well .

这个可能是鸟巢。因为风比较大，树摇得很利害，便用web cam 好叠加一点。
This is the bird nest , since today is windy , the tree moves a lot , so I choose to use web cam for fast capture and more accurate stacking of images . I start to find it since noon time , outside temperature reach 32 degree celcious , but in the observatory it's quite cool when the dome and the door is opened .
