親子觀星會

前幾次ISS經過都是移動望遠鏡追著它打~
結果ISS移動太快了~~好幾次都失敗

這次詳細確認它會經過的星圖位置
把赤道儀定在定點上等ISS經過
然後在那不確定它到底那幾秒會經過的一分鐘內卯起來按快門
因為它在530mm的視野裡只會經過4秒鐘左右
所以把ISO拉到1000增快快門好讓它定住不要拉出線
快門1/400秒~還是有點過曝了~下次試試再快一點的快門
530mm+40D拍出來未裁切就這麼一小點
應該也算失敗了~下次換800mm試試

老實說~拍這ISS實在對身體不好~
精神壓力太大了~等著那幾秒鐘不能出錯~對老人家來說心臟的負荷太大了~哈哈哈~

炫大要不要把尋星鏡換上內紅點尋星鏡試試看!
用紅點追著太空站來移動望遠鏡拍攝,應該不錯用.
我雖沒試過,但祝您成功! ;D

主要的困難是赤道儀
它的轉動方式跟ISS走的軌道不同
要移動赤道儀上的望遠鏡去追這種路徑的東西有點難搞
用經緯儀會好操作些

Meade 的Autostar #494可以到官網輸入ISS的軌道資訊就可以追蹤了(我沒用過)
所以無論是Meade ETX 或是LXD 只要是用#494都可以搞定追蹤的問題(理論上)
Vixen 的Skysensor 2000應該也可以，starbook我就不知道了

所以，如果the sky有提供ISS的軌道外掛，搞不好也可以

剛剛隨便瀏覽後 大致上看到thesky6 官網所提供追非日週運動物體(如慧星，ISS...等)軌跡的方法

節錄ISS 和衛星
Tracking Satellites - ISS, Iridiums and More
Sample AVI movie tracking the ISS Paramount ME tracking ISS unattended

Quick Time Movie - Paramount ME tracking ISS unattended

To track on a satellite first issue a Slew To when you have found it or clicked on it in TheSky then use the option "Track Satellite" on the telescope tab. See below.

Tracking satellite

Track on satellite set rates to match

NOTE: Tracking a satellite is not as simple as a planet, comet, or minor planet. It will take one or more slews to get the object in the field then it TheSky will attempt to micro-slew to the object based on the changing rates in RA and DEC.

Note rates are displayed

Satellite tracking dialog

The star symbol in the center represents the center of the field and the smaller circle where the scope is relative to the target. When the two are coincident the object is being precisely tracked!

 

You can also use a spiral search using Start Search whereby the scope will attempt to find the object if it is no where in the field. If the object is in the field but offset from center you can mouse click inside the square box and the object will be offset from the current position in the opposite direction. Takes practice! This way you can manually center the satellite provided it is in your field. If not try to search for it a second time and make sure you are setting the rates to match the bird. Good luck!

 

Before trying to nail a fast moving bird first make the tracking work with a Geosynchronous orbit satellite. Why? Because they hardly move at all! These are quite easy and fun. In fact you can actually just turn the tracking off completely and these satellites will remain in the field. Even in very small CCD fields. See below image.

嗯~~感謝~
來研究研究~~~~~~~~

已經看出來太空梭在上面啦~
移的的這麼快也拍的到...算是拍的不錯了!!

這麼用功喔
有拍到還亂叫
我根本連看見的機會都沒有

原來炫大會有人造的困擾~~不然恐會被你打下來~~有關單位會找你當顧問 ;D

昨晚 有帶小朋友 還有路人  目視 很亮的 iss

好亮

我朋友問我說~~你是拍到太空站丟出來的可樂罐吧!!?

=_=...........

太空版的上帝也瘋狂 ;D

參考看看

電影影集 不是有 軟體 可以解析度拉高

不知道有沒有軟體可以修正炫大的圖

不過 accord貼的
這人拍的真是厲害
不知道   是否是錄影方式 

還有看圖 好像太空梭還會翻轉

ISS跟太空梭~走過你的位置頭上時~
因你的位置是定點~~看到它的角度本來就會因在天空的位置不同而變化
不是它在轉~是因看的角度問題

850mm+40D
ISO200--1/250秒
比較清楚了~^_^

剩下七次機會可以拍到太空梭跟ISS共舞的畫面了
