買望遠鏡問題,請幫忙
1-小弟想買一set望遠鏡(約HKD10000),其用途為一般觀測星空(有少許經驗);及賞試天文攝影(沒有經驗),想問請各位天文界的師兄/前輩有什麼望遠鏡可以介紹給小弟作以上用途。
2-而小弟家中有Nikon D90,可否作天文攝影??請各位天文界的師兄/前輩指教。
希望各師兄/前輩賜教,小弟萬分感激。

Nikon D90用作天文攝影應沒問題,你可看看以下的POST:

還在乎有沒有車... 有車可以重一點都應付得到。
Nikon的機內filter, 會阻隔大部份的Hydrogen-alpha光諎線, 而那是發射星雲(emission nebula)的主要顏色光。但拍反射星雲(如M45)或星團類, 問題不大。
一萬元(包相機及改機、濾鏡等)的可拍攝組合, 小弟在http://www.hkastroforum.net/viewtopic.php?t=18543出了題目, 到目前還未有人(包括我自己)答得到。
參加觀星拍星活動, 取經驗及與眾同樂是好的, 但參加者大多數的攝星組合, 價錢都是兩倍以上, 那你要小心「中毒」

An option is Skywatcher EQ5Pro mount (not HEQ5Pro) with a 80mm refractor (There are lots of choices for such refractor, including skywatcher). This set up can be $11000.
If you are really serious in photography and interested in long exposure pictures, add an LVI guider which is just $3000, you'll be getting good photos in no time with your nikion.
So the whole set is just below $14000. It will be good for BOTH causal viewing and photography, rather than just photography.
Of course there will be many other opinion on this question. I also agree that it is best to join some star parties first. But I should mention that very few people in HK use the set up suggested above, and you are more likely to see much more expensive set ups in star parties. Do more thorough research on the web and try to get different opinions before deciding.

LXD75小弟也在使用, 好處包括:Monocerotis 寫:非常感謝以上各位師兄/前輩的意見
車方面可以問朋友借(有90%借到 )
觀星地點方面想去萬宜水庫,同附近一個比較黑既球場睇
另外想問各師兄/前輩會何時舉行觀星拍星活動??讓小弟一睹各位師兄/前輩的工具及取經驗
另外一問,小弟在巨眼中睇到 MEADE的8" LXD75 S-N TELESCOPE W/AUTOSTAR UHTC套裝,各位師兄/前輩有什麼評價??
因為我想比較一下
Thank you
GOTO十分準確也很易使用
十分省電, 8個D電可用60~70小時, 4Ah水電用兩晚都沒有問題。(SkyXXXXX就是出名的食電怪)
可用PHD、Envisage及LVI 2等自動導星
很多人用, 所以很多人會教你怎樣用
壞處是:
聲浪較高
不時有人叫你升呢。
最近有人用優惠價賣二手: http://www.hkastroforum.net/viewtopic.p ... 846#195846, 可考慮。
SN-8據外國的使用報告, 是個好鏡, 但它十分笨重(應是十多公斤), 很難搬運, 去萬宜絕不適合。
