E200和DSLR

[Subaru]

I like this 獅子座流星雨 photos the most!!!!!! Regardless the grain size, the composition, color, feeling is the best!!! Very touching one!!!

還有一張. 假如我用Press800會好一點, PJ800的微粒太粗了, 可藉機會已過.

獅子座流星雨20011118 18:27-18:42UT, 16mm f/2.8 魚眼鏡, 柯達PJ800負片, 曝光15分鐘.

That is so great!
Sometimes I am thinking, for widefield astrophotography, it is very difficult to have good composition, as through the viewfinder, no matter how bright it is, it is still very difficult to recognise the stars positions for composition like what we do for daytime photo.
I am considering whether we can use some metal wires to make a rectangular frame on the top of the SLR, and then through that frame we can predict approximately what position of the star field we are taking?
Thanks for sharing your great photos!!!

好漂亮的又一張傑作
介不介意讓我來當桌面背景啊？
請問
Press800和 PJ800分別又是什麼來的？
和E200有什麼不同？

Thanks, that is it!
In chapter 7.1.7, it said "在機上（閃燈插座處）裝上一個外用觀景器"
any more information about this 外用觀景器?

我記得上黃老師0既攝影堂時見過一張 slide 有個"外用觀景器"大概0既樣...
但係詳細點整就唔係好知呢.

我淨係諗倒可能用塊亞加力畫番相對0既 28mm, 50mm, 200mm 之類0既框框, 再睇下點套倒上去閃光燈個位咁啦.

I also thought we may use 'ar gak lik' to make that, however not sure if in windy condition, it will catch the wind easier or not... So I may thinking to build one using metal wires this weekend. Thanks a lot for the suggestion!!!

Make sure there is no parallax issue with the external 'framer'. However, I don't find these additional devices a necessity, as my camera used for astrophotography were entry models with normal matte screen. I can still see the bright stars for framing (with lens or prime focus). Practice makes the difference and you will soon adapt to it.
