咁高倍，用8" dobs都影到耐，可唔可以分享下點影？

我同幾個朋友研究緊，遲D都想買枝12" dobs玩下。

其實唔係好高倍, 8" f5 = 1000mm, PL 10mm 目鏡, barlow ~2.5x, 相機a75鏡頭係F=16.2mm.............計計埋埋............
1000x2.5/10x16.2=4050mm
加上a75 ccd size 係7.5mmx5.6mm@movie640x480,
比較c8+toucam(3mmx2.2mm cmos??)應該係低倍喎!?

"點影？"

......就咁影囉!!! 寫曬出黎囉喎!?
不如睇下小弟o既短片先

從頭再stack過, 因為漏o左一個 avi 冇處理到!

今次踢走埋d blur blur 地& 云云地o既 frame, 只處理754 frame

size 100%

唔知點解, registax 調layer後, 出o黎o既感覺好似好高反差咁o既!?
o個兩條"電車軌"好深色呀!

調高gamma值會低少少反差.
以你呢種人肉追星影成咁,都真係好勁! 自愧不能.

& shows the image quality which is direct proportional to the cost !

Really don't know how to vote!

True. Therefore this competition is rated by image quality / cost.
The idea is to see if the huge difference in cost is justified by improvements in the resulting image quality, and to what extend the competitor's skill can narrow the difference. I think the organizer should make this point clear.
