Frankly, that could be the best shooting star pix I have seen so far. :-) Is the orange light on the background of the shooting star caused by the frame and residual of itself?
Thanks a lot for sharing! :D

From the outlook of the Orion electric focuser, it should be the gearhead DC motor. Sometimes I have a doubt... in order to have the speed reduced alot, we use gear box, which will increase the output torque significantly also. Will this torque be so big to destroy the focuser when it came to the ex...

Good try. :-) Add oil! You can do it.
Looking at your photos, I have one composition in mind. It is if the window frame replaced with some plants (flower) as an out focused shadow, the scene would be a real nice one...

:cry: :cry: :cry: :cry: It is ... TOO BEAUTIFUL lar!!! The nebula is so firm that we can't wrap away with our hands... PS - I like the first processed photo. Even though it is softer slightly than the 2nd one, the detail still very clear. (In the horsehead region, 1st one's detail even more out than...

Comparing Subaru's widefield photos, they are even better than my "photographic atlas of the stars"!!! The color of the stars, details... all better. I really should learn more from Mr. Subaru and Mr. Kingarthur's photos as widefield is really my favourite! :) By the way, 5 mins + 5 mins can already...

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!!! 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...

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?

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 conside...

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!!! :cry: 原來是這樣 :lol: 那如果是照流星 什麼非林最適合?所謂的高速非林 是指普通的400度相片,還是其它的? 我用普通的400度照,有很多粗粒出現 影流星, 除火流星外, 菲林越高速越好, 因為一般流星飛得很快, 要高速底片(ISO400)才影到. 高速菲林的微粒問題, 這個沒有辦法, 這是菲林的特性. 你可選用富...
