星軌拍攝技巧 數問 -

1).數碼機因hot pixel而唔適合曝得耐...最好分開影影夠幾個鐘...咁每張間隔之間都要俾CMOS斗下氣?
有師兄 教過 分十幾張 每張 10-20min 再合成 好過 一野 暴 幾粒鐘, (菲林 令計)

2).數碼機有D人話用ISO 100、有人話用ISO 400-800好...如果用合成方法...其實係咪都係就番光害而定...定係關雜訊事?
睇天氣 , 小弟 用 o個次 用 iso 100

5).北極星仰角澳門係23度,咁香港一樣??
4季 都唔同 位置, 用星座 搵 會準確 d, e+ 係 冬季, 北極星 位置 係 獵戶座 (lei 個最易 認, 唔會 搵唔倒 ... ) 頭頂 (腰帶 致 頭頂 距離 再過 5倍左右)

附圖 係 舊年 去雲南 香格里拉 時影, 本泥想 長暴, 不過 o個晚 太涷 個人 頂唔順 要收皮 反酒店

=====
這張是11月15日凌晨拍攝的M42獵戶座星雲, 大埔的光害較嚴重, 所以要加上IDAS V4濾鏡作長時間曝光, 分三段不同時間曝光及作Layer Masking 處理, 把動態範圍拉闊. 在月光的影下算是滿意, 希望之後可以分數晚作10小時以上的曝光並加長每一張frame 的曝光時間 (現在是5分鐘一張), 使到暗位的表現進一步改善.

7. I think I know why I admire micro-ISVs.

Some of my fascination with micro-ISVs is rooted in my wonderings about the path of my career over the long term.

When I was 22, I believed that I could write code until age 65. I saw no reason why I could not be a software developer for my entire professional career. Some folks told me that being a coder is a burnout job, but I didn't believe them.

I am 36 now, and I think I have a better understanding of things. I am starting to realize that someday I may actually want to make a career change. I am trying to picture myself running an ISV when I am 55, but I just don't see it. Running a company can be awfully stressful sometimes. Will I still want to be doing this in two more decades?

My prospects for a second career are bleak. The cold reality is that I only know how to do one thing. Instead of looking for a second career, maybe I should be looking for a way to stay in software.

This is one of the things I like about micro-ISVs. The lifestyle looks very different. The workflow looks like it might be a lot less stressful. Running a micro-ISV looks more like a marathon and less like a sprint.

At my recent lunch with Thomas Warfield (Pretty Good Solitaire), I asked him if he thought he could still be running his micro-ISV at age 50. He said yes. Warfield is 40 now, so this is not the perspective of a naive young person just getting started. I believe him, and his answer makes me wonder if somebody I will be running some sort of a micro-ISV as my full-time job.
