Description

The PI has been touched for more than a year., took the old photos and re-work it to see if there is any progress....

Use the PI instead of using the DSS, the effect is quite good, and inadvertently found a way to make the "Star Point + Nebula" Mask.

舊圖重修之 NGC2244 on 2017.12.23-24 @ 鳶峰

FSQ-85ED 直焦 / Canon 650D改 / Vixen SXP / M-Gen + APM60240 + AU+60240



ISO 1600 / 300s x 40 + ISO 1600 / 180s x 46


Flat (珍珠板人工平場) / Dark / Bias 若干張



PixInsigh 1.8 / Photoshop CC 2015 / Camera Raw

邊緣稍微裁切

想說 PI 也摸了一年多了,就把舊圖拿出來重新練功,看看有沒有進步....

此次捨棄方便的 DSS,改用 PI 疊圖,效果還挺不錯的,且無意間又發現了製作「星點 + 星雲」遮罩(Mask) 的方法。
