香港天文論壇

Composed of 4 frames, 2 of them are 25-min exposure and others are 15-min exposure. Lumicon Deep-sky was used. result of proccessing is not very ideal. I will post the better one later.

I have just known that not a lot people participate in the competition this time, right. Whatever the no. of participants and products are least comparing with previous years. Reason?

It is not 墾丁. It's Lulin, a location situated in Mountain Yu.

不如我地聯名出一張...

這…這…這…，實在太利害了！！！
好！這次比賽我也出一張神仙魚試一試，好不好？

Taken with 10" reflector under very poor seeing on 19/03/05.

Amazing!!! Amazing!!! Amazing!!!
Could you tell us the detail about the proccessing?

No 大師 any more. There are a lot of people prevailing over me in HK. Please try the below. 不如大家拿陳大師張slide來練習尋日講既flatfield... Good, but I think Carl has to provide the scan for us to proceed. 陳大師, can you provide a raw for us to practice? I will also provide some scan (tough job as they are heavily vi...

PaulNg 寫:本來是猜不中的...

但左邊紅色那個分明是加洲星雲, 再找找星圖便知右面是ic1985了...

It isn't ic1985.

緊急處理了一不，應有很多改善的地方。先拿出來考考大家。

這是什麼星雲或星區？提示是這張照片是用FSQ106加Pentax67在十二月拍的。
猜得中我就佩服他。

處理得太快，感覺怪怪地。不理了，先送上來讓人笑笑，晚一些再弄一張認真的吧！(語無倫次，是不是有點神經病？)

影像處理的要指是noise的加強程度要控制在剛好可以接受範圍內。而去除noise則不能太影響影像細節為主。抱歉這張的noise去除得有點太過份了吧？
還有，Paul 大少你什麼時候才上傳詳詳細細如何scientified的根據Histogram處理偏色問題？

PaulNg 寫:平順去noise版:

PaulNg 寫:看historgram就可以了

請詳細告訴我怎樣在historgram看到偏色問題，事先要不要選取適合的'Proof Stup'？快說，要不然我掐死你喂kangaroo！！！

PaulNg 寫:發現陳大師的process有一個特點, 就是green channel粉強的, 把天空弄得綠綠的...

這是小弟調整過後的樣子:

原照巳調整過偏綠的問題了，用我的monitor看好像沒有不正常的綠，看來要用我的CRT試試看。又或者從前看HG400和SuperG400的照片太多，慘，難到我有色肓！！！
