獅子座NGC2903

昨天透明度很差, 好在入夜無起雲, 可以試吓用支10"鏡影.

左面是北.

Yes! The transparency was really bad & I gave up the outing. Tonight both transparency & seeing were bad. But I went out for testing. Anyway, can u share with us what software u used to process the image?

[社長]

恭喜開光成功!

在這片幅下或許不能說明太多，最多證明望遠鏡光學及機械工作正常，而且拋物面鏡就是那樣簡單的東西。

看到1150mm焦距的威力，可以想像日後會有更多精采作品，期待更多佳作

我也運了一台CFP 200 f4碳筒鏡到西藏，架在HEQ5 Pro上招呼朋友的，又有LVI導星器，到時接部單反上去便可以拍。

[funoooo]

這樣環境都拍到，利害！利害！

我就白果王了

I use Nebulosity & PixInsight to do the majority of processing, and then Photoshop on final touch.

原來我位CFO的朋友是社長在西藏居住的師妹, 如果有CFO support, 到西藏一轉就比較容易成事. 不過今年的工作實在繁忙, 看來要攪掂d工作才可出外影星.

到西藏拍星野或星流跡很簡單也很漂亮，但拍深空是完全另一個故事，運送器材、在高原下熬夜等，跟平地甚至台灣武嶺比較，工作量隨時要下調70%才成，唯一的可能性是像我一樣有固定觀測站，在台內拍攝，或架好器材移出去空地才成。

我不是說把望遠鏡赤道儀運到納木錯湖畔拍他三五七個晚上是不可能，但經驗11月建台至今對當地觀測條件又再進一步體驗，我說那是一件很苦的差事，甚至有些許危險性。

The weight of this CF250 is over the limit of HEQ5Pro for imaging. Otherwise I will be in trouble.

[社長]

no, I shipped CFP200 to Tibet, not 250, focal length of 800mm at f4 is good enough for me (and friends).

200 is much smaller than 250, HEQ5 Pro is good enough.

Can u share with us,why two softwares, Nebulosity & PixInight, are needed?

我相信是, 特別是在5000m在高度下, 加上西藏的綠化比台灣高山少.

It is just a matter of handiness. I think calibration by Nebulosity is easier, while processing with PixInsight allows more flexibility.

I can use just 1 software to do it, but I have both, and can do around these 2.

I think the CFP200 is well balance between handling and light gathering power. It is sufficient for most of the amateur DSO imaging work.

The reason I buy the CFP250 is to surpass my limit with the 8" class.

台灣最高才4000，以一般人能達到的3000多計，也肯定比西藏的同海拔綠化好得多。

又奇怪的是，我可以在阿里的4300長期生活，睡得好吃得香，但羊八井附近的4300我總有點反應，我也很懷疑自己在納木錯能否過夜。
