Wongsir 寫: May I have the wide angle shoots of the 2.4M telescope.
Could you copy the photos in a cd?
Certainly! I can drop the CD to Astrofarm when it is ready. Will call you before hand to arrange the time. :wink:

講到新目標, 我覺得這地方也不錯 -- 南嶺國家森林公園

天晴可以看星星, 天陰可以遊山玩水, 看花賞樹觀鳥. 那裡還有間靚靚酒店, 也附設營地, 豐儉猶人.
Book marked. Will investigate... :mrgreen: So many place I want to go... :P

Try not to use LPS next time. For galaxy or cluster objects, LPS not so effective to bring out the faint details but cutting them off, I think. LT Thanks very much for the advice, LT! :wink: That seems to be my finding as well when comparing the filtered & unfiltered subs. Though I need to do more ...

Thank you for the encouragements and suggestions on objects. :wink: Looking at the image again, I think I've definitely over-done the processing in an attempt to bring out the last bit of signal there. :oops: Have to go deeper or go to a darker site next time...

Subaru: it was taken on my rooftop in Tai Po (near the KCR station).

APO: I haven't graduated from B&W yet! :oops: Too many things to try and problems to solve, no time to try color frames yet.

Got one and only one "astro" shot for the trip. Will cover that later. But quite a few snapshots. Overall I am quite happy about the trip since I learned a lot about astro trips (what to do and what not to do) which should benefit me in the future. The Li Zhiang old city is really charming and defin...

SY Lok 寫:Hope to go there again. I will have a trip for bird and other wildlife in August. :P
What's your plan? Where will you be going? Ideally I would like to have a trip combining astro, bird, wildlife, landscape, food, drink, culture... perhaps thats too ambitious! :P :P
