Time is always limited! I went Gemini Observatory in Lijiang, Yunnan, China, this Chinese New Year. Without much preparation, the trip was tough, but enjoyable. However, I don't have enough time to process the images. I only processed these two after more than a month.

整個暑假快要過去,沒有一晚晴天能令天文愛好者樂觀,直至29/8/2017該晚的天氣預報是沒有雲的,雖然當晚的煙霞較大,但是沒有雲也可以作練習。懷著練習的心情去北潭涌拍天文照。今次天文台早於兩日前已預測29/8/2017晚的天氣會是晴天,她的預測相當之準確!但對於天文攝影者來說,還差一點大氣透明度,無論如何那晚就造就了這幅眉月星雲 NGC 6888天文照片。說到這幅照片,其實是第二版本。原本的第一版本給一些朋友評論後,我才認真處理過這個張第二版本,因為心裏面只想北潭涌收集返來的數據只是一般質素,所以在處理第一版本時,只是隨便處理就算了!沒有多花心思…
