當晚大部分的墨魚船都在西貢內海，但對東壩依然有一定程度的影響，目視的銀河沒有以往的光亮。

Happy stargazing~

同obsession比，呢支平好多wor!!!!!!

16" Dobsonian....極度吸引....

我覺得用星圖慢慢手動搵object係觀星既一部份
當成功搵到個object既時候，好有成功感

呢張相係我用TP-1 影過最暗既object
我用既星圖係"The Observer's Sky Atlas"
我覺得跟住星圖啲光星去搵object都唔係太難

尋晚見幾好天，再收集多十幾分鐘光子

Last night's time lapse

To me, I enjoyed last night very much. It was my first time to see DSO in such a high resolution. All star clusters could be resolved easily. I like last night's M57 most. The resolution, color and details are really impressive. Chanlunlun & Bingsze, thanks again for giving me such a great experienc...

多多指教~

模型用既lithium polymer 每Cell電既電壓一定要維持喺3.7-4.2V之間，千祈唔好放晒D電先recharge！！
長期存放時最好維持喺3.8-3.9V，charger最好就係用D有Balance功能既charger，可以平衡每Cell電既voltage，不過呢D charger都幾貴... 幾百到幾千不等...

好靚既玫瑰！~

左下角好似有少少綠光?

分別用EM-10同EM-200追蹤，兩者差異大唔大？
就咁睇呢張相，好似EM-10都好掂wor！
