Re: 快將復活 -- 30cm F4 Newtonian
Good job!
BTW, can I ask you if you have these Vixen accessories available?
(1) 77237 Corrector PH for R200SS (plus the details of its threads)
(2) 72689 EA 42 to 31.7mm
(3) 72954 DC Ring 60mm to T2-thread or equivalent
Will need details in (1) to check if I need more adapters for my CMOS camera

又一小小貼士
安裝咗 EOS 接環望遠鏡對了焦後,你可以買啲士啤 EOS 鏡頭後蓋,拆下相機(例如用落第二支鏡),然後用布包好望遠鏡之後再用。

Re: PentaxPF-100ED觀鳥鏡
Pentax PF-100ED 觀鳥鏡 $3,000 WhatsApp Julian 98333004 2016年購入, 原作海外觀星用途, 可惜配上天頂棱鏡後便不能合焦。 只在香港用過三次觀星(直望, 沒接天頂棱鏡), 星點在視場邊也非常銳利! 小弟沒有觀鳥, 所以此鏡長期置閑防潮柜內。部分外皮包膠有退色現象, 但光學部分完好。 此鏡有伸縮遮光罩, 亦有原裝鏡袋。它能接1.25”目鏡, 以旋扭式鎖上, 非常方便。 兩支係唔同嘅? http://hkastroforum.net/viewtopic.php?f=18&t=35941&p=311525&hilit=Pentax#p311525
