The Moon near the Sun / 今朝の細い月

07:18 AM; by iPhone XR

今日はプラスチック-ゴミを出す日。偶数月の第一金曜日は、使用済み乾電池も出せる。
両手にゴミ袋を持って店の外に出たら、太陽の近くに細い月が・・。一旦ゴミ袋を歩道上に置き、買い替えたばかりのiPhoneXR(Camera 2+)でパチリ。

EMS housings in the processing

動画は2日前。 今日までに急遽30個加工し、塗装業者に預けました。

Another EMS-UL SET for Taiwan completed!


This EMS-UL SET wit IPD-Helicoid will offer the IPD range of 60(minimum) to 78mm(maximum) at the “D” of 160mm.(60-73 at the D of 155mm for example)

The total light path in this EMS is 166mm at the IPD of 64mm. The larger the IPD,the shorter is the light path.  But considering the margin of 15mm, the back-focus should be secured about 180mm or longer.
