367:Comet Neowise コメット　ネオワイズ　C/2020 F3 – 2020/08/04

Comet NEOWISE (C/2020 F3 NEOWISE) and a California redwood tree 7/18/2020 @22:00 PDT, from the backyard, Sunnyvale California USA. The equipment is Sigma 150-500mm zoom at 150mm with Canon EOS 6D, mounted on Star-Adventurer, and the camera setting is 5 seconds exposure, ISO1600 F/5.0. Photoshop CS5 is used for processing. 明るいコメットなので、にわとり。街灯とご近所さんの門灯の光を避けるのに四苦八苦。

364:30 cm diameter Newtonian Reflector – ニュートンの反射鏡　 – 2018/07/29

It is a kind of dream to put up a heavy powerful telescope. I tried to load the 30cm Newtonian reflector on Celestron CGEM by reinforcing the tripod with the spreader. ドブ用のニュートンをセレストロンのCGEMに乗せました。無理筋かもと思いましたが、三脚をスプレッダーで補強すると、剛性が上がりつかえそうです。風には弱いので、将来別補強いるかも知れない。
