自作45cm ニュートンの反射望遠鏡の掃除と調整を行いました。一人でも出来る作業ですが友人の石井氏の応援がありスムーズに終わりました。光軸が狂い易いのが欠点ですが、毎会の調整は自作なんで仕方ない!
I cleaned and adjusted my own 45cm Newton reflector telescope. It can be done by one person, but it was finished smoothly with the support of my friend, Mr. Ishii. The drawback is that the optical axis tends to go wrong, but it is unavoidable that adjustments at each meeting are made by myself!
