自作45㎝反射は夜、星が見えず正確な光軸が合わせる事が出来ない! イライラです。
日中、友の手を借りザッとを合わせた。夕方、薄曇りの悪条件ですが初土星を観望。45cm反射260倍、今の時期の土星イメージとしては 好印象! きっちり光軸を合わせたい❗
The self-made 45cm reflector not frustrating at night, and the exact optical axis cannot be aligned! *During the day, I borrowed my friend and got together. In the evening, the first Saturn is observed although it is a light cloudy condition. 45cm reflector x260 , a good impression as Saturn image of the present time! I want to align the optical axis exactly
