栃木県那須峠駐車場。
今回の栃木県天文同好会の観望会は天気が悪く、雲間から１０個のみで残念。会員の中神さんが自作の５１㎝ドブ、会の３１㎝ドブを使いのDeep skyを楽しんだ。５１㎝ではM8,17.18、27、網状星雲などはホント、色なし画像が圧巻でした。51㎝口径と良い空であれば見える天体に感服しました。

Perseid Meteor Shower and Astronomical Observatory. Tochigi Prefecture Nasu Pass Parking Lot.
This is the Tochigi Astronomical Club meeting. The weather is bad, and I’m sorry that there are only 10 from the clouds. Mr. Nakagami, a member, enjoyed a deep sky using his own 51cm doubsonian telescope and the group’s 31cm dobsonian. At 51 cm, M8, 17.18, 27, net nebula, etc. were really, and the colorless image was a masterpiece. It was a celestial object that could be seen if it had a diameter of 51 cm and a good sky.
