I think I saw this image in the big telescope!
If you look through the 51cm reflector, you can see the stars in the sky. I could see so many stars, it was amazing!

Perseid Meteor Shower and Astronomical Observatory
2020-08-12.13 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.

Saturn August 4, 2020
Saturn 2020-08-04 It is wonderful to watch the inner C ring that looks into Saturn when seeing is good with a large telescope. ASI224MC+ADC is easy to take image if I know how to take it. This is very different from RGB composite imaging.
