I am very pleased to meet RoboScopes.
I don't know if anyone from Japan is participating in RoboScopes, but I can't find any blogs or homepages written in Japanese that introduce RoboScopes.
I would be happy if I could introduce RoboScopes to Japanese people.
My first RoboScopes experience was getting an M31 at Pier 5.
The exposure time at this time was set to 30s, 45s, 60s, but I would like to solve the problem that the central part of M31 is overexposed and the outer edge is not wide enough.
I think that the lack of spread can be improved by extending the exposure time, but how many seconds is better to avoid overexposure?
