I could watch the vivid solar prominence at the brief moment of the break of the cloudy sky through the APM120SD-BINOCULAR for the first time.
82mm UV-IR-CUT filters have not arrived yet, and 52mm filters were substituted.
Through the slightly cloudy and with the temporary small aperture, I could even see the vivid and thrilling prominence that appeared toward the north pole. I am so impatient to see it through the larger filter(82mm) next time.
Anyway, I could ensure that this total system offers fine H-alpha solar image, which I believe is a epoch-making result.
A counter weight shaft will be set on the extended line of the handle rod, which is the necessity to cancel the additional load of the COMBO-QUARK and others for H-alpha solar observation. I am going to make the tuning fork shaped extension on the handle rod to accept this weight rod.
The epoch making challenge of watching the Solar Chromosphere and prominence through a commercial binocular will possibly be successful very soon.
The movie above is the 82mm filter thread made on the dew-cap. R2 filter and UV-IR cut filter will be an equivalent of the ERF for the COMBO-QUARK.
