Osservazione del 17 Novembre 2012

Primi test osservativi con binocolo Garrett 20×80 WP-CF Mk II Oggi finalmente sono riuscito ad utilizzare il binocolo con qualche soddisfazione. Prima di tutto ho diaframmato il binocolo a 20x60mm, per via del cielo troppo chiaro ho voluto provare a diaframmarlo. Il treppiedi lo ritengo appena sufficiente per lo strumento, troppe vibrazioni con un vento […]
