Taurus T400 on the Titlis
Fig. 6: My Taurus T400 Dobsonian on the Titlis. Actually a super telescope for deep sky and also planets, but the spontaneous, violent gusts of wind on the Titlis did not tolerate it well: It is too light and is pushed away by the wind. So the next time I took my short, heavy 300mm f/4 Dobsonian with me. It's more stable in the wind. iPhone 8; Δt=1/3004 s; f=3.99 mm; f/1.8; ISO 25; 9 October 2021 16:43:40
