Issues / Suggestions for improvement

• Unpredictable crashes / freezes: More than every fourth session, my GEM28 suddenly no longer reacts to guiding signals or hand controller commands. Only a restart solves the problem
• During cold temperatures (<10°C) the hand controller display becomes very sluggish and difficult to read.
• Check the upper tripod screws regularly. On my tripod one (of three) screw is often lose (1.5″ standard tripod).
• iOptron does not supply a hand controller bracket (Fortunately, I can use the bracket from my SkyWatcher Explorer 130p)
