don't let the cold spoil your view!

When these cold nights bite and that crisp clear sky is upon us you van guarantee moisture will form all over just don't let it form on your lens or mirrors as standing with a hairdryer at 2am in the morning will provoke your neighbours into world war 3. For the price I didn't think these dew bands would be upto it since they run on 5v usb ( I have the largest 480mm ) but on full power it pulls 1.8 amps and warms up quick which i found me holding to warm my hands at one point. Well made with a branded usb cord and a separate power control lead, a tip for svbony which is a positive criticism would be make longer versions for larger telescopes ( even if it has to be a dual usb as I cannot see anything over 50mm running on 5v ) and consider red leds on the controller to save our night vision ..... I would recommend these dew bands to anyone who wants to stargaze into the early hours or on the coldest of nights when dew can form and mess up your viewing .... well done svbony yet again you have impressed me .... thank you for reading my review (scivideos) barry
