1. DEW SHIELD I've completed a pair of dew shields for my 16x70 binos. I used a 10mm thickness Mountain Warehouse camping mat paired to some 50mm Valcro with additional strong glue to keep them stuck together. For the first one, I used the full 50mm overlap on the Velcro to hold the ends together but they were quite hard to pull apart. So, for the second one, I used 50mm on one side of the Velcro and cut-down to 25mm on the other side of the Velcro. Time will tell which is the best solution, then I can make up a "third one" to be the same as the best of the other two - if needed! 2. FILTER HOLDERS My APM binos have 20mm of eye relief so I hope to make some filter holders from some of this matting. I have some spare old 2" Skywatcher UHC and O3 filters in the loft, so I plan to experiment to see if I can construct something from the camping mat to fit them over the eyepieces of the binos. After removing the rubber eyecups, I am left with a 2" diameter eyepiece which matches the circumference of these 2" filters. So, I am making a 40mm wide & 210mm long camping mat "roll" that will fit exactly around the eyepiece. The ends wont overlap, they should just meet up and i will wrap the whole thing with Gorilla Tape to hold it "in a circle". This circle should then just push down over the eyepiece to hold the filters in place. I will use some folded over gorilla tape segments to make a "rim" that the filter will "sit on" ( at a distance of 10mm from the top ) when pushed inside. As the 2" filter is way more than the 30mm of the bino eyepiece lens, then as long as I dont block the central 30mm of the filter, the view should be unobstructed. The glue is setting at the moment, if successful then I will post up some pics... (Blue Peter would be proud!) Alan
