scope time
first I tried to disassemble the front lens. I don't have the special tools required for that so I gave a shot to that
however, it seems that the scope got a shock and the lens mount isn't circular anymore. I got the bolt almost out but I had to screw it back or ruin anything. I got worried the anti glare coating on the lens will go away will the stripper but since acetone never ruined my glasses I gave it a try.
I disassembled first a smaller part that didn't have any optic in it an tried my PC stripper. Worked like a charm in seconds. I put a silicone plug in the exposed part of the inside of the scope to avoid the jelly stripper to get in and I immersed the scope.
then I noticed a screw that locks the lens ring.
however, after trying my mocked up tool, the ring wont come out. I now have to hope it will accept the 200°C of the PC cure. A simple kitchen glass withstands it so I'm not really worried.
As for the A2 model, it has, like I said, a little light bulb attachment on the top. I put a white led there to test : it lights up the azimuth scale engraved on the glass inside. I left enough space between the ring and the lens to eventually insert a red filter to make a canon reticule. I really dig a scope that lights up inside ! I'll grab some power supply from the hengsler counter to drive the top led.
