"Safe" use of eyepiece sun filter

Hi All,

I have a 0.965 eyepiece sun filter.

As these sun filters are unsafe when deployed at the eyepiece end (ie, they heat up, crack and we go blind), I've decided to test and fit it (securely) at the objective end of the 5x24 finderscope instead of destroying it with a hammer.

Tested it on the sun, it works great, clear solar disk (the camera fails to focus clearly and overexposed the sun).

Photos attached.

Now I can use this "solar" findescope (with cross hairs) to aim my telescope (fitted with a glass solar filter for observing the sun), instead of capping the un-usable finderscope (or burn a circle in the forehead if uncapped) when observing the sun.

Clear skies,

Bill
