Hey guys and gals,
As some of you may have seen, I now have the sextant
described in this thread:
Strange Russian Sextant - Question
, a modified CHO-M.
However, it seems that the index filted is severely inadequate to handle the sun, being only as dark as some sunglasses. I found out that CHO-M fiters are out of stock from where I planned to buy them, so my best bet is to now modify the filters myself.
Now, as a solution I thought of, some sextants I saw have double polarizing shades to control the amount of sunlight and glare. However, to my knowledge, viewing the sun through crossed polarizers, during an eclipse for example, is a sure way to damage your eyes and always advised against. Was/is this configuration safe in a sextant
? I plan to attach two 46mm camera
polarizers on the shade (which luckily has an outer diameter of 46mm) and rotate them to adjustg light intensity. Am I missing some critical element in the filter assembly?
The other solution will be to attach a 46mm camera
filter on the shade and screw on it interchangeable 46mm filters of varying density, one of which will be weither a Baader solar
filter or a circular shade 14 welders glass.
What do you guys think?
