  Cleaning shades and mirror?
Posted by: c_davidson - 12-14-2015, 03:45 PM - Forum: General Topics Here - Replies (6)

The filters on my sextant are getting dirty/salty.  What should I do to clean them?

How about cleaning the index mirror?

Is there any concern about scratching the filters or the mirror?

Do any of you have pictures or plans of an Artificial Horizon you've made?

I want to make one and it would be nice to see other examples.

What fluid do you use?  Water or oil?


What kind of glass should be used?

Does anyone have a form they use for sight reduction that they could pass along?

I'm trying to create one for myself but would like to see what others have made to get ideas.

Thanks,

Craig
