    Which Baader Solarfilter for Ebbco sextant
    From: Herman Dekker
    Date: 2016 Mar 27, 01:48 -0700

    The filters on a Ebbco sextant has become useless.
    I want to replace them with Baader Solarfilter.

    In The Netherlands I can buy two different foil types on A4 format.

    ND 3,8  the LT (Light transmission) = 1/1000
    ND 5,0  the LT = 1/100000

    Which is the most usefull?

    Regards,
    HermanD
