    I don’t think you’ll have trouble with a reasonably high Sun although it’s true some sextants have less dense shades for the horizon mirror. 
    I found this was quite useful for deciding which Sun was which.  The ‘gotcha’ for me was observing a lowish Sun.  I found I needed quite a large tray of liquid so that the Sun could get over the sides onto the liquid.  My plate glass mirror is also pretty big coming from the inside of an airmen’s’ locker.  With such a situation there’s a lot of ducking and weaving your body to get inline with the centre of the tray and the Sun.  Then it’s quite easy to get full blast of the reflected Sun from outside the shades like driving down a wet road into Sun.  When you go inside, your vision isn’t quite right, funnily enough it’s shade green colour, and you think you’ve done permanent damage, but for me it’s always cleared up within an hour.  DaveP
