eye relief??? It's a peep hole.....you need to place your eyes very close.Canopus Lim wrote:What is the 'eye relief' of the sight tube? Is this Catseye system user friendly in pitch darkness?
I do not like to use the cheshire because it is totally not usable with glasses...which defeats the purpose since I cannot even see the donuts and reflections clearly and hence it is impossible to make a good alignment. Not to mention there are parallax errors with the cross as it is not fine enough.
Umm...yeah..dun think it's friendly enough for those with glasses. Wear contacts can la.
Doing it at night at the field is easy though.....just need a torchlight and shine into the primary mirror.
