HDF or SDLv2 for MM3
This maybe a simple/silly question but what is the difference between the
HDF (40862) and the SDLv2 (40936) eyepieces for the MM3 scope? Both 15-45x.
Does SDL actually stand for anything?
This would be for an angled eyepiece.
Looking to buy my first scope after having an old 80's Bushnell hand me down for years. Looking at the MM3 or now when it comes out the MM4.
