Hi

a couple of simple questions.

Are eyepieces always inserted onto the holder (focuser, barlow etc) as far as they will go? Sounds like a dumb question, but I have an Ultrascopic which has the "locking groove" located towards the bottom of the eyepiece tube. So, for this to engage with the locking screws on the holder, it is not fully inserted.

The other question is to do with the eyepiece holder. Are they designed to carry the eyepiece resting on the bottom with the locking screws at 10 and 2 o'clock or at 9 and 12 o'clock, or it doesn't matter?
Thanks
