Hi guys,

Today I received my 160FL.I was really excited and ready for the first light but I couldn't loosen the eyepiece collet locking nut.I even tried strap wrench but I wasn't able to loosen the locking nut.I'm wondering there is anyone who has an idea to help me.

Thank you.Donghun

- strange, not familiar with such problem. Usually it goes easy by turning it by hand CCW colletsleeve (6-13) to remove 2" plug. Could you try to loose 6-11 end cup locking screws (page 3 of the APO160 manuals) and unscrew the end cup. Than try to push out the 2" plug from inside? You can call us 303 273 9322 (upto 6PM) when doing this. Yuri

Yuri,

I'm not with the scope right now at my work but I was trying to turn 6-12 locking nut CCW.I don't remember 6-13 is exposed outside to turn.I will try to push out the plug (I tried last night this and it wasn't possible with hand).

Thank you.Donghun
