dreadful focuser

Posted By David Johanson

I have a JMI NGC-DX1 on my Intes MN56 and I love it.

A few years ago I upgraded the fence on my Delta table saw to a Unifence, several friends told me it was overkill for the amount I use the saw, but everytime I use the saw I am thankful for the precision of that fence. I have the same feeling everytime I turn the JMI.
There are certain things in life that everytime you use them a smile just appears on your face, the JMI has that effect on me.

Ii would, however, try the relube before dropping $250+ on a new focuser...

TV 41mm Pan or Pentax XL40W XW -- help me decide

Posted By David Johanson

I have a XL40 (not XW). It is a marvelous eyepiece. The view is gorgeous in everthing from a 80mm f/6 Blackhawk @ 12X to a C-8, @ 50X. Nearly perfect views from edge to edge. I understand the XW is even better.
I've never seen any Panoptic above a 19mm, which I own and love, just thought I'd take the opportunity to say how much I love that 40XL...

Re: Safety undercuts

Posted By David Johanson

The undercuts are like the "safety dropouts" on the front forks of most modern bicycles. The prevent the front wheel from coming off unless the quick release is loosened considerably more than just flipping the lever. I curse it everytime I pull a front wheel.
I would like them better if every one had the same indent or none. It's annoying unscrewing a quarter turn to pull one eyepiece then screwing way in to secure the next.
