Yes, Baader Zoom + Paracorr make for a nice night at a dark site.

Bob,

Thanks a lot! You know that "presbyopia" means "old man eyes!" Oh, I've been there for quite a while now. It's really frustrating when you can't focus for infinity or for anything closer than about a foot-and-a-half. Presbyopic and myopic!

And now I find out I can't even focus for the center of an eyepiece and the edge of the eyepiece at the same time, but only one or the other. It's pathetic that the telescope focuser has to do all the focusing for me!

No hobby for old men, eh?


Mike

We are all different in our likes or dislikes. Why no one eyepiece can ever be best. In a Newt w/o Paracor, coma is an aberration I can't fix, so the off-axis is permanently mucked up. With FC, if I am lazy and don't re-center my area of interest, a small turn of the focuser know makes it nice and clear. I don't consider the FC all that bad in the 20XW...and its so little in the 14XW that my eyes can accomodate it. The 14XW is actually my favorite eyepice of all the XWs.




I am with Bill on this one ~ But just for the 20mm XW. I can barely see any FC w/o a paracorr in the 20mm XW, but I see LOADS of it in the 14mm XW w/o a Paracorr in my 10" F/4.7. Others have reported the exact opposite, so I guess it depends on our individual eyesight.

That's why I have an XW 20 but do not intend to buy an XW 40. I've completed my XW collection: 3.5, 5, 7, 10, 20. No mas.
