I own a tv85 which I love but often desire another Televue scope with more aperture the great TV focuser. I have looked into the NP101 and some people have told me in colder climates during winter and fall useage the images are blurry until the Petzal lenses equalize. Is this true or false?Also if dew forms does it form internally in these elements?I have been told a number of these scopes have sold on Astromart due to this coodown problem..if it exists.My question by no means is to flame this product, only to find out from users if exists..so I can grab one.
Also as a secondary issue do the focusers on these scopes come with some built in friction without adding pressure via the focuse lock knob?My tv 85 is buttery smooth but is too loose from day one.I spoke to the good folks at Televue and was talked out of sending back..I agree the collimation is too good to screw with. But if I did this over I want more built in focuser tension. I want to know how owners found the tension on the NP101 focuser?Does it make a difference..you bet with huge 2 inch eyepieces. I would value any opinions owners have regarding my question.
