I just wanted to share my initial reactions to my first ever BVing stint. It was super-short (just about 15-20 mins before clouds rolled in). It was in a heavily light-polluted city, & I didn't have filters in. But O. M. G.
I'd gotten a pair of Carl Zeiss Deluxe BVs from Denis Levatic, and also separately tracked down a pair of E-PI 10x/20 Zeiss aspherics (25mm f/l). Finally got a chance to use the combination this weekend for a short stint. Just set up an alt-az mount, looked for some stars and pointed the scope.
Honestly it was like floating in space! People talk about Naglers giving a porthole experience, but the BV feeling is so immersive, that it's almost like visual astronomy was being reinvented then & there. These weren't even rich star-fields, but the feeling was amazing. In fact, my mind v quickly also started wondering that if this is what it feels like w these EPs, what would the FOV of Nagler 13s feel like? So much so that I may have to ditch my old & beautiful 12T2 for a pair of 13T6 (b/c I'll never get 2 hand grenades side-by-side on the BVs!).
I am really looking forward to a proper stint with them, on the moon, the Sun, the Pleiades, Orion nebulae to start with. Things could never be the same again for my visual practice. And that's even before I get to a dark site
I'll stop wittering on now, but boy oh boy - if anyone is reading this while they are thinking about whether to BV or not, you've got to give it a go!
(PS - what do folks use for their short f/l EPs? I've got 2x40mm TV plossls, the 2x25mm Zeiss aspherics - my thinking was to go down the 2x13mm Delites route but I'm seriously thinking about changing that now. For even shorter f/l what do most folks use - I was thinking of 9mm or 7mm Delites (since these will be for more magnification, is it better to go for the better transmission of Delites or would larger FOV still make a difference at those powers too)?)
(PPS - Denis has been excellent throughout - prompt, objective, lots of tips & recommendations. If I could buy more BVs I would happily do so, but you only really need one, right? And I also have to say thanks to Eddgie b/c his thread & feedback on tracking an optical path & thus image sizes in BVs was v helpful)
