My 24mm Burgess binoviewer arrived today.
They came in a nice metal case. Also included were two 20mm BO Bino-Lites, an OCA, a par-focal ring, and an extra 50mm nose piece. The standard nose piece that comes on the binoviewer is 24mm in length. The extra nose piece is not an extension, it is a replacement for the existing nose piece.
I assume the purpose of the longer nose piece (when used with the supplied OCA) is to help you reach focus in a Newtonian telescope. The supplied par-focal ring is probably there to help you save your diagonal from abuse via this long nose piece.
I have horrible skies here now but I was able to get out around noon for a little solar observing through the holes in the clouds. I found the Bino-Lites to be very acceptable EPs for anyone who is just starting out in binoviewers. The are quite a bit better than the 26mm EPs I got with my first binoviewer.
The binoviewer came with the same three screw setup as the BV125C. Burgess says that the self centering EP holders will be sent out later at an additional cost of $40. (The unit cost as is shipped to my door was $259 plus $8.95 shipping for a total of $267.95)
The diopter adjustment is much nicer with a better feel than what was on the BV125C. One and 3/4 revolutions of the diopter adjustment gives you the total 5mm of travel.
In size and weight they appear identical to the BV125C unit. ( I did not actually put them on a scale, I just held them in my hands and I could tell no difference between the two units.)
So far they seem pretty nice. I took a business card and cut it to 24mm and stuck it down to the optical window. There is 24mm of clear aperture up there. I was curious about that. The optical windows of the BV125C is around 3 or 4 mm smaller. Just looking through them you can see it is a bigger prism.
So I now have a new binoviewer, a new power wheel, and a new 80mm Fluorite short tube that will focus any binoviewer in the known world. I also borrowed my nephews Bino Vue.
I will be playing with my new toys for a while.
