Hi Brianmac, I use the Burgess Optical binoviewer on my LX90. It seems to perform well. But I suspect that it is much lighter and probably has a narrower optical path than the Denk you are thinking about. I find that my binoviewer is fine for 20mm series 4000 EPs (52 degree aFOV) and BO 17mm WA (67 degree aFOV). But if I go for a much wider tFOV than that, I start to see a little vignetting. I think your Denks have a wider lightpath - and so vignetting will be less of an issue. But the Denks are expensive :(

BRIAN MAC My binomate is the same as the burgess, I use it on a 120mm refracter.and to get low magnification i had to cut the tube down 55mm to get focus without using a barlow, witch took it to 4x making 20mm 200xmag. now i get 50x with a 20mm plossel,you can screw a 2x barlow onto your eye piece or onto your binomate and obtain 3 different powers with 1 eyepiece. Now i have a long out focus and use a 2" mirror to shorten it.so as to use single eyepieces. My dream is a 2" black night binoviewer(£900),dream on brian! BRIAN.[:D][:@]

I have the denk bino, It really is outstanding on the planets in my F7 130 Apo the detail with 2 eyes in the denk is well worth the extra cost.

Hi Tom, i will have some denks one day?[sm=rolleyes.gif] but at the moment i fancy a look at the big binos with changable eye pieces and 45degree angle, it appears that you can use barlows on them,up to 100 plus mag. They price at about 900pounds[:@].Anybody know anyone with any,and what are they like?[i] BRIAN[8|][/i]

The problem seems to be the weight of the bins 16 pounds so you need a good mount And also the cost of eyepieces 2 of everything.

Hi Tom, Thanks for the info, Can you tell me where you bought your denks from, I have have searched the net for an english dealer but drawn a blank.you can get them direct from denk but do you pay a massive tax on them? BRIAN
