Yes, the angle of viewing is the big concern. Actually i'm kidding myself. I have neck spondolysis, this would be very uncomfortable for me. Pity, as its an affordable route compared to others.

Also Baader IV binos with zeiss prism have come up for sale over here. At about 145mm light path, this is another solution, but way too far off budget. How frustrating!

I'm coming in a little late on this but I have the Baader Maxbright binoviewer with the 1.7 Glass Path Corrector and I use it on my C6 pretty often. It's killer on the moon and planets. Very well made. Gives up a little light loss but I really love it. Alpine astro sells them for $389 with one Glass Path Corrector. You might want to consider one of them.

Hi Rodger,

what is the diagonal and visual back you use with the maxbright on the C6?

I use a Televue SCT Adapter short with a Televue 2 in. to 1 1/4 in. adapter and a standard Televue 1 1/4 in. Everbrite diagonal.

Hi Mike,

I used my Denkmeiers on a C6 sometimes and it seems to enhance whatever your looking at, compared to a single eyepiece.
The C6's have excellent optics. I was using my Binoviewer with a 1.25" Everbrite and using 3 different sets of Orion HighLight Plossl 1.25" Telescope Eyepieces, the 40mm, 32mm and 25mm.
Planetary observing with binoviewers is a real bonus because the extra contras you get with both eyes is really going to improve your views compared to any single eyepiece, regardless of the eyepiece quality.
Whatever you get is going to work fine. The william optics, is a fine binoviewer and any slight vignetting isn't going to mater with the planets or the moon because on planets, your going to keep the planet centered anyways, and the moon is so bright you still could need some type of neutral density filter to tone down the light.
Also, dont be too concerned about not having "premium" eyepieces. Everything coming out of china is pretty good these days, and people are more price savy now than ever, and optical quality has really taken a step upwards. Look at your scope, its Chinese made and is excellent optically.
I also have some 32 TV plossls and 24 panoptics Ive used with my binoviewer and these low cost Orion highlighters are every bit as good as my TV Plossls and the 24 Pans offer more field of view, but the optical quality isn't any better than my Panoptics.
Don't get too hung up on the technical issues of eye relief, field stop, and vignetting with your C6 and the gear you cant afford. Just go for the William Optics and enjoy the views.
Too many out here spend too much time nit picking the smallest details, and that can spoil an otherwise fine time your going to have with your gear. Don't let it happen.
The only issue Ive had with binoviewing my C6, is the binoviewer puts added weight on the back of the scope, so I found myself purchasing a longer dovetail so i can mount my scope further back on the longer dovetail so it will balance properly.
Spend more time learning the sky and less time worrying about your fine gear, and what you cant afford. There's allot more to observe than just the moon and a few planets with your excellent C6.
Get out of these equipment forums and spend more time in the observing forums, then you'll really start to appreciate what you can see with your scope, not what you cant do with your scope and gear.

...Ralph

Hi Ralph,

appreciate those comments. Actually, i sat back and thought things over. As it happens i have located a Baader 60 degree binoviewer. I'm waiting to send the payment for it. This bino will sort all the issues already discussed. I have decided i will cope with the 60 degree viewing angle. My friend used one one of these. The optics are very high quality indeed, but their small aperture input make them good mainly for planetary and lunar, which is just what i observe. Just hunting a pair of suitable eyepieces now. I will report on how it all performs when i have eyepieces and do a 1st light.

Mike

I tried my new WO binos with my C5 and loved the relaxed viewing of Jupiter. I'm now going to pick up some more paired eyepieces as the supplied 20mm are a little to low in terms of mag.

Hi Mark, Edggie,

I still have the original c6 1.25 v/back. I am very uneasy that it will hold the weight of even a typical WO or similar bino well. It is difficult to get at the two locking screws with enough pressure to really get a purchase on the diagonal well. I could certainly obtain something like a WO 1.25 diagonal though.
A much better grip would ben if i used my existing 2" v/back into which i insert a 2 to 1.25" self centring adapter, eg by revelation or orion. this would grip the 1.25" diagonal nosepiece well, but the combined length of the 2" v/b and self centre adapter would be around 60mm.
most WO etc are about 110mm light path. i think this would still bring a total light path over 200mm with a 1.25" diagonal. i am still concerned if i am operating at an undesirable f-ratio using the WO 1.6x. that then brings in issues about eyepieces to use. a friend has a pair of meade 5000 14mm plossls. i used these in the past and they were superb. will they offer a sensible mag in this potential setup? i do not know, as i do not know the operating focal length.

btw, i am actually looking at the original celestron 1.25 v/back, and to me it still looks to be around 50mm long to where a 1.25 diagonal would insert.
so, say 50mm v/b + 75mm for 1.25 diagonal + 110 for bino less 30 for 1.6x = 205mm. am i right? but still do not like the idea of all the weight on 2 little thumbscrews on that v/back!

You might find nylon screws (home depot) tighten better as they can squeeze against the barrel of the ocular or binoviewer.

Very well said there Ralph! Besides the 20mm that come with it, I use a pair of 26mm SP in them.

Yes, this is a good option and this is what I finally settled on for my C5 and EdgeHD 8"

I am still loosing a bit of aperture in the EdgeHD 8 even with this short configuration (about 7.6") but when I went to the Baader 15mm SCT to T2 adapter, I only got 7.7", and it was difficult to keep the diagonal from rotating because the Baader SCT/T2 adapter is simply not strong enough to hold the bino against rotation. It couples the way the old SCT diagonals do, with a lock ring, and if you get it tight enough to keep the diagonal from breaking free, it is hard to loosen it.

So, now I use the short Televue Short adapter and this works quite well. Neither the C5 or the EdgeHD 8" is working at full aperture, but I don't really use these for planets so much (though I use the C5 for the sun and moon) so it is a compromise that I don't like, but the utility makes it a better compromise than the Baader SCT/T2 15mm adapter.
