new focuser for binoviewers?

[trent_julie]

Good evening all,

Just a quick call out for any forum members who have had success with William Optic binoviewers and a 16inch meade lightbridge.

I Have discovered that I need just a fraction more inward travel on my Lightbridge,

Now I have done plenty of reading about people who have come across this problem but very little about how to solve it.

I am prepared to buy a new low profile focuser such as a Moonlight or JMI to solve this issue, but before I head down the new focuser path I would at least like to hear one success story.

Cheers,

Trent

Barlowing would sort that out in the interim to reach focus.

Thats exactly what I thought! Unfortunately it didn't I tried the supplied nose piece and also a 2.5x powermate, with the barlow it seems I need about
3 - 5mm inwards travel,

It would be nice to use the binoviewer without a barlow of any kind, And I'm not a fan of moving the mirror forward to compensate.

Thanks for your response

Hi Trent.

Have you tried using the primary mirror collimation bolts
to move the whole mirror forward that 5mm or so?

The Stellarvue binoviewer that I have actually came with a couple of little tube tyoe things that are intended to be used if the scope won't come into focus normally. I find that I need both of them for me 12" LB. Maybe Peter at SDM sells these as an extra too. You could ask for nothing, and that would be a cheap way out.

Hey, the iews of the Moon, Jupiter and Saturn are incredible through a binoviewer. it's worth chasing up

Do these tubes have lenses? As I Believe I have an inwards focus problem

So I keep on hearing, I can't wait........ I'm looking forward to the bright DSO's

Success,

I purchased a purpose built corrector from Siebert optics, views where excellent, whilst we can't say that we were able to notice the ever famous 3d effects when looking at Saturn, we did however, notice some "popping out" of stars when observing the Jewel Box.

So in summary,
I found that the bino-viewer was more comfortable to observe through than a single eyepiece, and we succeeded bino-viewing with a 16inch lightbridge, all that was required was a 3rd party corrector.
