Hi!

Got a bino viewer like this
https://www.astrosho...oviewer/p,59336

I tried it with 25mm plössls and my quark today but could hardly see anything but reflections of my own eye and the surroundings. If I used a towel to block light, I could see something but there were still many reflections and a lot of "haze". Cute eye much much better without the bino.

Are binos no good for a quark or are there some special requirements for it to work?

This is the first time for me with a bino, so I may just be a rookie :-)

Best regards
Søren

Describe your telescope, please

[UniversalMaster]

152 mm f5 refractor stopped down to f7.5, 2" dielectric mirror, Baader 5nm halpha and uvir for rejection, quark, eyepiece or bino.

Binoviewers are great with the quark. ( At least mine). You might want to look into some sort of eye shade to block stray light. Bino bandits or DIY, see below.

Also, the output from the quark is polarized and a minority of binoviewer designs do not play well with this. I think that is unlikely to be your problem though.

What a great idea, thanks :-)

I love my Quark with Binoviewers.

 

My setup is this:

Astronomics 102mm ED f/7 refractor.

William Optics Binoviewer, with matched 32mm and 25mm Plossl eyepieces.

Quark Chromosphere. 

Daystar UV/IR cut filter. 

 

 

You may give this setup a SERIOUS consideration.

I have been observing the Sun visually for over 20 years and THIS setup, IMHO, will rock your boat! 

 

Just maybe it's worth a shot trying this. You already have the Quark. IMHO, I think your setup introduces multiple variables that will not make the Quark perform to its best, ESPECIALLY your Binoviewers.

 

Even if you were START with changing your Binoviewer to the William Optics, and if it fixes your issue, it would only cost you around $300 or so. 

 

The more I think of it, the Binoviewer and/or the eyepieces are your problem.

Astro Tech ED72 refractor

Two 50mm extension tubes

Quark Chromosphere with Player One S-Series filter on its nose

2" to 1.25" adapter

Williams Optics Binoviewer with its 1.6X Barlow removed

25 or 32mm TeleVue Eyepieces 

 

Works like a charm with fabulous viewing.  

 

Are you sure you are at focus when trying the Binos?  

[UniversalMaster]

Yes I'm at focus. The problem is crazy high reflections from the surroundings and haze when using the bino. Also they eye placement has to be very precise to see anything, so it is very difficult to view. View is much much better without them bino.

Maybe this type of bino is no good for the quark?

The views without the bino are very good, so no need to change to much else here. Maybe the uvir or halpha filter could be too blame?

Crazy reflections come from either your eyepieces or the binoviewer.

You might have my problem wherein my eyes can’t accommodate the polarization in prism based binoviewers in Ha. I tried everything from cheap binos to Maxbright II Denkmeier and all I could ever get was wild reflections and blackouts. I finally called Russ at Denkmeier and we discussed everything that I had tried before when he told me that he had heard of people who had problems with the polarization from prism based binoviewers.

 

I ended up buying an Apo SS binoviewer from Denis Levatić and now I have no problems at all. For a lower cost option I also own one of the various linear binoviewers that are also mirror based and I can use it on Ha solar as well.

 

FWIW, I had no issues with binoviewers with anything other than Ha solar.

 

Just a thought. 

[UniversalMaster]

"wild reflections and blackouts" pretty much sums up my experience I do have one of the "cheap linear" binos, where the ad says

 

"Features a dielectric-coated beam-splitting mirror - not a prism - which reduces aberrations and improves contrast"

 

So I guess I may have a different problem?

I guess you do have a different issue. I would have bet money that the linear bino would work.

When you change over from a single in-focus eyepiece to the Binos, who much does your back focus change to bring your Binos to focus?
