Quark Chromosphere - no image at all

Post by JochenM »

Hi

I received a Quark Chromosphere today and have been spending the last two hours trying to get it to work. But not matter what I do, I can't get it to show an image at all (both through camera and eyepiece). I'm sure I'm centered on the sun, if I look through my LS50 on the other side (dual mount) I can see everything just fine.

I've been trying with both a smaller (80mm f7) and larger (150mm f8) setup, using a 35nm sub aperture ERF and without, diagonal or straight through, everything results in just looking at a black canvas. The light on the Quark is green and whatever position the knob is in also makes no difference.

Is my Quark just busted or am I missing something extremely obvious (yes, I removed the front cap :D)?

Any insights are highly appreciated.

You removed the other cap too?

There's only two caps to remove right (one on the nose and one for the eyepiece)?

Yup, just 2. You definitely centred on the sun? Take quark out and see if the diagonal has light outputting.

Hi Jochen,

looks a familiar experience first time Quark use. Wel if on a dual mount one scope point to the object, does not necessaraly mean the second one also does. (Cone error between the scopes). With the Quark the fov is very small, and also I had troubles finding the Sun first time. Also Quark has a 4x telecentric so there is focus shift.

What I did was remove the eyepiece and move the scope, and look into the eyepiece holder from a distance. It will get lighter and redder when near to the Sun. A certain moment you should see that the Sun moves in fov.

And yes the caps are important. I almost melted one.

Thanks for quick feedback guys. Really appreciate it.

The problem is with my diagonal it seems. I swapped out my Baader diagonal for a cheap/simple Skywatcher one I have lying around and that seems to fix the issue. Will figure out why that is later.

Happily testing out the Quark as we speak. Thanks again.

Herschel? Quarks don't work with those

No, just a "normal" Baader Clicklock diagonal. Something had fallen into the diagonal, obstructing the light path. Took that out (very lucky it didn't melt), problem solved.
