Daystar QUARK H-Alpha Eyepiece - Chromosphere Model

A Revolution in Affordable H-Alpha Observing


The QUARK from DayStar filters marries a high-tech telecentric 4.2x Barlow lens with an exceptionally high quality DayStar h-alpha filter. Combining the Barlow, filter, adapters and snouts into one highly compact and innovative design. This all-in-one design is simply dropped into a diagonal, add an eyepiece and you're ready to observe! Compatible with refractors with focal ratios between f/4 and f/8 and best used with eyepieces with focal lengths between 25mm and 40mm, the QUARK will allow most refractor owners to view the sun without any additional equipment purchases.

Because the exact filter bandpass will vary depending on the refractor it is paired with, the QUARK has been configured into two models. By offering the QUARK at a very reasonable price, Daystar has made your solar observing goals obtainable! By choosing the chromosphere model, the QUARK will highlight solar surface detail specifically. If it's solar flares and prominences you're after, the Prominence model is the one for you. Want it all? Get both!

    Questions & Answers

    Ask a Question
    • Do I need a whitelight fliter or a H-alpha filter on the objetive?

      No, The Quark H-Alpha eyepiece is designed to work on it own without the use of any additional filters.

    • Hi OPT, I have the Chromosphere version on order. I'll be using a Stellarvue 80mm refractor as the scope. It seems from reading different materials that 80mm is the cut-off size for needing the UV/IR filter - do you agree, or do I absolutely need it? Als

      Daystar recommends the UV filter on an 80mm scope if you have a tracking mount as it is concentrating all of the solar energy on the quark for a longer period of time than letting the image drift through. You will need to put the quark into your diagonal

    • Will this also work for the Epsilon 130D?

      Yes, This will work with the Epsilon 130.

    • Hello Can i using the daystar quark h-alpha chromosphere model on my Celestron SC 8 inch??

      The Daystar Quark is not compatible with an 8" SCT

    • At anytime or circumstance, can an energy rejection filter (ERF) and a UV/IR filter be used simultaneously with the DayStar Quark H-Alpha Chromosphere model? Just curious.

      You can certainly use both with the ERF at the front of the scope and the UV/IR filter right in front of the quark, but the ERF already blocks pretty much all of the UV and IR already so you may not need both if you have the ERF already.

    • Will the Quark H-alpha work with an Explore Scientific 152mm f5.6 Mak-Newt?

      Good afternoon and thanks for asking. That aperture is much too large for a Quark. They are best around a 4" diameter scope.

      That aperture is much too large for a Quark. They live best around 4" in diameter.

    • What would I need to connect the Quark to a telescope without a diagonal? Is the front end threaded so that a Precise Parts adapter could be ordered? Does the camera side have a threaded connection?

      The scope side has both 1.25" and 2" slip fit adapters, so you would need an extension tube like the SV-ET3 or SV-ET475 to replace the diagonal and get you to a straight-through orientation. the output on the camera side is 1.25", though a custom adapter
