The DayStar Combo Quark 2.8× Telecentric Barlow is the matching optic for DayStar's Combo Quark solar filters. A telecentric Barlow does more than magnify: it delivers light to the filter in parallel rays, which is exactly what an H-alpha filter needs to perform correctly across the whole field. This 2.8× version is the lower-power option for wider solar views.

If you run a Combo Quark — the version without a built-in Barlow — a telecentric like this is a required part of the imaging or viewing train.

Who it's for: Solar observers and imagers running a DayStar Combo Quark who need a telecentric to complete the system. New to imaging optics? Start with our guide to astrophotography for beginners.

  • Telecentric design: Delivers parallel light to the Quark filter for correct H-alpha performance across the field.
  • 2.8× magnification: The lower-power option for wider solar framing.
  • Made for Combo Quark: Pairs with Combo Quark filters that lack a built-in Barlow.
  • Imaging-friendly: A common choice for wider-field solar photography.

Why does a Quark need a telecentric Barlow?
H-alpha filters work best with parallel light. A telecentric supplies that across the whole field, unlike a standard Barlow.

Should I choose 2.8× or 4.3×?
The 2.8× gives a wider field for full-disk views; the 4.3× gives higher magnification for close-up detail.

Do I need this with a standard Quark?
No — standard Quark eyepiece filters already include a built-in telecentric Barlow. This is for the Combo versions.
