Daystar Quark Calcium H-line

Description

Visit Quark Calcium H-line takes the practical, all-in-one concept of the original Quark, but optimized for the stingray Calcium H (397 nm).

Designed for F/7 or moreIt allows both amateur and advanced astronomers to easily explore solar activity in Calcium.

Why choose Calcium H?

Stingrays Calcium H and Calcium K offer almost identical views of the solar surface.
However, many older astronomers do not perceive the K spectrum (393 nm) well. This is why the H-line (397 nm) is recommended for visual observation:
the longer wavelength makes it accessible to a larger number of observers.

With this filter, you can see :

  • active regions and shiny beaches,
  • faculae and structures close to sunspots,
  • the chromospheric network in contrast.

Key features

Features Detail
Wavelength Calcium H - 397 nm
Bandwidth (FWHM) ≈ 5 Å (variable according to instrument)
Compatible refractors F/7 or higher (shorter possible with Powermate 2x-2.5x)
Design All-in-one, lightweight eyepiece format
Power supply USB, 5V 1.5A, low power consumption (optional portable battery)
Compatible ERF filters No red or yellow glass. Recommended: UV/IR cut filter
Optical treatment AR coatings optimized for 397 nm, internal baffling

Safety and recommendations

  • A energy rejection filter (ERF) adapted to the telescope is required for safe use.
  • The Calcium Quark cannot be used with a front-mounted ERF of the instrument.
  • The use of a UV/IR cut filter is strongly recommended to protect the optics and the observer.

Summary

Visit Daystar Quark Calcium H-line makes solar observation in Calcium accessible, simple and affordable,
with sufficient brightness for most observers and excellent compatibility with standard refractors.
It's an ideal educational and scientific tool for exploring chromospheric phenomena.

* The Quark is a product of DayStar Instruments, using Fabry-Pérot etalon technology.
