Daystar QUARK Magnesum I b2 line filter

MODEL Daystar Instruments Magnesium I b2 line version of the Quark

Daystar Instruments QUARK is the first Magnesium "Eyepiece"

Attach it to your refractor and turn it into a solar telescope

For use on refractors from F4 to F8 and up to 80mm aperture for short, non-tracking sessions.

From 80mm you will need an ERF Filter (Energy Rejection Filter) to use with tracking.

Recommended to always use the daystar UV/IR filter (article 63518) and mandatory from 150mm aperture

Magnesium shows a high contrast between the granulation and the limit of the spicule in addition to the emission of the pest

Magnesium, a bright green color, is easily visible at the center of the highest sensitivity of the human eye. Studies of the Mg line are related to the boundary layers between the granulation and the spicule. In addition to strong surface mottling and high-contrast graininess, the Mg line also shows the plague in equal or greater detail than the Calcium line. Magnesium wavelength studies will reveal Zeeman splitting in the absorption of magnetized areas of active regions.

~ Magnesium filter I b2 Specifications: CWL: 5172.8 Å / FWHM: <0.5 Å ~

For use with refractors from F/4 to F/8 and up to 80mm aperture for short, non-tracking sessions, the user does not need to worry about settings.

From 80mm, the use of ERF (Energy Rejection Filter) is mandatory and thus it is already suitable for observation sessions with follow-up.

The Magnesium filter is not compatible with red and yellow energy rejection filters, so it can be used with refractors up to 80mm in diameter (according to our products for sale) and using Daystar's UV/IR filter (Number 63518). short sessions without follow-up.

Below 80mm, the use of ERF (Energy Rejection Filter) is recommended for sessions with monitoring, in addition to significantly improving its performance.

Just insert it into your diagonal, add an eyepiece, and see.

The QUARK contains a custom Daystar Instruments 4.2X telecentric Barlow lens fully optimized in coatings and optical design

This highly specialized 4.2x telecentric lens offers superior field uniformity and allows you to achieve the device's ideal working focal length between F15 and F30.

No specific FWHM bandpass is designated, however the etalon will be about 0.3-0.5 angstroms

Observers can now choose to purchase a filter based on their observing goals rather than their budget.

Fully optimized design eliminates the need for adapters.

Everything is combined in a lightweight device the size of an eyepiece.

The new compact design configuration eliminates unnecessary components, weight and associated costs. We've even reduced power consumption, so Quark can now run all day on an optional small, palm-sized battery.

*The QUARK array is a product of DayStar Instruments, utilizing DayStar Filters' Fabry Perot etalon technology.

1.25" or 2.0" combination eyepieces with safety notch slot directly on its diagonal

Standard 1.25 eyepiece drawtube output with optional 2" and SCT accessories available

Brass compression ring to protect the eyepiece.

Uses USB power, 5v 1.5amp Includes 90-240VAC wall adapter with international plug adapters.

Adjustment knob allows wing change +/- 0.5Å with detents at every 0.1Å.

LED indicator for power, warm-up, ready and fault

5 year warranty.

Optional 8 hour battery pack available.

Integrated 2-element 4.2X Telecentric Barlow

Integrated 12mm blocking filter 21mm clear filter opening

Best performance with F/4 - F/8 refractors

Full viewing of the Solar disk possible on refractors up to ~450mm native focal length

No opening limitations. Can be used on larger refractors for higher magnification views combined with the energy rejection filters.

Supplied in a convenient swivel case for safe, dust-free storage.

Not for use in retro-reflectors or reflectors or with off-axis energy-rejection ERF filters, or Red or Yellow Energy-rejection ERF filters.
