How do H alpha filters work?
H-alpha filters work by rejecting all but the narrow sliver of H-alpha light. The narrower the filter wavelength, the more off-band light is eliminated and the greater the contrast, all crucial factors for seeing details in the chromosphere.
What is a Daystar quark?
DayStar QUARK is the first Hydrogen Alpha “Eyepiece”! QUARK’s fully integrated design reduces exess weight, reduces costs, saves power and increases contrast. This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar hydrogen alpha filter into one simple assembly.
How does a Daystar quark work?
Daystar produces two Quarks; one for prominences (bandpass 0.8-0.6Å) and one for the chromosphere (0.5-0.3Å). The host refractor needs a focal ratio between f/4 and f/9. The Quark design incorporates an hydrogen-alpha optimised 4.3x telecentric Barlow, giving a magnification 4.3x higher than prime focus.
Can you see solar flares with a telescope?
To see flares and prominences, you need a much more specialized filter which only passes hydrogen alpha light. These can be used in front of refractors, but most observers prefer a dedicated solar telescope like the Coronado PST (Personal Solar Telescope).
What is H-alpha light?
H-alpha light is the brightest hydrogen line in the visible spectral range. It is important to astronomers as it is emitted by many emission nebulae and can be used to observe features in the Sun’s atmosphere, including solar prominences and the chromosphere.
What is a solar telescope used for?
A solar telescope is a special purpose telescope used to observe the Sun. Solar telescopes usually detect light with wavelengths in, or not far outside, the visible spectrum.
Where are Lunt telescopes made?
the USA
Lunt Solar Telescopes are built in the USA for those that desire to take in the full beauty of the sun.
How many stops is a solar filter?
Solar filters can range from 16-stops to 24-stops.
Can you make your own solar filter?
It is relatively easy to make your own filter with some poster-board material, filter sheets, and a little glue and tape. In a pinch, you can even cut out a piece of filter material and connect it to a lens with a rubber band. With filter in hand, you are ready to make your own images and see the sun in white light.
Should you look directly at the Sun?
REMEMBER: Looking directly at the sun, even when it is partially covered by the moon, can cause serious eye damage or blindness. NEVER look at a partial solar eclipse without proper eye protection.
Can you look at the Sun with a solar filter?
Imaging the Sun in white light With a dedicated solar filter over the front of your telescope, results can be captured and viewed instantly by holding a camera phone or compact camera afocal to the eyepiece, with a DSLR camera at prime focus or even by projecting the image of the Sun onto a white screen.
