Filters 6 colors, 1 each (each filter is equipped with a separate plastic packaging box)
The specifications of the six commonly used color filters are:
12#, 21#, 23A#, 56#, 82A#, MOON&SKYLOW
12# yellow:
It is used to observe the polar ice caps on Mars more clearly.
When observing the desert land on the surface of the planet, the contrast can be increased to make the details more obvious.
When observing Jupiter, the blue color pattern of Jupiter's equator is darkened and the red and orange features are more detailed.
21# orange:
It is used to improve the contrast of light and dark when observing space, can penetrate clouds, observe Martian sand and dust storms,
and can be used to observe Jupiter's Great Red Spot. The effect is very good.
23#Red:
It is used to observe Mercury and Venus.
The sidebands of Jupiter can be observed more clearly through the red film with a large-aperture telescope, and more details can be seen when observing the surface of Saturn.
56# green:
Observe the polar projections, frost spots, and surface fog on the surface of Mars.
It is a good accessory for observing the rings of Saturn and Jupiter belt, and it is also a universal piece for observing the moon.
82# blue:
Used to observe the small structure of star clusters to make the image details clearer.
MOON&SKYGLOW:
It can penetrate the vapor layer, penetrate the ionosphere, and can be observed deeper and farther in the polluted sky.
Especially when observing star clusters, it can reduce the influence of stray light and search for strange new stars.
VLT means visible light transmittance
High-pass filter---
mainly to pass the band above the specified wavelength and filter out the specified wavelength
the following bands;
Low-pass filter---
mainly to pass the band below the specified wavelength and filter out the specified wavelength
above bands;
Bandpass filter---
mainly to pass the designated waveband and filter out the unnecessary waveband;
12#---74%VLT,
21#---46%VLT,
23A#---25%VLT,
56#---53%VLT,
82A#---73%VLT
MOON & SKYGLOW FILTER is used to observe the galaxy clusters through the ionosphere.
