Astronomik H-beta Filter, Astronomik H-Beta 12 nm Visual Filter - 2" - HB-2, Astronomik H-beta Filter - gerdneumann.net, Astronomik H-beta Filter | First Light Optics, Astronomik 2" H-beta Filter - Telescope experts Astroshop, Astronomik H-Beta Filters - Rother Valley Optics Ltd, , , .
The optimal aperture ratio for the use of the filter is 1:4,5 to 1:6. The range of application extends from 1:3.5 to 1:15. Transmission losses and chromatic distortions, which arise with other filters, are only apparent with the Astronomik filters when extremely fast aperture ratios of 1:3 and higher are used. The Astronomik H-beta filter will allow you to view large objects, in the whole field of view of the eyepiece, even when using wide-angle eyepieces - not only in the center of the eyepiece. This filter should be used on telescopes with a diameter of 8 " (20cm) or larger. Smaller instruments do not gather enough light for meaningful and satisfying astronomical work. Due to the high optical quality of the Astronomik H-beta filter substrate you will see the same needle-sharp stars as you would from your regular telescope.. Click the image for full resolution. The Astronomik H-beta is a filter for visual observation, in particular with instruments of larger aperture.. Astronomik H-Beta Visual Filter - 2" 2" threaded cell mounted round filter for visual purposes Allows light from H-Beta emissions to pass while obstructing nearly the entire remainder of the spectru.

The Astronomik H-beta is a filter for visual observation, in particular with instruments of larger aperture. It lets the light of the H-beta emission line pass nearly unhindered and blocks the remaining spectral range to the extent that the eye is dark adapted.. Astronomik H-beta-CCD 12nm Filter. The Astronomik H-beta filter is a narrow band emission-line filter for CCD photography. The filter lets the H-beta light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive..
