ADC unit is special corrector designed for planetary observers and photographers; observe planets not only high in sky but even rise and set; with high brilliance and colour and without chromatic aberration; make more flexible in choice of observing time
Prisms can be moved by 2.5 degree by means of two small levers and set a low or very high colour deflection; result is an even better correction of dispersion especially on horizon; rotatable ring scale quickly find optimal setting for next observing
Ultra-low profile - also suitable for visual observing and bino-viewers; ring scale for adjusting dispersion correction;Corrects atmospheric dispersion - less colour fringing; sharper planetary photos and more detail
The Astromania LRGB Filter Set includes four filters; 1.25" luminance Filter; 1.25" Red Filter; 1.25" Green Filter 1.26" Blue Filter; this LRGB filter set allows you to use your monochrome CCD camera to put together high resolution colour images
The LRGB set features dichroic glass filters designed for maximum transmission; the color filters have an IR-blocking coating; and all filters are parfocal to eliminate the need for refocusing between exposure sets
