With the TS ADC your images of moon and planets as well as your observations near the horizon become significantly sharper and more detailed.

• Corrects the color shift (Dispersion) of our atmosphere - less color fringing, more sharpness and detail
• Convenient operation with eyepiece attached - simply rotate the lever and notice how the sharpness of your view or camera image improves.
• The principle behind the ADC is simple - two prisms are shifted relatively to each other and thereby compensate the color shift of the atmosphere (see image)
• A ring scale allows for reproducable adjustments
• Simple adaptation on the telescope side and eyepiece side via 1.25" receptacle and T2 thread
• Ultraslim design - the TS ADC can even be attached to binoviewers - height without T2 connection parts only 29 mm from T2 to T2
• Usable among others for observation and photography of planets, the moon or double stars
