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

Antlia OAG and filter drawer assembly is an innovative accessory that integrates filter drawer and OAG.

• Large 12*12 mm pick-out prism for using a larger guiding sensor, therefore greater choice of guide stars.
• Mono-block (one-piece) design with the OAG body directly connected to the filter drawer - provides a very rigid platform for guiding.
• Comfortably fits APS-C sensor and full frame sensor.
• The total thickness plus both side adapters is 37.5 mm.
• Right for cameras with 17.5 mm back focus distance without additional adapters.
• A high-quality 1.25-inch helical focuser with a generous 10 mm of travel allows you will find the optimum focus for your guide star.
• The prism height can be adjusted to better illuminate the field of view of your auto guider. The smaller the imaging sensor in your camera the further down the prism can be set without interfering with the sensor.
• Dovetail-type threaded adapters are attached to the body with grub screws, so the adapters can be 360° rotated and locked to align with the telescope and camera.
• You can rotate the OAG 360° to find a guide star.
• Telescope-side connections (female thread): M48, M54, M68
• Camera side connections (male thread): T2 (M42x0.75), M48, M54, M68
• Connection adapters also fit to the respective other side
• Suitable for 2" filters
