TS Optics Apochromatic refractor AP 80/560 Photoline OTA

Item Description:

The new Photoline Apo from TS Optics offers very good performance in every area of ​​observation and astrophotography.

The image quality sets standards in this class. The "Extra-Low-Dispersion" glass FPL53 from Ohara, Japan, is used in the lens. This high-quality apochromatic element and the relaxed focal ratio of f / 7 allow an image that is practically free of chromatic aberration. The doublet lens also enables faster cooling.

The advantages and features at a glance:

• Ball-bearing focuser with rack & pinion (gear drive) adjustment. The storage is decoupled from the adjustment of the extension tube.

• Oversized pull-out tube with 60 mm free opening for full illumination even with full format.

• 1:10 micro-reduction for ultra-precise focusing

• High-quality CNC tube with inner panels and very good internal blackening - no annoying stray light

• M63x1 internal thread enables stable screwed adaptations for astrophotography

• The dew cap can be pushed in - the transport length is then only 46 centimeters

• Modern and multi-coated 2-element lens with FPL53 as APO element

• High-quality CNC clamps and GP-level prism rail with photo tripod connection
