♦ Aperture 110 mm / focal length 528 mm / focal ratio f/4.8

♦ FDC100 triplet lens with f/6 - chromatic correction comparable to FPL53 triplet

♦ 4-element 0.8x corrector with M48 camera connection and working distance of 55 mm included - designed for this lens for highest field sharpness

♦ 2" filter thread and 360° rotation included

♦ 2" Visual-Back can be screwed to the focuser instead of the corrector for observation - working distance suitable for 1.25" and 2" accessories

♦ Delivery in high-quality carrying case

 

TS 110 mm f/4.8 Flatfield Apo for Astrophotography

This apochromat offers chromatically very well corrected optics and the best possible field correction. The objective is optimized for very good chromatic correction without compromise. The sphere is also exemplary. The Ronchi test reveals straight lines. Thus, the apo is designed for observation up to the highest magnification range of about 350x.

For astrophotography, a 0.8x full-frame corrector was developed especially for this objective. The 4-element corrector provides very good imaging quality throughout the field. Even with high-resolution full-frame sensors, such as ZWO´s ASI6200 camera, the stars will remain pinpoint at the edge.

The idea behind the TSAPO110FLAT:

Until now, you have always had to compromise with flatfield optics, sacrificing some sharpness on the axis in favor of good field sharpness. Or you take a "general corrector" and try to achieve the best possible field correction by adapting distances. The result is a compromise, usually a good one, but still a compromise.

The concept behind this apo avoids the compromise, because the 110 mm f/6 objective is optimized for highest sharpness on the axis. And the corrector is optimized only for this objective. Four elements were necessary to make the high sharpness available to you in the entire field.
