Refracting telescopes

The TS 102 mm f11 SDP Apo offers excellent chromatic aberration correction by pairing FPL53 with additional special glass

• Very good correction of chromatic aberrations by a 2-element APO lens with FPL53 from Ohara and an additional special glass
• Very good correction also in the violet color range, where faster SD-Apos give in a bit
• Even at 250-300x sharpness is maintained
• Adjustable lens mount
• Improved 2.5" rack and pinion RAP focuser with photo thread, 2" and 1.25" adaption
• Retractable dew shield for better transport and optimal protection against stray light
• Deluxe finder holder for adapting finder telescopes
• Binoviewers can be used without path compensation
• CNC tube rings and EQ5 style dovetail bar included
• With only 4.6 kg the ED is well supported by mounts like the Skywatcher EQ5
• Each TS Apo is individually tested before shipping (optics, mechanics, cosmetics), a checklist is attached.

An ultimate and compact APO refractor for astrophotography and observation.

• Aperture 110 mm / focal length 528 mm / focal ratio f/4.8
• FCD100 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
• Each apo is tested (cosmetics, optics and mechanics) at Teleskop-Service before shipment, the optics are collimated. The apo is shipped with a checklist.

The fast 110 mm ED APO offers good chromatic correction through two special glasses, it is designed for observation and astrophotography.

• Aperture 110 mm / focal length 660 mm / focal ratio f/6
• 2-element APO objective with FPL51 and Lanthanum glass from Ohara-Optics
