♦ Aperture 140 mm
♦ Focal length 910 mm
♦ Fast focal ratio f/6.5
♦ Air-spaced triplet objective - 2 ED elements provide an image free from chromatic aberration
♦ Solid 4" rack and pinion focuser with dual speed - ideal for astrophotography
♦ Intermediate threads for screwed adaptations, e.g. M68x1 female thread
♦ Retractable dew shield
♦ CNC tube rings, carrying handle and dovetail bar are included in the scope of delivery
♦ Carbon tube for easier transport and high stability
♦ Delivery in transport case
♦ Every apochromat is tested by the manufacturer and Teleskop-Service before shipment
♦ Each apo receives a serial number and is delivered with a photographical test certificate
The apo offers a generous working distance, so that you can work with the TSAPORED075 (0.74x reducer) and still get into focus.
If you want to adapt the TSFLAT25DEL (1.0x flattener), you need the following components.
♦ M68a-M63i - adapter to extend the M63 thread of the corrector to M68x1.
♦ 2x TSVM6815 30 mm M68x1 extension - to get into focus without problems. The extensions are positioned between the M68x1 thread on the focuser and the adapter.
