Quick Overview

TS-Optics SDQ APO 86mm f/5.4 quadruplet apochromatic refractor is an ideal astrograph for deep-sky astrophotography with large sensors. Thanks to Modified Petzval Quadruplet design, 86 mm diameter and 464 mm focal length f/5,4 with integrated corrector, it offers a wonderful 60mm diameter illuminated and corrected image field allowing the use also of cameras with very large sensors. The lens shows no chromatic aberration across the entire field and this telescope offers long 120mm backfocus (allowing to add also of 2" diagonal for visual use) and high quality 3" Rack&Pinion focuser with micro reduction.

TS-Optics SDQ APO 86mm f/5.4 quadruplet apochromatic refractor - photography use:

The APO provides a backfocus of 120mm from the 2" connection. The focuser tube can be extended by 40mm. We recommend the following adapters:

- DSLR connection via 2" tube: with the adaptor TSFA240 and a standard T2 ring you can attach and focus all DSLR cameras.

- Connection of DSLR and astronomy cameras with sensors up to 30mm diagonal via the M82 thread: with the adapter FTSM82-M48 and the M48 reversing-ring M48a-M48a you get a M48 connection at a backfocus of 130mm. When using two M48 extension tubes (TSVF230) you reduce the backfocus to 70mm which allows for focusing with DSLRs. System cameras or Astro cameras need an additional extension if it isn´t included.

- Connection of DSLR and astronomy cameras with sensors larger than 30mm diagonal via the M82 thread: the adaptor M82i-M68a provides a M68 thread connection with a M68x1 male thread at 130mm backfocus.
