a long time the astro community has been waiting for an affordable
APO-Astrograph that can be used mobile; even with large camera sensors.
The TS 86SDQ is designed for deep-sky and widefield astrophotography
with all custom astrocameras. The very good correction enables the use
of high resolution cameras with small pixels as well as the use of
cameras with large sensors, exceeding full format.
weighs 4 kg whilst being very compact and can be operated on mobile
mounts. The TS 86SDQ is also suited for plane trips. These features make
the TS 86SDQ a high-quality and convenient telescope for outstanding
Even though the apo is optimized for
astrophotography, it can still be used for observing with 2" diagonals
thanks to its generous backfocus. The excellent color correction permits
magnification up to 200x without any chromatic aberration.
Features and advantages of the TS 86 mm SDQ Quadruplet Apo
♦ Field correction and illumination as far as D=60 mm
The 2-element correction system is integrated and independent of the
focuser. These correction elements are made from FDC-100 glas
(comparable to FPL-53)
♦ High Quality FDC-100 Doublet lens for an image without color defects in combination with the 2-element correction system.
♦ 3" CNC-Rack&Pinion-focuser - permits load up to 6 kg
♦ 1.25" and 2" plug-adaptation as well as a M82x1 thread for screw connection are available.
♦ Each Quadruplet Apo is checked before shipping and its optics are tested
Camera connection to the 86SDQ:The
APO provides a backfocus of 95 mm from the 2" connection. The focuser
tube can be extended by 40 mm. We recommend the following adaptations
(items are linked in the accessory section below).
♦ DSLR connection via 2" tube:
With the focal adaptor TSFA240 and a standard T2 ring you can attach and focus all DSLR cameras.
♦ Connection of DSLR and astrocameras with sensors up to 30 mm diameter via the M82 thread:
the adaptor FTSM82-M48 and the M48 reversing-ring M48a-M48a you get a
M48 connection at a backfocus of 102 mm. There is space enough for each
photo equipment like filter wheel, off-axis guider ... system cameras or
astro cameras need an additional extension if it isn´t included.
♦ Connection of DSLRs and astro cameras with large sensors exceeding 30 mm diameter via the M82 thread:
adaptor M82i-M68a provides a Zeiss-Level thread connection with a M68x1
male thread at 102 mm backfocus. Due to the M68x1 adaptation system by
TS-Optics and Baader you are able to attach your camera.
We will gladly help you with your individual adaptation, depending on what type of camera you want to use.
