TS-Optics Doublet SD-Apo 150 f/8

Codice articolo: TSAPO150-37

The new TS Photoline 150 mm f/8 Apo convinces with its high optical performance, neat chromatic correction and very good mechanics - with large 3.7" focuser for astrophotography with large sensors

♦ Aperture 150 mm / focal length 1200 mm / focal ratio f/8

♦ Very good chromatic correction due to color-pure imaging by "Extra-Low-Dispersion" FPL53 APO element from Ohara (Japan) and lanthanum glass element

♦ Fast cooling due to the 2-element objective design

♦ With only 9.5 kg the telescope is still transportable and can be carried by mounts from EQ6 upwards

♦ 3.7" focuser with 360° rotation - rack and pinion - one of the best focusers in its class

♦ Multi-coated objective and inner baffles for optimal contrast

♦ M92x1 and M68x1 female threads are available for screw adaptions - illumination up to full frame format is given

♦ Working distance 130 mm from the 2" receptacle or 230 mm without extension between focuser and tube

♦ Slide-in dew shield, CNC tube rings, finder shoe, dovetail bar and carrying handle are included in the scope of delivery

♦ Suitable correctors and focal length reducers for astrophotography are available

♦ Each apo is checked and optimally adjusted on the optical bench at Teleskop-Service before shipment.

TS 150EDF 150/1200 mm FPL53 / Lanthanum Glass Doublet APO Refractor

The TS 150EDF is our largest ED doublet refractor. It has the same optical design as the successful Photoline 125 mm f/7.8 apo. The inexpensive yet powerful optical concept makes this dream telescope affordable for amateur astronomers. Whether you are interested in solar and planetary photography and observation, or astrophotography of nebulae, star clusters and galaxies, this telescope will give you a very good performance.

The doublet lens with SD glass, one lens of which is made of FPL53 and the other of special lanthanum glass, brings the maximum performance and chromatic correction previously known only from triplet lenses. Each apo is tested on our optical bench before shipment, so you always have optimal performance at your disposal.

The advantages and features of the Photoline 150 mm f/8 Apo:

♦ Well corrected, air-spaced doublet objective - special glasses FPL53 (from Ohara) and lanthanum glass
♦ Temperature compensated, fully adjustable metal cell
♦ 3.7" RAP Photoline rack-and-pinion dual-speed focuser carries accessories up to 7 kg.
♦ Direct M92x1 and M68x1 thread connection for correctors and reducers for astrophotography
♦ Working distance 130 mm from the 2" receptacle, so you can easily get in focus with common accessories
♦ If you unscrew the extension between focuser and tube, the working distance increases to 230 mm. This allows you to use binoviewers without glass path compensation.
♦ Sturdy aluminum tube with inner baffles
♦ CNC tube rings with Losmandy style dovetail bar
♦ Weight only 9 kg at a length of 1.1 metre - so the apo is still very transportable
♦ Each apo is tested and optimally collimated on the optical bench of Teleskop-Service before shipping, so you have an optimal telescope for your use right from the start.
♦ Upon request and for an additional charge, we will send along a photographic test documenting the clean stellar imaging of the apo. An image focal, extrafocal and intrafocal and a Ronchi image is included. The apo will then get a TS serial number.

An ultimate high-end 3.7" focuser:

The RAP focuser is designed for heavy camera photography and observation. The focuser holds camera-side accessories up to about 7 kg without causing tilting. The focuser´s illumination is also optimized for full-frame sensors.

♦ Rack and pinion drive - no friction - no yielding as with a Crayford focuser
♦ M68x1 and M92x1 threaded connection for further adaptations
♦ Self-centering eyepiece and accessory adapter for 2" and 1.25
♦ 360° rotation for optimal camera positioning is built in
♦ Dual speed for precise focusing is built-in
♦ Motorized focusing can be retrofitted

Recommended correctors for astrophotography:

TSFLAT3 - 1.0x Full Frame Format Corrector

♦ The focal length is not changed.
♦ The corrector fits directly to the focuser.

TS 0.79x PHOTOLINE focal reducer and corrector - TSRED379

♦ Focal length is reduced to 948 mm, focal ratio improves to f/6.32
♦ Recommended distance from the M48 connection thread of the corrector to the chip: 55 mm
♦ The corrector fits directly to the focuser
