TS-Optics Photoline 150 mm f/8 FPL53 Lanthan Dublet Apo - 2.5" Focuser

The large 6" f/8 ED APO refractor is suitable for observation and for astrophotography and convinces by a good chromatic correction

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

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

♦ Fast cooling due to the 2-element lens design

♦ With only 9 kg the telescope is still transportable and is carried by mounts from EQ6 on

♦ 2.5" focuser with 360° rotation, ball bearing and rack and pinion drive - one of the best in its class

♦ Multi-coated objective and internal baffled for optimal contrast

♦ M63x1 female thread for screw adaptations are available

♦ Working distance 130 mm from the 2" connection - 230 mm if you remove the extension between focuser and tube

♦ Sliding dew shield, CNC tube rings, finder shoe, dovetail bar and carrying handle are included

♦ Suitable correctors and focal reducers for astrophotography are available
 

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 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
♦ 2.5" dual-speed RAP Photoline rack and pinion focuser - holds accessories up to 5 kg
♦ Direct M63 threaded connection for correctors and reducers for astrophotography
♦ Working distance 130 mm from the 2" receptacle, so you can easily get into focus with common accessories - 230 mm without extension
♦ Sturdy aluminium tube with internal baffles
♦ CNC tube rings with Losmandy style dovetail bar
♦ Weight only 9 kg with a length of 1.1 meters - so the apo is still very portable
♦ Each apochromat is tested and optimally collimated on the optical bench by Teleskop-Service before shipping, so you have an optimal telescope for your application from the beginning.
 

An ultimate 2.5" focuser in the high-end range:

The 2.5" RAP focuser is designed for photography with heavy cameras and for observation. The focuser holds camera-side accessories up to about 5 kg without causing tilting. The illumination by the focuser is sufficient for full frame sensors.

♦ Adjustment via rack and pinion - no friction - no yielding as with a Crayford focuser
♦ M63x1 threaded connection for further adaptations
♦ self-centering eyepiece and accessory adapter for 2" and 1.25"
♦ 360° rotation for optimal positioning of the camera is built-in
♦ Dual-speed for accurate focusing is built in
♦ Motorized adjustment can be retrofitted


 

Recommended correctors for astrophotography:

TS 2.5" full format corrector and field flattener - TSFLAT2,5

♦ The focal length is not changed.
♦ Recommended distance from the M69 connection thread of the corrector to the chip: 87 mm
♦ The corrector fits right on the focuser



TS 0,79x PHOTOLINE focal reducer and corrector - TSRED379

♦ The focal length is reduced to 948 mm, the 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 right on the focuser
