120mm (4.75”) f/900 ED Apochromatic Refractor Telescope

• 120 mm aperture, 900 mm focal length, focal ratio f/7.5
• High image quality thanks to extra-low dispersion glass FPL53 (Ohara, Japan) and matching glass from Schott
• Highly effective coating for maximum transmission and minimum reflections
• Large Crayford focuser with 11:1 reduction for sensitive focusing
• 360° rotation adapter
• Tube in traditional white - heats up less during the day and is more visible at night

Fast 70mm high-performance astrograph F5.5 for demanding astrophotographers and observers with 5 lens elements in 5 groups

• Very fast 70mm high-performance astrograph for demanding astrophotographers
• Due to the large lenses there is almost no vignetting
• Complex construction with 5 lens elements in 5 groups for absolute correction
• Needle-thin stars up to the edge of the image field even with 44 x 33 mm camera format
• Large, stable eyepiece extension, also suitable for heavy cameras
• Extremely high sharpness, colour purity and contrast thanks to SD lenses
• Very large field illumination up to 55mm
• High Strehl intensity of 96.7% at visible wavelengths
• Optional reducer available for even faster results
• Optional motor focuser with two speeds can be retrofitted

The Askar 120APO is a 120 mm aperture, 840 mm focal length, and f/7 native focal ratio apo refractor with many useful features and two corrector options.

• Aperture 120 mm - focal length 840 mm - focal ratio f/7
• Triplet objective with one ED element
• Stable 3.3" RAP focuser with dual speed, 360° rotation and 100 mm travel
• Sufficient working distance for observing with 2" accessories and for photography
• Flattener and reducer (0.8x) available
• CNC tube rings with Vixen GP style dovetail bar and carrying handle
• Two finder shoes
• With optical test by Teleskop-Service on the optical bench (autocollimation) - star test extrafocal, intrafocal and focal as well as Ronchi test and report - so you have a 100% tested telescope

The powerful ED apo is suitable for observing and astrophotography with an high-contrast image.

• 150 mm aperture, 1200 mm focal length, focal ratio f/8
• High image quality thanks to extra-low dispersion glass FPL53 (Ohara, Japan) and matching glass from Schott
• Highly effective coating for maximum transmission and minimum reflections
• Large rack and pinion focuser with 11:1 reduction for sensitive focusing
• 360° rotation adapter
• Tube in traditional white - heats up less during the day and is more visible at night

Features

• Petzval-APO design: 4 groups, 6 elements with Dual-ED glass for minimal chromatic aberration and improved star performance.
• Integrated field flattener: Supports a 44 mm image circle – no additional accessories required.
• Fast maximum aperture of f/4.5: Improved light-gathering capability for shorter exposure times and more efficient shooting.
• 360 mm focal length: Optimised for large celestial objects such as galaxies and nebulae.
• Full-frame compatibility: Works with full-frame and APS-C cameras, as well as EAF focusing systems, filters and guiding accessories. What’s in the box

Takahashi offers rotating camera mounts for its telescopes, which are necessary because most of the company's focusers are not rotatable. However, this rotator also makes sense visually, as it allows the ZSP or other accessories to be conveniently rotated into the desired position. The quality is so high that there is no play even when the screw is loosened.

• Connection on the telescope side: M56x0.75 internal thread
• Connection on the camera side: M56x0.75 external thread
• Light path: 12.3 mm
• Weight: 110 g
