... 4 element APO telescope with field correction for astro photography - 2" RP focuser - FPL53 glass

TS Quadruplet 65mm Superapo Astrograph
Picture shown with optional dovetail bar

The TS Quadruplet Astrograph 65mm f/6.5 of the TS Imaging Star Line offers a highly corrected focal plane for astro photography and is therefore an interesting alternative e.g. to the Takahashi FS-60 or the Pentax 75 SDHF. It is fine crafted and optimal for mobile deep-sky imaging featuring a minimum mechanical length of 340 mm (with retracted dew cap). Image quality on- and off axis is perfect and the very low chromatic abberation allows a visual magnification range up to 150x.

TS APO 65 Quadruplet advantages:
-- fully corrected triplet lens group for colour-free imaging
-- integrated field flattener (4th lens) for a corrected fiels up to full-size sensors
-- optimized flattener position inside the tube for best effect
-- 2" dual speed focuser for high loads - no slipping, no shifting
-- 360° rotation possibilitiy for ideal framing
-- CNC tube rings
-- finder shoe (Vixen/Celesstron/Skywatcher compatible)

2" Rack and Pinion focuser:

Rack and Pinion Focuser

This focuser combines the advantages of a rack & pinion focuser with an improved bearing system. A Crayford design has its optimal stiffness only when the drive shaft is pressed firmly against the rail - this causes bucky operation. The fine machined cograil allows smooth focusing even under heavy loads up to 3 kg.

The focuser also features a 2" and 1.25" receptacle with brass compression rings. 2" accessory is locked by two thumbscrews - this prevents tilting.

The 65mm Quadruplet's optical system - four lenses in two groups:

Optic of the 65mm Quadruplet Astrograph
For this lens system FPL-53 glass is used for optimal colour correction. Stars are free of colour fringes and halos which may occur with camera-side corrector applications.

The fixed internal ED flattener causes an optimal image correction for sensor with a diagonal up to 44 mm. With a separate lens brought into the focuser, this can hardly be reached. This highly corrected system is additionally supported by a adequate baffling system
