TS-Optics Photoline 80 mm f/6.25 FPL53 Apo - Carbon Tube - RAP Focuser

TS Photoline 80 mm FPL53 Apo with Carbon Tube

Compared to similar telescopes with the same aperture, the apo offers several advantages that make the refractor attractive for astrophotographers and observers. In addition to the high-quality workmanship due to the production in Taiwan, the refractor offers above all:

Faster cooling than with a triplet objective, with comparable chromatic correction to an FPL53 triplet through the use of 2 special glasses.

Better focus stability and less weight due to the carbon tube - 3.5 kg

Flexible universal base, suitable for photo tripods, but also for various dovetail bars

Very good photo correctors for astrophotography are available.

360° rotation for selecting the correct image section is built in

The retractable dew shield reduces the transport length to only 38 cm.

120 mm working distance from the 2" receptacle allows the use of 2" accessories for observation and many correctors and focal reducers for astrophotography.

The stable, ball-bearing mounted 2.5" focuser:

The focuser is designed to support high loads and will also impress demanding photographers and, of course, observers. The drawtube is mounted on ball bearings. The adjustment is decoupled and takes place via an extra wide rack and pinion. This allows sensitive adjustment even with heavy accessories. Motorized focus systems such as the EAF from ZWO can be used without additional adapters. In addition to the 2" and 1.25" adaption, the focuser also offers an M54x0.75 female thread for the screw connection of correctors for astrophotographic use.

Suitable correctors for astrophotography:

WiflatT2 and WiflatM48 - 1.0x image field correctors: The focal length is not changed. The corrector is simply clamped over the 2" receptacle. The working distance from the T2 or M48 thread is 55 mm. The WiflatM48 is even designed for sensors up to full frame format.

WiRed08 and WiRed06 - image field correction and focal length reduction: The focal length is reduced with simultaneous correction of the image field. We recommend the correctors for sensors up to APS-C format. The working distance from the T2 thread is 55 mm.

TSFLAT2 - the individual corrector for screw adaptations: The female M54 thread also allows the TSFLAT2 1.0x field corrector to be adapted. With this adaptation, the corrector is permanently threaded to the focuser. A T2 bottleneck is avoided. The corrector is placed in the drawtube and screwed to the internal M54 thread of the focuser via an individual connection adapter. The working distance from the M48 thread of the corrector is 120 mm.
