TS Photoline 130mm f/7 Triplet Apo - FPL-53 - 2.5" RPA Focuser

We stands on uncompromising optical and mechanical quality with the PHOTOLINE APO series.

The 130 mm f/7 triplet refractor is equipped with one of the best lenses in its class. The apo element is the proven FPL53 from Ohara (Japan). The lens, free from chromatic aberration, is mounted in a temperature-compensated cell that also compensates for sub-zero temperatures. A solid metal tube and the new PHOTOLINE RAP 2.5" deluxe focuser with rack and pinion drive make this apochromat a recommendation for the dedicated astrophotographer and the observer.

Advantages and features of the PHOTOLINE 130-mm-F7-Apo:

• Triplet lens with air gap - apo element made of FPL53 by Ohara
• Temperature compensated, fully adjustable cell
• 2.5" RAP Photoline dual-speed rack and pinion focuser - carries accessories up to 5 kg
• Direct M68 and M63 thread connection for correctors and reducers
• Sturdy aluminium tube with internal baffles
• An extension piece with M95x1 threaded connection can be unscrewed, thus increasing the working distance from 123 mm to 213 mm.

The new PHOTOLINE RPA 2.5" deluxe focuser - in elegant WHITE:

The 2.5" RAP focuser is a good alternative to the well-known Starlight FeatherTouch FTF25 - with a quality that is very close to this focuser. The focuser holds camera-side accessories up to about 5 kg without causing tilting. The illumination of the focuser is sufficient for full-frame size sensors.

• Adjustment via rack and pinion - no friction - no yielding as with the Crayford focuser
• Self-centering eyepiece and accessory adapter for 2" and 1.25"

The lens of the PHOTOLINE 130 mm F7 apo:

For this telescope, we deliberately chose the high-quality FPL53 as the material for the Apo element in order to offer the best possible optical quality.

The multi-coated lens is stored in a temperature-compensated cell. The lens is not cemented, the lenses are separated by air gaps. The lens edges are blackened.

Recommended correctors for astrophotography:

TS 2.5" full frame size corrector and image field flattening - TSFLAT2.5
