TS-Optics PHOTOLINE 130mm f/7 FPL-53 Triplet APO Refractor

Teleskop-Service relies on uncompromising optical and mechanical quality with the PHOTOLINE APO series.

The 130mm f/7 triplet refractor is equipped with one of the best lenses in its class. The proven FPL53 from Ohara (Japan) is used as the apo element. The colorless lens is stored in a temperature compensated mount that also compensates for sub-zero temperatures. A solid metal tube and the new PHOTOLINE RAP 2.5" deluxe focuser with rack and pinion adjustment make this apochromat a recommendation for dedicated astrophotographers and observers.

Advantages and characteristics of the PHOTOLINE 130 mm F7 Apo:

♦ Triple air gap lens: Apo element made with Ohara's FPL53

♦ Fully adjustable frame with temperature compensation

♦ 2.5" RAP Photoline rack and pinion focuser with micro reduction - accepts accessories up to 5 kg

♦ Direct threaded connection M68 and M63 for correctors and reducers

♦ Sturdy aluminum tube with inner panels

♦ An extension piece with M95x1 thread connection can be unscrewed, thus the working distance is extended from 123mm to 213mm.

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

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

♦ Adjustment via rack and pinion - no friction - no sag like with the Crayford focuser

♦ Self-centering eyepiece and accessory adapter for 2" and 1.25"

The lens of the PHOTOLINE 130mm F7 Apo:

We deliberately chose high quality FPL53 as the material for the apo element in this telescope to provide the best possible optical quality.

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