APO 115 Refractor Astro Professional 3 lenses - Glass from O`Hara - Japan

Featuring a large 3” focus tube!
Outstanding sharpness and free of color errors!



The new flagship of the Astro-Professional Professional series. The APO 115 refractor features a first class optical system which is completely free of any color errors. Our measurement report shows this. With this optical tool we offer you a refractor that meets highest expectations. Until a couple of years ago it was completely impossible to buy a telescope like this at the price we offer it now. The lens-system is equipped with a 3 lens
air-gap-objective with screws to adjust it.

This optical system is not cemented

Featuring a new, large 3” focuser with 1:10 reduction and an optionally available 2” flattener, we can offer a custom solution for astro-photography.
A fully lightened field of view is guaranteed
The dew cap is retractable and can be fixed with a screw.

Sharp design: The high quality white paint features a glossy mother-of-perl shine and therefor gives this telescope an unique finish. The rings and caps in metallic-black give the right accents to the paint. The focuser has the Astro-Professional logo engraved and matches the whole design idea.

The big 3" Crayford Focuser:



Highly precise working 3” Crayford focuser with 1:10 reduction.
We choose this focuser because it is perfectly suitable for
astro-photography and has a very good overall quality.
Due to the 1:10 reduction the camera or eyepiece can be focused precisely. The focuser is equipped with a 1.25” reduction ring in order to make the use of 1.25” accessories possible. Since it is 360° turnable it perfectly adapts to its user. It is also equipped with a scale.

The Triplet Objektiv is adjustable:
