APO 115 Refractor Astro Professional 3 lenses

Guaranteed Quality plus, learn more

Our Professional Series offers telescope tubes which meet the highest requirements. Only tubes that meet our extraordinary standards regarding optical and mechanical quality are used. The ED telescopes for example captivate through their chroma and excellent contrast. The achromatic refractors are equipped with particularly high-quality lens-systems that are not comparable to “normal” Fraunhofers. All focusers used in this series are suitable for astrofotography. This series was knowingly build in a modular way, so the customer can custom-build his telescope out of our components. If you have any questions about compiling the parts our team is there for you to help!

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.

Our Optics-Guarantee:
Every single Astro-Professional 115mm APO is completely checked by us and delivered with a Interferometer-certificate. This is our way to assure that we only deliver optics that meet our quality standards.

Highly precise working 2” 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.

Here you can see the red dot finderscope on a metal holder. The finderscope is adjustable in both brightness and the size of the red dot so you can always orientate yourself at the sky.
One can attach the finderscope either to the tube ring or the focuser.
The quick coupler gives the user the possibility to attach and detach the finderscope without any tools, so the telescope and the finderscope can be stowed in the transport case quickly.

The ED 110 is equipped with a first class coated ED optics featuring a blackened inner tube with a screen system for highest possible optical quality. The dew cap is retractable so the telescope is even more compact and easier to transport.
