 The high-tech 5 series!

As a fully configurable top-line device, we offer the SuperED Triplet Apo 123 / 738mm also with Star Light Instruments FeatherTouch Focuser 3.5? at. The massive and stable tube is made of aluminum to guarantee maximum stability.

If the conditions are right, weak fog structures (cirrus, for example) can be seen visually. These optics already collect 50% more light than a 4-inch device. We decided on a short system with f / 6 in order to give the astrophotographer a powerful tool. Both highly corrected f / 4.5 photo systems and? Planet killer? with f / 9 to f / 12 can be realized without any problems.

There? Fast? Openings require maximum focus precision, especially in photography, do we have the large 3.5? FeatherTouch extension with 360 ° rotation and 1:10 micro reduction installed. It guarantees freedom from vignetting and can be effectively equipped with all possible accessories. The massive construction allows the use of heavy additional equipment.

If you need a shorter or longer back focus, you can specify this when planning, an optimization of the aperture system is possible without any problems.

The total weight increases slightly to approx. 9kg due to the more massive focuser.
