Guidescope Guide Star Apo61

Is that still a guiding scope or already an apochromatic refractor ? The fact is that the Guidescope GS61 contains a lens with FPL-53 glass , whose excellent optical properties enable sharp stars for tracking control (guiding). The GS61 can be used on refractors with a focal length of 700 to 1200 millimeters.

With the optional Flattener Flat61 , the GS61 can even be used for astrophotography - ideal for use with small photo mounts.

The helical focusing is done by moving the dew cap with the integrated lens: loosen the ribbed lock ring, move the cap until the focus is reached and tighten the lock ring again. At the rear end, the GS61 has an extendable extension tube. With the GS61 it's really no problem to find the focus position!
