APM Telescopes

The 228mm Apo is of a size which is really no longer transportable, but rather is an observatory class telescope. Its optical quality and color correction are as perfect as with our smaller models. New observing thresholds are crossed with an instrument of this size class and quality. You will see the planets with details as you can see only on the very best CCD images. As well, it's an excellent CCD imaging machine in its own right.

The tubes are made in Germany with non-compromising mechanical quality. The dew cap slides smoothly over the tube without producing any paint scratches. The focuser is a full 3.5" size. It rotates smoothly and with zero image shift. This zero shift rotation is very important when your camera has already achieved its best focus and you would like to rotate it to the best position. The finder bracket has a quick exchange style screw system and is mounted on the rotatable focuser, which allows focuser rotation to bring the finder scope to the most comfortable observing position. The focuser comes with large anodized focuser knobs and moves extremely smooth when racking. The focuser comes with a screwed on 3.5" / 2" adapter and an 2" / 1 1/4" clamp ring style adapter to protect your eyepieces and diagonals from scratches. The tube rings are flat on both sides and offer five tapped 1/4 inch holes perpendicular to the tube line with the outer hole¶ïs center to center spacing of 3.2" and 2.362". The center tapped hole can be used for different mounting plates with only a single center hole. The tube¶ïs internal baffles are matched for a large useable photographic field. This system with the matched field flattener for full format CCD chips and film cameras up to 6x7 cm offers a image circle of appropriate size.

Since this Apo is also rather front heavy, when you place your order we offer the installation, to the rear inner portion of the tube, the proper weight for the balancing point of your choice. That work cost some additional money. Please talk with us about this
