APM – LZOS Apo 254mm/2250mm CNC – LW II Model
The 10″ f/9 Apo is a true observatory telescope. Only one other manufacturer we know of, Takahashi, offer such a large Apo, but with a price multiple times higher. Despite its lower cost, the 10″ offers the highest optical quality and color correction that is possible with today’s lens materials and technology. 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 image 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 one centered. The middle two hole’s center to center spacing is 2.362″ and outer two hole’s spacing is 3.2″ (Astro-Physics standard).
Since this Apo is also rather front heavy, when you place your order APM offers the installation,to the rear inner portion of the tube, the proper weight for the balancing point of your choice for an additional cost.
