Apo 105/650 LW

APM (LZOS-Design)


In responds to our customers requirements, we have now created a new run of lightweight tubes with the following optimized design: newly designed retractable dew cap, to facilitate quick focusing a sliding draw tube with attached 2" Feather Touch focuser which moves into the main tube on new teflon straps and secures with locking hand screw against any tilting . This new combination allow to use any binoviewer with any diagonal mirror without optical path correctors and still achieve focus. Also included is a Vixen style mount rail. This new ultracompact and lightweight model is fully airline portable. It offers you a 2" wide field eyepieces maximum FOV of 4.2 degrees. Screw into your 2" low power eyepiece a 2" nebulae filter and see the North America Nebula with contrast as never before.

The optics possess such exceptional chromatic and spherical correction that, in excellent seeing, you'll be able to push magnification beyond traditional extremes for planetary and double star observing with the greatest of contrast and resolution. For imaging we recommend, based on our customers experiences, use of a TeleVue 0.80x field flattener/reducer for best edge performance.

Apo 105/650 CNC-LW II

APM (LZOS-Design)


The APM (LZOS-Design) 105mm f/6.2 with the new lightweight and compact CNC Tube and new 3.5" Starlight focuser utilizing a 1:10 fine focus is not only a most powerful visual telescope but also one of the best wide field astrographs on the market. General information about the new APM (LZOS-Design) 105/630 CNC -LW II machined tubes:

These 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 a 2"/1.25" clamp ring style adapter to protect your eyepieces and diagonals from scratches. The tube rings are flat on both sides and offer three tapped 1/4-20 inch holes perpendicular to the tube line with the outer two hole's center to center spacing of 60mm (2.362"). The center tapped hole can be used for different mounting plates with only a single center hole. The tube's internal baffles are matched for a large usable photographic field . This system with the matched field flattener for 6x7 medium format film offers a image circle of appropriate size.
