APM - LZOS Telescope Apo Refractor Astrograph 100 f/6 CNC LW II - 52mm - 3.5"SL

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 / reducer for full  format CCD
offers a image circle of appropriate size.
This TMB 100F/8 is not only a wonderfull powerfull visual apo for lower
power widefield observations and highest power, highest contrast
planetary and douple star observations, but also a superb imaging
maschine. By adding the matched designed full format fieldflattner it will
offer you pin point stars across the entire field to the outer edges
either by use of new larger CCD cameras or medium format cameras like
the Pentax 6 x 7.
