Refractor Apo ED Tecnosky 125/975mm (FPL53 et Lanthanum)

Apo ED Tecnosky 125 / 975mm Refractor (FPL53 and Lanthanum)

After the success of the 102/700 FPL53 refractor, here is his worthy successor with increased optics at 125mm diameter.

With the use of two high quality glasses, synthetic fluorite FPL53 and lanthanum, chromatic aberration is extremely correct.

The focal ratio F / 7.8 makes it particularly suitable for planetary observation and double stars!

If equipped with a 1x corrector or a 0.8x corrector / reducer (F6.24), it becomes an excellent tool for deep sky photography with CCD or SLR cameras

The tube is made entirely of aluminum, with sharp-edged diaphragms inside and an opaque paint applied to eliminate glare.

The 2.5 "focuser is equipped with a rack (the same as is mounted on the 115mm triplet) and supports large loads with extreme precision.

The rack avoids those annoying slips that are present on the economic crayford focuser. It guarantees very high accuracy also with the use of autofocus system

The focuser also has a graduated scale on its inner tube and the classic and very practical micrometric focus control of 1:10.

A pair of CNC machined rings and a Vixen bar complete the equipment.

Technical characteristics:

- APO FPL-53 doublet and Lantanio doublet with FMC treatment
- Aluminum tube with internal diaphragms and retractable fender
- 2.5 "Focuser with rack and pinion adjustment 1:10
- a pair of rings and a vixen type dovetail
- weight 7.6 kg
