Product description

Tecnosky proposes a gigantic short-focus achromatic refractor for deep-sky observation and narrow band photography.

The optic consists of a doublet with multi-layer anti-reflection treatment spaced in the air; the lenses are inserted in a sturdy collimable aluminum cell.The intubation is made in Italy, in 3mm anticorodal aluminum with internal diaphragms.

The focuser is a sturdy 2.7 "Titanium Tecnosky.

Instead of using two rings we opted for two sturdy (but lighter) crescents connected to a long losmandy Geoptik bar.

The total weight of the instrument is only 17kg

Our tests confirmed very good global optical correction and manageable chromatism on the Moon and planets with a Baader Semi Apo filter.

Despite being a telescope for use at medium-low magnifications on deep-sky, it still provided us with a detailed view of the Moon and Jupiter at 170x (numerous bands and the red spot visible)

This refractor lends itself very well to be transformed into a gigantic h-alpha telescope, for example with a Daystar Quark filter; we can supply the 75mm Baader ERF with aluminum cell to be mounted internally

On request also available with 1800mm focal length
