StellaLyra 4.5 Inch f12 CF Mini Classical Cassegrain Carbon Fibre Telescope OTA

Product Description

This long focal length Mini Classical Cassegrain telescope optical tube is perfect for those requiring an ultra-portable Cassegrain to observe or photograph smaller targets, such as planets, close-up Lunar, double stars, small nebulae and comets. A perfect option for higher power viewing without having to use uncomfortable short focal length eyepieces or a barlow.

It features a carbon fibre main tube and a fixed-position primary mirror, eliminating the image shift associated with other telescope designs. It also features an EAF-compatible 2" dual-speed rotatable Crayford focuser. A blackened interior reduces stray light for maximum contrast.

It is fitted with a Vixen-style dovetail mounting plate for easy attachment to a wide variety of popular mounts.
