About this product
Model: stellalyra_45_cc
Part Number: CC45
4.5" f/12 StellaLyra Classical Cassegrain
This long focal length Mini Classical Cassegrain telescope 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.
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.
