HELIX Artesky Off-Axis Guide

Off-axis guider is a really handy and exceptional tool for astrophotographers. Off-axis guider is an innovation that is nothing short of brilliant, we can screw it or insert it into the focuser of our telescope.

A small prism diverts a very small amount of light from the telescope into a separate tube, where your guide camera or illuminated reticle eyepiece is located.

Thanks to this, you can easily correct any tracking errors during the shooting time of your camera.

Result? Perfectly round stars!

Why It's Sometimes Better to Shoot With Off-Axis Guiding

With an off-axis guider you will have perfect photographs in an instant; photos that require long shooting times require precise tracking, such as those guaranteed by the HELIX Artesky guide, an essential tool for astrophotographers.

You will get perfect photos in no time!

Guide scope or off-axis guider?

For many it just depends on personal taste, however by using long exposure times, the position of the guide scope and the telescope can undergo minimal movements, even with reflecting telescopes.

Off-axis guider is recommended on telescopes with long focal lengths where a parallel guider is often not sufficient to correct all tracking errors and not only (for example mirror shift in Schmidt Cassegrain telescopes)

It can also be used profitably on refractors, while on Newtonian telescopes it is only recommended in combination with a Rowe-type coma corrector that extracts the focus.

An off-axis guider easily solves this problem as there is only one optical path.
