The SkyWatcher 9×50 Finder to C Adapter connects C and CS mount cameras to SkyWatcher, Orion and most Celestron 8 x 50 & 9 x 50 straight through finders.

Description

The SkyWatcher 9×50 Finder to C Adapter connects C and CS mount cameras like the QHY guide and ZWO mini cameras to SkyWatcher, Orion and most Celestron 8 x 50 and 9 x 50 straight through finders.

Most Celestron finders are the same as SkyWatcher, and have 11 fine threads cut into the rear of the finder tube. However some are different and we now have a separate adapter for those Celestron finders with 8 coarser (1mm) rear finder threads. Simply remove the eyepiece and holder to check.

[SPC900 / SPC800 to Sky-Watcher and GSO to C & GSO to T adapters are also available ]

Please contact us prior to purchase if you are unsure 🙂

Tests have confirmed that guiding with the SkyWatcher 9×50 Finder to C Adapter is successful at focal lengths of 1500mm and more and is seeing dependent.

Stability is excellent if screws are tightened firmly and cables tied up.

Using a 9×50 finder as a guide-scope reduces the weight and complexity of your imaging setup and the wide field of view practically guarantees finding suitable guide stars.

Guiding software prefers a less than perfect star image, so the centre of the star mass can be better calculated. Most 9×50 finders are optimal for this “as-is” whereas small refractors can be, if anything, too sharp.

Please read this article “Thoughts on Auto-Guiding” for a more in depth analysis of the subject, which is borne out by my tests.

A great purchase. Allows you to adapt a view finder into a guide scope, saving not just money but also lots of weight when weight becomes important depending on the mount you are using. Works great with the SX Lodestar x2 and QHY5L-II ccd guide cameras.
