Lacerta Illuminated Polarscope for Fornax-52 Mounts & Vixen Polarie
Lacerta Illuminated Polarscope for Fornax-52 Mounts and Vixen Polarie Mount (when used with the Lacerta Off Axis Holder for Vixen Polarie)
It is always easier to use an iluminated polarscope than one without illumination. You can make polar alignment even more comfortable if you add the PolAmi Polarscope Amici Prism that is available separately.
Please note, this illuminated polarscope is not directly compatible with the Vixen Polarie Tracking Mount; it should be used in conjunction with the Lacerta Off Axis Holder for Vixen Polarie.
Above image shows the new version with the included alignment adapter that features six thumbscrews that make it easy to adjust alignment.
Above image shows the Lacerta Illuminated Polarscope installed on the Lacerta Off Axis Holder for Vixen Polarie (optional). Latter is available separately and not included with this product.
Please note, since the above image was taken, there were some changes in how the polarscope attaches to the holder. The latest version doesn't have a thread, but it comes with an alignment adapter instead that has a thread.
The included alignment adapter also allows use of this polarscope with the Fornax 10 Lightrack Mark II.
HOW TO USE IT
The fifth image shows the field of view of the polarscope. Align the directional line to point at Kochab in Ursa Minor, then move your mount so that Polaris falls into the small circle. It's done.
(Don't be mistaken, the asterism in the field of view is not part of the Big Dipper, it is four stars of the constellation Octans to be used for polar alignment on the Southern hemisphere.)
Please note, main image is for demonstration only, the actual threaded adapter might be different... (the last version came with aluminium housing and 3 thumbscrews for easy alignment...)
