We were able to align on Polaris (Alpha (α) Ursae Minoris) in seconds using the plastic sighting tool supplied and the smooth optional Fine Adjustment head. igned properly so as not to interrupt the orientation of the camera. The "U" for the POLARIE U stands for the cross-section of the product. you change the setting for a different speed, a smartphone or other wireless device and application software are required.

You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is.

The direction of the slide power switch implies the directions of rotations in the northern or southern hemisphere. Right after turning ON th Duration of operation - About 4hours: at 20 C (68 F) degrees temperature, a 1.5kg (3.3 lbs) loading weight with use of Alkaline batteries Which one should you invest your hard-earned money in for astrophotography? That will depend on the type of user experience you are looking for, and my goal for this article is to highlight the key differences in the user experience for each mount. We then attached the optional polar scope that enabled us to refine our polar alignment by visually aligning Polaris and two other stars against the image printed within the polar scope. A small latitude scale, graduated from 0° to 70°, is built into the left side of the Polarie. It can be illuminated in red using the rotating switch. Although the scale is rather coarse (the graduations are in 5° increments) it is more than adequate for preparing for polar alignment through the sight hole or polarscope. Polarscope

It is sold as a standalone unit that does not include an equatorial mount or a dedicated polar scope, which are optional extras. For this review we were loaned both additional items. Refine the polar alignment by centering Polaris (or σ-Octans) in the field of view of the Polar Sight Hole Here you can see a detailed view of the Vixen Polarie. A detailed view of the Vixen Polarie. Image from the Polarie User Manual.This is a neat solution, particularly if you already use a power bank to power an anti-dew heating strip to keep your lens from fogging in cold and humid environments. Weight And Portability When we unboxed the Polarie we found a very compact and reasonably light mount, in fact 20% lighter than Vixen’s previous model. Power for the Polarie U comes from four AA batteries or an external power supply connected via USB-C. Vixen says four new AAs will last seven hours at 68 degrees Fahrenheit (20 degrees Celsius). Im not sure if my stuff is not faulty in some way – at least the fine tune knobs, but i needed to fine tune the alignment in every 5 shots. Which is of course exhausting.
