FAQ - Frequently Asked Questions

Why do I see everything upside down and mirrored in the finder?

That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

What is the difference between an alt-azimuth mount and an equatorial mount?

Alt-azimuth: easy to use, moves horizontally and vertically
Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

What minimum apertures do I need for certain objects?

Moon: from 30 mm
Planets: from 100 mm
Deep sky: from 150 mm

Product information "Vixen Coma Corrector PH for R200SS Newtonian"

The Vixen corrector PH is a 3-element Wynne corrector for demanding applications. Designed for the Vixen R200SS Newtonian reflector, but also suitable for other optics with similar specifications.

The optical design consists of 3 lenses in 3 groups. The corrector provides excellent correction of system-induced coma of parabolic mirrors and the resulting spherical aberration. The corrected field has a diameter of 44 mm, making it suitable for the 24x36 mm format (full-frame DSLR/CCD cameras). This guarantees razor-shape images across the entire field. The lens surfaces are coated with a cutting-edge 99.9% anti-reflective AS coating, which is also used for Vixen's flagship VSD100F3.8.

Turn your Vixen R200SS reflector telescope into the perfect astrograph!

Warning notes

General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
Do not expose the device to high temperatures.
