Description

TS Optics 2 "- 2.5x APO-Barlow

The TS Barlow increases the magnification of your 2 "or 1.25" eyepiece by a factor of 2.5. The premium 4-element optics are completely multi-coated for optimum image brightness, high contrast and color-true reproduction. The 4-element design also allows use on very high-speed telescopes, such as on f / 4 Newton's.

The Barlow lens is high quality processed. The four lenses are stored in a solid aluminum housing. Inside, the Barlow is blackened as best as possible, so that even in lunar and solar photography (with sun filter) no reflexes.

The clamping of the 1.25 "and 2" accessories is done by a ring clamp. The fixation takes place gently and precisely on the optical axis.

On the telescope side, the Barlow lens offers a 2 "filter thread, where you can screw in all commercially available 2" filters.

Photography: This Barlow lens is also a high-quality photographic converter that extends the telescope focal length by a factor of 2.5. The 4-element design ensures a very high sharpness on the axis and especially in the field. This is an important advantage over simple 2-element barlow lenses. Even with full-frame cameras, you'll be able to achieve sharpness right up to the edge.

Good option for FSD drivers with a thin skin
Color: Black
Works great. Holds the phone very well and can be repositioned very quickly to accommodate various driving modes like laid back and deep or focus edge of your seat with getting yelled at by FSD (not really self driving)

'A Must Buy'....!!
Color: Black
I have had multiple Magnetic phone mounts, this is by far the best one yet. For the price, it is a 'must' buy, it fits perfectly on corner of screen, very tight, never an issue with bumpy roads, sharp curves, etc. You can use mount at different angles, whatever suits your needs.
