TS-Optics 2" Barlow 2.5x APO 4-element design - short construction

TS Optics 2" Barlow 2.5x APO 4 element design - short construction

The TSB225 amplifies the magnification by a factor of 2.5 and provides a very good illumination for 2" eyepieces and also for astrophotography.

♦ 2.5x focal length extension - the magnification is significantly increased.
♦ High quality 4-element APO construction for very good sharpness on the axis and in the field for sharp observations and astrophotography.
♦ The Barlow is at the same time a photographic 2.5x converter for photography through telescopes with 2" eyepiece.
♦ The 2" Barlow has a screw-in thread on the telescope side for 2" filters, e.g. for fog filter for contrast enhancement.
♦ The clamping of 2"and 1.25" accessories is done by ring clamping. The 1.25" adapter is included.

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 TSB225 offers a 2" filter thread where you can screw in all commercially available 2" filters.

Photography with the TSB225:
This Barlow lens is also a high-quality photographic converter, which 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.

We offer suitable adapters for the camera connection in the accessory area.
