Join us on Thursday the 21st November for an in-store demonstration of the Sigma fp Camera! There will be a variety of Sigma Global Vision products and accessories available to show as well as a Sigma technical adviser here to answer any questions you may have. The events is from 10.00 to 17.00, and a full range of Sigma lenses will be available to inspect and try out.

What can I see with this telescope?
Open up the universe with this great telescope. See the rings of Saturn, passing comets, the face of Jupiter and celestial bodies even further away. The telescope can reach 180 times magnification for viewing far off objects. With an aperture of 76mm, fully coated lens and ability to gather 118 times the light of the human eye you get a clear, bright image. This telescope comes with two eyepieces, one with 35 times magnification and one with 175 times magnification. There is also a three times Barlow lens which can be used with any of the eyepieces to increase their magnification.
Why choose a reflector telescope?
Reflector telescopes are open at one end and use mirrors to collect and focus light for the image. Typically, the apertures of reflector telescopes are larger than their refractors. This means they can see further and fainter objects and have a wider apparent field of view. The bodies of the reflector telescope can be made smaller, all while maintaining the same level of magnification. Reflector telescopes don’t suffer from chromatic aberration, colours appearing around an image, like some refractors. Reflector telescopes display the image upside down. This is normal for astronomical telescopes, but will be noticeable with terrestrial viewing.
How easy is it to assemble?
Quick and easy to assemble without any tools this telescope comes with a finderscope and steady tripod. There is a tray under the telescope to store your alternative eyepiece and other essentials. It is easy to pick up and move to get you in the best place for the perfect image. The Barlow lens can be attached between the focuser and the eyepiece and triples the magnification of the eyepiece.
What sort of mount does the telescope use?
This PowerSeeker telescope comes with an Altazimuth mount - great for smooth and accurate movement. Altazimuth mounts allow the telescope to move up down and side to side and are great for terrestrial use allowing you to adjust the position and follow moving objects easily.
