Alstar 2X TeleXtender Barlow Lens, 1.25 inch 3-Elements Multi-Coated Premium Apochromatic Telescope Accessory for Astronomy Planetary Observation

Alstar 2X TeleXtender Barlow Lens, 1.25 inch 3-Elements Multi-Coated Premium Apochromatic Telescope Accessory for Astronomy Planetary Observation

• Three lens design Barlow lens: The Alstar apochromatic Barlow lens features a three-element design to ensure exceptional chromatic correction and deliver pin-sharp high-contrast images
• Increase the magnification: Insert the premium Barlow lens between the eyepiece and the telescope to achieve increased magnification while maintaining optical quality; Additionally this setup retains the longer eye relief characteristic of eyepieces with greater focal lengths ensuring comfortable observation
• Suitable for Planetary Photography: As optical quality here is critical you should really use a high-quality Barlow lens; Without a Barlow lens planets appear tiny and virtually no detail can be seen; Only by inserting the Barlow lens can planetary images be made to appear a reasonable size
• Aluminium Housing with Rubber Armoured Grip: Premium Barlow lens in the hand you immediately notice that exterior is just as elegant as the interior; The housing is machined from aluminium and there is high-grip rubber armouring in the centre section; This high-quality workmanship ensures a long life
• Brilliant Imaging Performance: Enhanced lens correction directly correlates with improved image quality and sharpness of planetary observations; Consequently the Apochromatic Barlow lens employs a three-element optical design to ensure superior chromatic correction delivering exceptionally sharp and high-contrast images thereby enabling the capture of high-quality planetary photographs
