Recommended Accessories

The following optional accessories will enhance your enjoyment of this telescope:

A 2x Astro Essentials barlow increases magnification of the included eyepieces. When used with the 10mm eyepiece, magnification increases to 100x. With the 26mm eyepiece, magnification is 38x. 

A 0.9x 1.25" Moon filter reduces glare when observing the Moon for more comfortable viewing. 

Most astronomers own three or four eyepieces. We recommend you become familiar with the two supplied before ordering more but are happy to advise if you are in a hurry. 

We also recommend a warm coat, thick socks and a woolly hat!
