  • Fun entry telescope

    from Calgary, AB on March 6, 2017

    For the price, you know that this is an entry level telescope. It is easy enough to assemble, requires you to point it at objects in the sky yourself, and teaches you how to focus and determine good nights for "seeing". Make sure you tighten all the bolts to keep the telescope steady. With the supplied 20 mm eyepiece, you can explore the moon, see the crescent in Venus, and I can see Jupiter and its moons from my backyard near downtown on the Prairies. The 4 mm is harder to use in this situation due to light pollution (there is too much refraction in the atmosphere and everything appears fuzzy), but I have used it in better conditions and its okay. I will say that the 3x Barlow lens is not all that great. I get some chromatic aberrations even in darker skies. I went on to buy a 6 and 12 mm Celestron Omni eyepieces and they are a good fit. With these, I can make out Jupiter's larger bands again from a light polluted backyard! The only issue I can see with this telescope is you are going to use it, could love astronomy, and then move on to something bigger!
