binoculars

Celestron makes some of the world's greatest telescopes, but this is not one of them. It's fine for peeking into the neighbor's window across the street or looking at the a large, bright object in the sky like the moon. But for serious stargazing, one shouldn't expect much from this telescope or any telescope in this price range. No telescope in this price range is much good for looking at stars or other faint objects. A really good pair of binoculars for around the same price would probably give you more enjoyment and be more versatile. Just lie on the ground and look through both eyes at the moon or constellations, and then take them to the ballgame the next day. And try to get away from city lights. If you do get binoculars, make sure that the second number is at least 7 times the first number (e.g., get 7x50 binoculars, but not 7x35) and that they have fully multi-coated lenses.

I wouldn't recommend this. Its very blurry and can't even focus on the cows out in the field let alone all the way to Mars.

Just a short addendum to my previous firstscope review.

I added a Celestron 2x Barlow lens from amazon via adorama.

This increases the magnification using the 10mm lense to 140x.

Unfortunately, at 140x, the scope doesn't provide sharp
focus of viewed objects. The moon is large but washed out,
very low contrast. Saturn couldn't be brought into focus, it
was 2x larger but fuzzy. I didn't get to try Jupiter.

I wouldn't reccomend adding a 2xBarlow to this scope, I would
live with the 10mm and 20mm lenses and save my money for
binoculars or a better scope in the future, or buy a
subscription (at least part of one) to the wonderful Astronomy
or "Sky And Telescope" magazines.
