  • $\begingroup$ Answers to this question will be almost entirely opinion based. There is no clear-cut way of saying which telescope will be better than the other. As such, this is not a good question for this site. $\endgroup$ – zephyr Jul 18 '17 at 12:47
  • $\begingroup$ Definitely not the first. It's a toy and will be totally useless. Contact an astronomy club if you can and get some advice from them. You may be able to try some telescopes at a meeting, and someone may even have a telescope that they are willing to sell. $\endgroup$ – Mick Jul 19 '17 at 21:55

Of the two, I would go with the Celestron - it's from a named and respected manufacturer with sensible specifications and relevant additional equipment. The eyepiece selection is thoughtful.

However, you pay the price because the Celestron's focal length at 400mm is much more limited. The best magnification you'll be able to get is 40x without a Barlow (good for the Moon but rather anaemic for the planets).

The other scope promises much higher magnifications but I worry that the manufacturer's name isn't stated, that there seems to be a number of redundant extra items and about the overall build quality.

Personally, I would consider the https://www.bhphotovideo.com/c/product/485261-REG/Celestron_21061_AstroMaster_70_AZ_2_7_70mm_Refractor.html as an alternative, though it is a little more expensive.
