Celestron Powerseeker 70AZ vs Celestron AstroMaster 102AZ

We couldn't find enough data on either product to be able to come to any reliable conclusions. We highly recommend that you take a look at some other options in the $90 and $270 budget ranges instead.

The Celestron Powerseeker 70AZ hasn't managed to perform well enough to earn a place in any Refractor Telescope roundups conducted by sources that do their own, high-quality, hands-on testing. That alone makes it a hard product to recommend.

Moving on to the Celestron AstroMaster 102AZ: no sources that perform reliable and objective hands-on testing have included it in their Refractor Telescope roundups, which usually means that a product doesn't make for a good purchase.
