Product is carefully packaged very well. Tripod is sturdy and firm, not one of those cheap shaky ones. The OTA is well constructed, all the included accessories for beginner to start with. Doesn't plan to find the human face on Mars with this thing, just try to get a glance at all the celestial planets around us, it serves the purpose. No prior experience to astronomical scope but this thing surprised me for how easy it is to set up: just follow the manual instruction as simple as 1-2-3 and there you go. I can see the moon now with a big wow.Only tested it briefly twice so far but I can get a clear view of Venus Jupiter Mars and Moon of course. Too cold recently had to move indoor. Will continue to test it when gets warmer outside. Will update if I have more experience with this.For this price I really enjoy it.

The ExploraPro 90mm refractor is a decent starter scope package. Three-and-a-half inches of clear aperture, and an f/7.3 focal ratio, which is kind of a sweet spot as far as I'm concerned. With that focal ratio, you can still get some decent wide-angle views, but it also allows for some respectable magnification when conditions allow. The scope is an achromat, so it is going to show a wee bit of false color on the brightest objects like the moon or Venus, but it really isn't much, and some people may not even notice it. For all other astronomical objects, it's a non-factor.The focuser is the basic rack and pinion type, nothing special but works fine. The red dot finder helps but like most straight-thru finders, it can be difficult to use when looking for things higher up in the sky. (I always use an aftermarket RACI finder on all of my scopes...much easier on the neck.) The included diagonal is a nice bonus as well.The tripod is lightweight, and as expected, is subject to vibrations anytime you touch the scope, whether focusing or tracking, even with the slow-motion controls. It's not a terrible tripod, but as most experienced astronomers know, the mount is often just as important than the scope. Adequate would be the best word I can come up with.Comes with a standard dovetail, so the scope can be mounted on another mount & tripod if desired. Likewise, you can mount another dovetail-equipped scope on this tripod as well.The included eyepieces are low end MA's, lower grade than Plossls, but they are adequate. The 20mm and 10mm work fine, but the 4mm I received is next-to-worthless. No eye relief, false color, and extremely small exit pupil make it difficult to use. I would recommend purchasing a Celestron 8-24 zoom...mine works quite well with this scope. The Barlow will double the magnifications of the eyepieces.I haven't yet tried the cellphone holder for taking pictures, and not sure how sturdy it is in actual use.Overall it is a nice setup for the money. And the dovetail allows for interchanging different scopes/mounts if you advance in the hobby. I would recommend this package for kids or adults starting out in the hobby, or for an experienced user who may just want a cheaper scope for quick and easy grab-and-go observing sessions. Four stars.
