  • Very easy to use & crystal clear presentation
Size: Telescope 90900
I have been using telescopes for a while now but my previous model had a smaller aperture & 600mm focal length which was decent for learning the basics but I couldn't see a lot of detail. I decided to order this Gaterda telescope that has a large 90mm aperture with a 900mm focal length & the difference is absolutely AMAZING! There is so much more magnification with the 900mm focal length & I can see so many more details. This telescope comes with two eyepieces (25mm & 10mm) plus a Barlow lens that can triple (3X) the magnification power of each lens which is up to 270X magnification. The visual presentation is very clear & the magnification makes the moon seem close enough to reach out & touch! The telescope comes with a finder scope which makes finding constellations very easy & the zenith mirror makes viewing through the telescope very comfortable because I do not have to crane my neck. The lenses are FMC coated which reduces glare & provides a very sharp image. The tripod is made of stainless steel & feels very durable. It is very sturdy & has adjustable legs that can be locked into place by tightening a screw knob on each leg. The legs also hold a small accessory tray to contain the various lenses when not in use. The telescope comes in a nice padded carrying case that has sewn-in handles & an adjustable shoulder strap. Inside the case, the barrel of the telescope can be wrapped in the custom padded section & secured in place. Hook & loop bands are sewn inside to hold the tripod securely. A matching zippered case is provided to hold the telescope lenses & accessories. The telescope is very easy to set; it literally took about 3 minutes to set it up & about the same amount of time to break it down & store it back in the case. Overall, I'm very impressed with the quality of this telescope. I like that is easy to set up & use. The visual presentation is very clear & I really like the way it looks with the stainless tripod, silver barrel and the red accents. Having a padded case to store it in is awesome as well! I would definitely recommend this telescope to others. ... show more

  • Nice setup, optics are average
Size: Telescope 90900
This is a pretty complete kit, with a large telescope and a nice enough tripod - especially for the price. The included case holds everything well and allows easy transportation. Unfortunately the optics aren't very impressive. That's not to say they are bad, they just aren't great - even compared to the latest cheap spotting scopes or binoculars. All I have to compare it to telescope wise is an Orion reflector that is over 20 years old. Granted they are different price points, but I expected similar if not much better optics given how much glass optics have improved over that time. This isn't a bad telescope, the price is reasonable and it does work. But I would have to recommend you do some comparison shopping before settling on it. ... show more

Size: Telescope 90900
I was very disappointed with this product. The image quality was poor and lacked clarity, making it very difficult to see anything. I decided to return it because, despite multiple attempts, I was never able to view anything clearly
