Gskyer's AZ90600: a 90/600 refractor with multi-coated green optics on an alt-azimuth mount and stainless steel tripod, with 25, 10 and 5 mm eyepieces, a 3x Barlow, a 6x30 finder and a 48-degree BAK7 erecting prism.
The AZ90600 is a 90 mm (3.5 in) refractor at 600 mm, f/6.7. Ninety millimeters gathers about 27% more light than an 80 mm, enough to show Saturn’s Cassini Division on a steady night and more detail in bright nebulae.
Gskyer publishes a specification table: 25, 10 and 5 mm eyepieces for 24x, 60x and 120x, a 3x Barlow, a 6x30 finder, a 48-degree erecting BAK7 prism, a hook dovetail plate, a 1.27-inch stainless steel tripod adjustable from about 31.5 to 49 inches, an angular field of 1°36’ and a resolution figure.
One bullet calls it a “reflecting telescope”. It is a refractor; the rest of the listing says so.
Maximum magnification is given as 360x, the 5 mm in the 3x Barlow. A 90 mm aperture is good to about 180x; 120x is the realistic planetary power.
The 48-degree erecting prism turns the image upright, so it doubles as a spotting scope.
On November 7, 2026, Amazon.com listed it at about $270 from a third-party seller.

A refractor. The title and the specification table say so; one bullet says "reflecting telescope" by mistake.
An erecting diagonal that tilts the eyepiece 48 degrees and turns the image upright, chosen for daytime viewing. Gskyer names its glass, BAK7.
About 180x on a good night, twice the aperture in millimeters. The 5 mm eyepiece (120x) is the planetary eyepiece; the 3x Barlow with it (360x) is not usable.
