Overview

The Sky-Watcher SkyMax 102 pairs a 102mm Maksutov-Cassegrain optical tube with the AZ-GTi, a lightweight computerized alt-azimuth mount that connects to your smartphone via its own WiFi signal. The Mak's 1300mm focal length at f/12.7 makes it well suited for lunar detail, planetary observing, and double stars, where high contrast and long focal length matter more than wide fields. Do not expect sweeping deep-sky views; the narrow field of view is a genuine tradeoff for that planetary sharpness.

The whole package weighs under 6kg, fits in carry-on luggage, and sets up quickly without the complexity of a polar-aligned equatorial mount. GoTo alignment through the SynScan app gives you access to a full sky catalog, and the dual-encoder Freedom Find system lets you move the telescope by hand without losing your alignment, which is a genuinely useful feature in the field. At $765, this is a capable, portable planetary scope with modern convenience built in.

It is best suited to someone who wants a grab-and-go setup for the Moon and planets, and who values being able to control the mount from a phone rather than fumbling with a hand controller in the dark.

A great travel or starter scope package.

I've been an amateur astronomer for several years now. This is my 4th telescope, and I'm pretty happy with it. The tripod and mount are great. I like how the motorized mount uses an app (something I was initially weary of); it actually simplifies and speeds up the alignment process. The OTA (the tel...

Wish I'd just bought this earlier...

This is my 5th telescope, and I could have saved some time, expense, and headache by simply starting here. I also have an 8" Dob and had and sold an 8" goto SCT, plus a couple smaller guys. The dirty little secret of visual astronomy is that there are really only 7-8 real showpiece amazing sights to...

2 versions of telescope.

Mount is great, no issue there. Skywatcher apparently has 2 version of the 102 Mak telescope. The one sold separately from the mount has optical adjustment/collimation screws. The one sold with the mount does not, and cannot be adjusted. I would not recommend getting this tube/mount combo for that r...
