Which should you buy?

Buy the Star Adventurer 2i if you travel with the tracker, like phone control for intervalometer and tracking modes, and want the lightest head for carry-on luggage; it is the most popular entry tracker for a reason. Buy the SkyGuider Pro if polar alignment is the part of the night you dread, because the built-in illuminated scope makes it faster, and the declination bracket lets you nudge framing without touching the ball head. Capacity is identical, so choose on the alignment workflow you prefer, and budget a power bank for the iOptron.

Common questions

Can either tracker carry a small refractor?

A very light one with a small camera stays under 11 pounds, but neither has room for a guide scope on top of that, and both work best at half their rated payload. For a refractor plus guiding, step up to a GoTo mount.

How long can I expose on either?

With careful polar alignment, two to three minutes at wide angles and about a minute at 200 mm before trailing shows. Better polar alignment, not a better tracker, is what extends that.

Does the Star Adventurer need the app?

No. It runs from its own buttons, and the app adds convenience for tracking rates and time-lapse control. The SkyGuider Pro has no app at all.

Which is easier to polar align?

The SkyGuider Pro, because the illuminated reticle is built in. The Star Adventurer needs its illuminator attached and aligned, which is a small extra step each night.
