Astrophotography Fit
A general-purpose GoTo mount that should be chosen by realistic imaging payload, not headline capacity alone.
iOptron GEM28 Go-To German Equatorial Mount With iPolar And 1.5" Tripod is a midrange GoTo equatorial mount for computerized tracking and guiding.
For long-exposure astrophotography, use a conservative imaging payload. The telescope, camera, guide hardware, dew heaters, dovetails, and cables all count, and guiding performance matters more than the catalog payload number.
Best paired with
- Autoguided refractors or corrected reflectors within conservative payload limits
- Stable tripod or pier and balanced counterweights
- Computer or hand-controller workflow with good polar alignment
Not recommended for
- Payloads at the rated maximum for imaging
- Users who need an airline-portable rig above all else
- Long focal length work without guiding and careful balance
