Smart telescope field of view simulator
Pick up to three telescopes and a target: the frames are drawn to scale over the object, so you can see what fits in one shot and what needs a mosaic.
Frames are native telephoto fields, without mosaic.
Native field of view of every smart telescope
Width × height of the telephoto frame in degrees, from the makers' figures read on November 9, 2026. "Fits" means the whole object fits in one native frame.

Questions
Which smart telescope has the widest field of view?
In our data, the ZWO Seestar S30 Pro: 4.01° × 2.26° native, enough for the Andromeda Galaxy in one frame. Mosaic modes on several models go wider.
Which smart telescope shows planets biggest?
The one with the finest image scale. Jupiter at its largest spans about 50 arcseconds: about 54 pixels on the Unistellar Odyssey (0.93″ per pixel) and about 12 on the Seestar S30 (4.02″).
Is a wider field of view better?
For large nebulae, star clusters and the Andromeda Galaxy, yes. For planets and small galaxies, a narrower field with a finer image scale shows more detail. Our guide to the specs explains the trade-off.
How accurate is this simulator?
Telescope fields come from the makers' stated figures, or from the frame size and image scale when only those are published. Target sizes are approximate catalog values: real nebulae fade gradually, so edges are a matter of exposure.
