Sampling
Significant Undersampling ⚠⚠⚠
With this setup small stars may appear squarish and larger ones blocky. Try a camera with smaller pixels or adding a barlow into the mix. A more powerful telescope with a longer focal length will also help.

Camera Chip FOV 3.59° x 2.87°

Preview Targets by Relative Scale


*Note that planets apparent size is based on oppositon and will change throughout the year depending on their proximity to Earth.

Click on a telescope, camera or combination in the yellow boxes below to preview how large near and deep space objects will appear and whether the sampling is good for astrophotography. It’s easy! You can also enter in the specifications for any items that aren’t listed here.


The goal for astrophotographers is to choose a combination of telescope & camera that is neither under or oversampled. Note however that a little of either is ok and post processing can improve the end result. For example, Dither & Drizzle improves undersampling. Noise reduction & sharpening improves oversampling.
