PHD2 and planetary

Recommended Posts

What sort of long exposure are you planing to use?

Most planets will saturate your sensor in any sort of exposure that requires guiding. Even faintest planets will probably saturate in over 5-6s second exposure, and there is no much point in guiding such short exposures.

as exposures are normally in the 10's of milliseconds range, I guess that the intention is simply to track the planet in order to keep it in the centre of the frame? This isn't so important as the individual frames can be aligned on the disk using software during the processing stage.
