Description

Last Friday and Monday were the only two nights with relatively clear sky (more than 80% humidity though) so I imaged the Pleiades, a relatively easy target under such conditions.

This is yet another experiment where I didn't use flats at all (I am never using darks or offsets at such short exposures/low ISOs anyway), relying instead on the raw converter (Rawtherapee) to correct light fall-off.
