Description

The central part of IC1805 taken in Halpha wavelength under my heavily light polluted sky. Finally a good seeing and good transparency after some months of fog or persisten jet-streams. Best frame tells a FWHM of 2.4" or ~3.7 px.

Plate solving outputs an image scale of 0,65"/px and 1707 mm of focal length.

Finally an image that satisfy me both in resolution achieved as well as in smoothness of the darkers parts.
