Description

Iris Nebula (d~1300ly)
and Ghost Nebula (d~1470ly)

Constellation: Cepheus

In 4 nights I got a bit over 8h of good data on these targets. Unfortunately I had to discard 2h worth of data mainly due to guiding issues in the 4th night of imaging. It is the first time I reduced star sizes in Pixinsight with the help of a Stars Contours Mask and Morphological Transform.

I hope you enjoy this image!
