Today a small summary of the work from 2018
Overview of all planetary nebulae in one photo

This collage shows at the same time showing the differences in the angular size of all of this objects.
Sizes of objects are indicative - different sources showing diffenert size of the objects depending if its including external nebula layer or not.
I was trying to describe the size on the picture based on the catalogues and setup scale calculation.
The photos were made in technique tof short exposures with the times of single exposure not exceeding 12 seconds.
The stars in the background are of course a random composition created from the photo of Messier 27
