Description

Since I don't have any equipment to continue my imaging work, I have organized my image archives. This time I made an image collection out of the planetary nebulae imaged by me. I'm trying to show here, how large they appear to be in the sky. There is an image of the Moon as a scale in the posters. The Moon has an angular diameter of about 30 arc minutes, that's equal to 0,5 degrees.
