Messier 20 (M 20) - Trifid Nebula

Introduction | Map | Sketch | My Best Own Photos | My Own Observations | References || Appendix: My Own Photos

On this page I collect my observations of the galactic emission nebula M 20, called Trifid Nebula, in the constellation Sagittarius.

 

Introduction

The galactic emission nebula M 20 in the constellation Sagittarius is called Trifid Nebula because it consists of three parts. According to Stoyan, most observers are disappointed of this nebula when they see it for the first time, because even small light pollution can "extinct" the nebula.

Size: 15' x 10' (Stoyan)
Distance: 5,000 light years (Stoyan)
Rating: ** (Stoyan).
