Messier 27 (M 27)

On this page I collect my observations of the planetary nebula M 27 in the constellation Vulpecula/Little Fox.

Introduction

The planetary nebula M 27 in the constellation Vulpecula/Little Fox is called Dumbbell Nebula because of its shape. According to Stoyan, it is considered as one of the most beautiful nebulae for telescope observers. Visually there was not much to see for me so far, except with the PS 72/432 in France under a darker sky (and in Betz with a bigger telescope), but photographically I was a bit more successful. With the Explorer 150PDS I saw more or less a square with round corners; of course, did I not see the colors. The view in the StarTravel 120/600 was nearly quite as good. In my electronic telescopes eVscope, eVscope 2, and Vespera, M 27 is one of the nicest sky objects.

Size: 8' x 4' (Stoyan)
Distance: 1,200 light years (Stoyan)
Rating: ***** (Stoyan).

My Own Observations

Observations Summer to Autumn 2016

• Regrettably, I was just able to detect a glowing something, but nothing like a dumbbell. Location, observation date, and telescopes used are unknown/forgotten.

Observations September/October 2018

• September 17, 2018 (Sumène, France: PS 72/432, AZ Pronto Mount): M 27 (Dumbbell Nebula) seen quite well at different magnifications.
• October 5, 2018 (Betz, France: unknown telescope): M 27 seen large and beautifully.

Observations August 2019

• Aug 26, 2019 (Mühlhausen/Kraichgau: Explorer 150PDS on Star Discovery GoTo Mount, StarSense): M 27 (Dumbbell Nebula) observed at different magnifications, seen well.
• Aug 30, 2019 (Mühlhausen/Kraichgau: Explorer 150PDS on Star Discovery GoTo Mount, SynScan WLAN): M 27 beautifully seen with 10 mm and 7 mm eyepieces; more or less a square with round corners, the colors, of course , not seen...

Observations September/October 2019

• October 3, 2019 (Sumène, France: StarTravel 120/600, AZ Pronto Mount): M 27 (Dumbbell Nebula; 24, 10, 7, 4 mm) nice, large, maybe a little square-like...
• Oct 31, 2019 (Erkerode: Skymax-127 on AZ Pronto Mount): M 27 (32, 24, 16 mm) appears as a large, more round (perhaps a little elongated...) glow, seen well - located above Sagitta
