On this page I collect my observations of the galactic reflection nebula NGC 2261, called Hubble's Variable Nebula, in the constellation Monoceros/Unicorn.

 

Introduction

The galactic reflection nebula NGC 2261 in the constellation Monoceros / Unicorn, is called Hubble's Variable Nebula because it changes in detail. But this is only visible in large telescopes. The special thing about this nebula is its shape, which resembles a comet.

Size: 1.5' x 1'(Stoyan)
Distance: 2,500 light years (Stoyan)
