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)
Ranking: ** (Stoyan)
