M76



M76 / NGC650-651 - The Little Dumbbell Nebula
Constellation - Perseus
Planetary nebula
Distance - 3900Ly
Mag 10.1

Date - 14/1/13
Seeing - Antoniadi III
Transparency - poor
SQM 19.95 (LM 5.4)

Telescope - 16" f/4.5
EP - 10mm Pentax XW x189 (TFoV 0.2˚)
Filter - Lumicon OIII

Sketch notes
Fairly easy to find even without a filter but both UHC and OIII filters really helped bring out the structure and showed the almost rectangular shape of the central nebula.
Poor seeing and transparency last night so I kept the magnification fairly low to make the sketch but I think it will be worth trying higher mags in a steady sky.
