Mairan's Nebula

De Mairan's Nebula lies just above M42, surrounds the star HIP
26258 at Mag 6.75 which seems to glow in the bright ball of
nebula surrounding it
08/01/15
With the UHC filter M43 jumps out of the background, very
impressive since it darkens the area around it
16/01/15
18mm with UHC filter really makes the nebulosity around HIP
26258 at Mag 6.75 stand out in contrast to the dark background

It's December, so time for Orion!
M43, the Nebula around Nu Ori, HIP 26258
A definite oval, with more of the Nebula towards M42
Much fainter than the Nebula around M42, a halo

Orion nice and clear so going to view it's nebulae with 12mm and
UHC filter
M43 shows a nice shape around Nu Ori, HIP 26258 at Mag 6.75
The star is dimmed throught the UHC filter with hints of colour
fringing if not quite in focus
The nebula appears denser and larger away from M42 and The
Trapezium with a distinct dark lane between them
However, then viewed in 18mm without filter, fantastic, pin
sharp stars and although not so contrasty the nebula really
showed its curled tadpole shape
Viewed again in 12mm without filter, just as clear, are UHC
filters not really effective on this type of nebula?
