This H-alpha narrowband image from last night, shows a large area around
the "Cone Nebula". Lots of nebulosity around there.
Cone Nebula, H-alpha
Note the "Hubble's Variable Nebula" at Five a clock position.
(A small cometlike dot in the image)
A Starless version to show the nebulosity better. A grop from the center. This lens is very sharp, even full open @f1.8
Weather in this winter has been #&%@$£2 and last night was no exception.
After four hours I managed to save four 20 min. exposures,
others were ruined by the speeding clouds.
