Cone Nebula area, NGC2264

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.
False color H-alpha version.
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.

Camera, QHY9 astro camera
Guiding, QHY5 and PHD-Guiding on LX200 GPS 12"

IC443 in HST-palette

Last night was clear for a long time, I used it to shot
IC443 Supernove remnant. This was a first light for my new Observatory,
POD (Personal observatory Dome).
-
The O-III signal is weak. After some extreme stretching of the data
there was plenty of it after all. I have not noticed before how far it continues
outside of the Hydrogen alpha area. O-III can be now seen at seven a
clock from the main formation and some faint areas in upper left corner with H-alpha.
-
Exposures: -H-alpha 8x1200s binned 1x1
-S-II 4x600s binned 2x2 -O-III 5x600s binned 2x2 Optics: Tokina 300mm TX f2.8 @ f2.8 Camera: QHY9 @ -50 C Guiding: Lx200 GPS 12" + LQHY5 and PHD-Guiding
Grop from the center, not bad details for a 300mm camera lens. IC443 as a natural color version, mixed from narrowband channels. H-alpha 100% + 35%S-II = RED, O-III = GREEN and O-III 100% + 30%H-alpha = BLUE.
A Starless version to show the nebulosity better.
Note an extended Triple Ionized Oxygen outburst in lover left from main feature in middle.

IC443 as a Stereo Pair

Parallel vision version
Cross vision version - -
IC443 with some volume.
The result is more or less an educational guess about real 3D appearance of this formation. - Two versions, first for Parallel Vision , and the second for Cross Vision method. - The original image and the image information can be found here: http://astroanarchy.blogspot.com/2009/02/ic443-in-hst-palette.html

4. Universe Today article


At this time I turned the Hubble Space Telescopes image of V838, in Monocerotis, to the spatial format. -

Distances and shapes in 3D-image are visualizations, since we don't have enough information to buil an accurate model. However, the 3D-model of the target is not only a lucky guess as there is many known "anchor points" in the image, witch can be used to estimate the actual forms and the relative distances.
