5. Universe Today article
A new article by Tammy Plotner in Universe Today:
I turned this Hubble Heritage image of the "Ring Nebula" to the Spatial format.
Cross Vision version

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.

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.

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.

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
A Starless version to show the nebulosity better.Note an extended Triple Ionized Oxygen outburst in lover left from main feature in middle.
