New imaging project, the "Pickering's Triangle"



Last night was clear! I managed to get ~5h H-alpha exposures for the "Pickering's Triangle" in the Veil Nebula supernova remnant.
This is a dim target, I'll need additional exposures for this. Together, with S-II and O-III exposures, about 15 more hours is needed for a good signal to noise.

EPIC II









Testing of the theory, part 2
Any phrase looks epic, if placed in front of an astronomical image...


Image used at background is an image shot by me at 2010.
Details can be seen here:



Ps.
I got this idea from Professor Matt McBee, thanks Matt.

IC 1340, project finalized



Finally, after waiting four weeks for a clear night, I was able to finalize this project last night by shooting the missing S-II channel (light from the ionized Sulfur)



IC 1340, Part of the Eastern Veil Nebula in Cygnus
RA: 20h56m 45.8s DE:+31 degrees07' 17"

Image is in mapped colors, from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.

IC 1340 is part of the Veil Nebula, a supernova remnant in constellation Cygnus at distance of about 1470 light years. This is one of the more luminous areas in this SNR. Image is B&W, since it shows only a light emitted by ionized Hydrogen. The shock front formed by the material ejected from giant explosion, the super nova, can be seen in this image.


Orientation
Note. an apparent size of the Moon is at lower Right corner.

The area of interest is shown with a rectangle and the size of the Moon with a circle. 



Image in visual spectrum from the same material

Image is in Natural color palette from the emission of ionized elements, 
R=Hydrogen + Sulfur, G=Oxygen and B=Oxygen + Hydrogen.


Technical details:

Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.

Optics, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO, an active optics unit, and Lodestar guide camera
Image Scale, ~0,8 arc-seconds/pixel
16 x 1200s exposures for H-alpha emission = 5h 20min.
12 x 1200s exposures for O-III, emission of ionized Oxygen = 4h
12 x 1200s exposures for S-II, emission of ionized Sulfur = 4h
Total exposure time 13h 20min.



Ps.

Stars vs starless animation

Soetimes it's easier to see deatils in the nebula, if the stars are removed.
