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:

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"
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
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.
