Happy Halloween
A ghostly figure from deep space, IC 63
Happy Halloween!
I originally shot this target at Halloween night of the year 2010.
I didn't plan to shoot a seasonal theme image, just followed my imaging plan. When the image first time appeared in my screen at Halloween night, I felt cold fingers at my back...
Original image and the imaging data can be seen here:

I want to know
I WANT TO KNOW
I get inspired by a poster, seen in TV-series X-files.
(Mulder's poster hangs in the wall of X-files basement office.)
It turned out, that it was made just for the TV-series by the production team.
Images used in the "I want to know" poster above are shot by me.

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.

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