I like the wide angle shot a lot. You have managed to capture the horsehead with good contrast and still tamed the bright star very well. Congratulations on this nice work.
As the horse head gets more and more close ups, it looks less and less like a horsehead to me. I think it was a better horsehead when I was a child. (G)

Subject: [digital_astro] Another Horsehead Nebula!
This was a 2-night affair with good transparency both nights.
It was taken with a Takahashi FSQ-106 at F5 & F8 and a Canon 10D at
ISO 1600 piggybacked on a pier mounted 12" LX200 located at Yanna
Research Station the dark sky site of the Madison Astronomical
Society.
It consisted of 20-4min exposures at F5,15-5min exposures at F8 and 6
Median combined darks. The 15-F5 exposures were untracked and the F8
images were tracked with a STV Deluxe.
All F5 images were converted, calibrated (median), aligned and
combined (averaged) and initially stretched using Digital
Development. A mask was then used to brighten the red outlying
regions and blurred and added to the original image, all done in
Images Plus. The list goes on.
The F8 images were converted, calibrated (median), aligned and
combined (averaged) and initially stretched using Digital Development
resized in Photoshop before combining them to the F5 images with a
mask.
This image took 3-4 days to process to get the result I was looking
for. Allot of experimenting with different filters, stretches and
sharpening techniques.
All in all I was very pleased with the result.
