My take on two winter classics

Hello all,

Here is my take on two winter staples. The first is the Horsehead nebula (had enough of this yet? smile ). This is only my second attempt at this nebula, and only my first LRGB.

Takahashi TOA-130F on an Astro-Physics AP1200GTO mount. SBIG STL-6303E camera with FW8-STL filter wheel and Astrodon LRGB and narrowband filters. Robofocus focuser and Astrodon Takometer rotator.

H-alpha: 11 x 30 Minutes Binned 1x1
L: 24 x 5 Minutes Binned 1 x 1
Red: 18 x 5 Minutes Binned 1x1
Green: 18 x 5 Minutes Binned 1x1
Blue: 18 x 5 Minutes Binned 1x1

12 Hours Total Exposure Time

Small version attached. More details and links to larger versions at my web site:

Next up is the Cone and FoxFur region (which seems pretty popular these days). This is only my first try at this region! I'm pretty please with the way this one turned out in various combinations of H-alpha/LRGB, that I had to post all my variations.

Same equipment as Horsehead.

H-alpha: 10 x 30 Minutes Binned 1x1
L :16 x 10 Minutes Binned 1 x 1
Red: 17 x 10 Minutes Binned 1x1
Green: 17 x 10 Minutes Binned 1x1
Blue: 17 x 10 Minutes Binned 1x1

16 Hours and 10 Minutes Total Exposure Time

LRGB preview attached, other combinations can be seen here:

Enjoy,

I especially like how the reflection right below the horsehead stands out. This is really a challenging region with that bright thing in the middle.
