Horsehead Nebula

Stargazing Live from my own back garden this evening. My telescope & camera pointing towards the heavens to image the amazing Horsehead Nebula.

The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming.
1 hour only of exposure Approx 40 mins @ Iso 3200 and 20 Mins @Iso 1600 using 2 minute guided sub frames. My collection of darks are proving useful with a dark frame subtraction. DDP and levels adjustment and aquisition provided from images plus and Deep sky stacker combining the frames.

M42




The last week or so has left us all a bit battered by the winds.
The moons phase equally annoying for a deep sky imager. I wanted to just test everything was still working as it has been over a month since rolling back the dome roof. Last year I was able to test my UHC filter on ngc7000 on a series with and without. So last night I pointed towards Orion and done a series of 3 minute images at Iso 800. I love the colour rendition that the filter gives. A more natural look from unfiltered. M42  I think. Just wish we were a few light years closer!!!!!!!
