Above is quite a wide-area shot of the Christmas Tree Cluster and Fox Fur Nebula area. Note Hubble's Variable Nebula just below center towards the left edge of the frame!
This is from Wimberley in March 2014, consisting of 43 frames of 5 minutes each (just over 3.5 hours) using the SBIG ST-8300 Monochrome CCD Camera with a h-alpha narrowband filter plus the Takahashi FSQ-85 "Baby Q" telescope with reducer. Conditions were not great during either of the two nights of imaging. Check out the sky and cloud action in the time lapse video from the second night on my time lapse video page.
The Christmas Tree Cluster is NGC 2264. The "cone" part is on the left part of the image, just below center. This includes the "Fox Fur Nebula".
IC 2169 is in the area.
Above Image: 16 * 5 min = 80 minutes total exposures. Takahashi TOA 130 Telescope (a 5" APO refractor telescope) with the flattener, AP 900GTO mount, QHY8 CCD Camera. Other pictures from the camera are are here. Images processed using my Astronomy Image Processing Workflow. Compare with my older DSLR image below.
Other Images from Oct 2008 Davis Mountains are here. The 2008 "Holiday Version" is at the bottom of this page.
The Christmas Tree Cluster is NGC 2264. The "cone" part is on the left part of the image, just below center. This includes the "Fox Fur Nebula". SEDS info here. Also some good info here.
Image and processing notes: In 2008 I note the image above looks a little rough in parts of the nebula. This is another very dim object and I didn't have enough exposure to overcome the noise in the dimmer areas. It's represents an early processing effort and I could probably do a little better today. Combination of 8x4 minute exposures (32 minutes total exposure - I originally had 13*4 exposures listed, but reviewing it looks like it was 8). This area is very dim and I could use more exposure time. I did 3 applications of Neat Image noise reduction, as well as a selective Gaussian blur to help tame the noise. Takahashi TOA 130 (a 5" APO refractor) and Canon EOS D20a. This is resized to be about 30% of the original's size. My current image processing workflow is here.
Temperature ranged from ~51 degrees F at the start of imaging to 42 degrees when I was packing up and doing my last darks.
Christmas Tree area - my best effort with the Nikon D100 - a major challenge with the due to weak red response of this camera.
