This three section mosaic image contains Barnard's Loop , NGC2024 the Flame Nebula and Horsehead Nebula, IC434 . B33 and M78 .
I took these images on two separate evenings under bright moon light sky conditions with stars only visible down to magnitude 4.5. I was using a 200mm lens piggybacked on my ten inch reflector mounted on a VIxen Atlux mount.
I was also using PHD auto guiding, a set of Astronomik narrowband filters. A HA filter, an O111 filter. and a blue with an Atik 383L mono CCD camera .
I captured five minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image .
The total exposure time was 90 minutes using a HA filter 15 minutes using an O111 filter and 10 minutes using a blue filter.
