Thanksgiving Clear Sky

New image: The Flaming star nebula, IC 405. Taken November 23, Thanksgiving night, from Clearfield Observatory.

The sky was very clear Thanksgiving night as an approaching low pressure system was pulling dry air over my area. This is one of the longer exposures I have done with over 35 individual exposures taken that night.

This picture was done with the telescope at f4.5 using the Astro-Physics .75 telecompressor. In the past I have not used this configuration as much because the vignetting from the two inch camera adapter is significantly greater than the f6 field flattener configuration. This leads to problems when processing the final photograph. But with my light box I can take flat field frames that corrects this problem. I should have been doing this all along as this has increased my photographic options with only a small amount of additional work.
