Comet Lovejoy and Orion

Last night (10th January) the skies were reasonably clear at times so I obtained a few images. This time I used the 100mm Zeiss lens at f2, reduced the iso to 800 and increased the exposures to 50 seconds. The resulting images were very nice in Lightroom, but the lens suffers considerably from vignetting. The Adobe profiles are not ideal with long exposure astro photography so I produced a few flat files and used Deep Sky Stacker  to generate a Tiff file for subsequent processing. The results are not perfect but its a bit better.
