I shot this at the start of the session, before the comet and the moon sank too deep into the murk. This is a one second exposure at ISO 200, Canon 200mm lens at F/2.8. Lots of twilight still, but dark enough to show a good portion of the comet’s tail.
This is 10×4 sec ISO 400 sub-images stacked in IRIS. I had a feeling it would be difficult to process and it was. But, I managed to get this final image regardless.
Here’s one of the first images from the batch of images I shot of Comet Panstarrs on March 11, 2013. I used a 200mm F/2.8 Canon lens with a Sigma 2X Teleconverter, for 400mm of focal length at F/5.6. This was a 1 second exposure @ ISO 400. The camera was riding on an old German Equatorial mount (a CG3 clone) with a clock drive.

Here’s one of the last shots before the comet sank into the murk. I couldn’t even see it anymore with the binoculars, but the camera picked it up with a 10 second exposure.
