Object: Comet 73P
Schwassmann-Wachmann 3
Const.: Corona Borealis - Serpens
Camera: SXV-H9 Scope: Tele Vue NP101 Mount: Losmandy Titan
Filter(s): IR block Exposure: 16x2m
This image of Comet 73P, also known as Schwassmann-Wachmann 3, was acquired using an SXV-H9 CCD camera mounted on a Tele Vue NP101, a 101mm f/5.4 apochromatic refractor. This image is a stack of 16 two-minute exposures that were calibrated, defect-corrected and stacked using AIP4Win Version 2. The exposures were aligned on the comet nucleus during stacking to minimize the blurring of the coma due to the comet's rapid motion across the sky. The image below uses the same source exposures, but aligned on two field stars instead of on the comet. The exposures for these images were acquired between midnight and 12:30AM on the night of April 16-17, 2006.
