About this image

Target of opportunity I didn't expect to capture. On holiday, kit limited to leftover space in camper-van. Main target V CVn, but this available, my first attempt at comet polarimetry. Measured polarisation at P= -1.8% +/- 0.5% Errors on the large side, given limitations of equipment. No idea if result in the right ballpark, will have to research a bit more when back in the UK.
