Forums Comets C/2017 K2 (PANSTARRS) Near prediction

Grant Privett

An image of C/2017 k2 at mag 18.9 and 15.9AU from the Sun. As seen through thin cloud (was supposed to be clear but clouded while I was setting up – not exactly uncommon round here) with a 10″ RC and Trius 694 camera.

I additive stacked 120s exposures tracked at star rate only. The variable transparency would have played hell with a median stack.

The position is close to the prediction in RA but – if is right – not quite right in Dec. My SNR was too poor for a clearer assessment.

The frames need to be aligned on the comets motion for a better result.
