About this image

Unexpected early evening clear sky. The outburst is impressive even in Moon-light, and well placed near Vega. Track-and-Stack with Astrometrica with post processing in AstoArt.

The camera has a GPS receiver built in, so frame timing is to 10ms accuracy (if required). GOTOs are executed from SkyMapPro to EQ8 (EQMOD). Sharpcap Pro controls the camera (and mount) and i have set-up plate-solving. This adds accurate RA/DEC to the FITS Frames. Astrometrica uses the FITS header to get the frame center for solving and track-in-stack. The software takes the comet motion and PA from MPCORB. I use the UCAC4 star catalogue on the hard-drive, but Gaia is also available.
