12P/Pons-Brooks 2023-Jul-27 Gianluca Masi

The images above come from the median combination of 29, 180-second unfiltered exposures, plus some additional processing and were remotely taken with the Celestron C14+Paramount ME+SBIG ST8-XME robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy. Images were collected under good seeing conditions.

On the panel above we can see: the master image (upper left); a 15 deg. Larson-Sekanina rotational gradient (upper right); unsharp masking (bottom right); Richardson-Lucy deconvolution (bottom justify).
