Unfiltered image of comet P/2010 H2 (Vales), obtained by Ernesto Guido & Giovanni Sostero on April 16.42 with 0.25m, f3.4 reflector.
Image was stacked with 6 unfiltered images of 120-second exposure. It shows
that this object has an FWHM consistently wider than the nearby field stars of similar brightness.
An additional stacking of 6 unfiltered exposures, 30-sec each, obtained through the same instrumentation
on 2010 Apr. 16.43, confirm this evidence. Copyright © 2010 by Ernesto Guido & Giovanni Sostero.

Images below were taken by Alain Maury on April 17 with C14 f1.96 (hyperstar focus), QHY9 unfiltered camera, 1.6" per pixel scale.
He stacked 60 images, each with 60 second exposures. Here is an image of the object, stack recentered on the object. Copyright © 2010 by Alain Maury.

Image with a very high contrast rendition. I can clearly state that there is a faint coma around the object.
The coma is about 50 pixels large, therefore about 1.3 arc minute wide.
