OK I just finished processing the image for today, this is the best 52 images stacked using the 350D set at ISO 100 and each exposure 1/1250 sec + Takahashi E160 astrograph (with a 40cm long dew shield to keep sunlight at bay). As you can see obvious brightening from yesterday and the beginning of the tail is now visible. Brightness is conservatively mag -0.5 from comparision with Venus. Nearly missed the comet as it was at the top edge of the field (my RA setting circle is pretty crude!).
