Tomas,

Those inset images of the comet coma sure do show some strange details, I am surprised that with images of 75 and 60 minutes that the spike look didnt wash out. Do you think that is an artifact of a Newtonian telescope or what the coma actually looks like? I have never used a Newtonian so that is why I ask. Very well done.
