Here are my sketches from March 1st. Both sketches were through the 10" from a site on the Orange/Red zone border.

I've always viewed M82 at low power with M81 in the FOV, but seeing Howard's spectacular sketch of M82 through a large scope prompted me to try throwing some magnification at the galaxy. At x280 M82 took on a highly lumpy appearance, I think this is what people call "mottling."

This is my first observation of M109, one of the most difficult Messier objects. At x133 I perceived the bright central bar with a possible extension surrounded by a very faint halo. I want to try this one again from a dark site.

Now you're talking! I think you're seeing a bit more than mottling in M82 as that's generally used to describe barely seen non-uniformness. From your sketch it looks like you're seeing real detail.

Your M109 sketch is equally good and I suspect you'll see significantly more from a dark site.

TE,

Excellent observations of M82 and M109. You have captured both very nicely. M82 shows the central bar and mottling well. M109 shows detail as well. Thank you for sharing them with us all.

Carlos
