Indeed! Spring is galaxy season - especially (for visual observers) when there isn't a bright moon in the sky.

Your M101 image shows an impressive range of brightness levels without overly drowning out structures near the core.

An attempt at humor: It really does look like giant black holes reside at the centers of most galaxies! :-)

Sketcher,
To sketch is see.

Bad weather is finally over, and the skies have cleared here in the Midwest.

This large galaxy, M101, has a huge brightness range, which makes it a challenge to process. I once saw a Palomar glass plate of this object which showed the huge range quite well, because negative film has a non-linear response at the very bright end.

I posted this shot that I did last night as a negative. It shows the very faint extensions better than a normal image. It also brings back memories of the old film days before CCDs. Note the numerous tiny background galaxies.
