Default Astro: M 97

The 09/10 rainy season in Central California has been less than kind
to astrophotography. It started a month early and seems to want to
continue into May.

I read someplace that on a clear dry night the astronomer is still
observing/imaging through 30 gallons of water. Since mid Septermber
2009, I've been imaging from the bottom of a swimming pool.

This image of M 97 was taken during the only brief period of above
average seeing/transparency since last September.

Bottom of a swimming pool or not that's the best resolution on this one
I've seen in amateur shots. The detail in MCG +09-19-014 is amazing
with the star right on top of it as well. Very nicely done!

I wish I had your seeing.

looks nice to me Glen

count your blessings on the rain: more water in the reservoirs and longer
time until it gets unbearably hot in the central valley/sierra....

we're in Mariposa county near Hornitos. 105F is pretty typical in the
summer...

No SBIG cameras perform well in that heat!

Glen,

great image. The small galaxy to the right shows how good the detail is.

Avoid using Gallium and Mercury for structural parts?
