Re: [APML] M3 in Canes Venatici

Nice shot, Chris, both the depth of the exposures and the color balance.
That's just how I would like my film attempts to come out, but as you note,
the CCD has the dynamic range advantage here, hands down.

I have three shots of the object still on an almost-finished E200 roll, at
10, 15, and 20 minutes @F/10 with a 12" SCT, and I'm curious to see how
they've come out.

I really wanted to not burn out the core but show some of the outer
stars--I 'm looking for almost the same presentation that you've captured,
but I suspect my exposure times are probably on the under side.

I'll make one or two more at 30 and 45 minutes, but you're correct--it is a
very bright object relative to most DSOs we image, and it's easy to
overexpose the core and miss much of the aesthtics of the object.

Hi All,

here is my new shot of M3, a rather bright globular in CVn.  I rather like
the blue and gold colors of this one,  what do you think?
