ASTRO: NGC4565

Taken from a farm just south of Blueknob State Park on 21 March
2009. Taken with an 6 inch refractor at F/7.3. Three 20 minute
exposures using a Hutech modified Canon 40D at 200ASA.
Cropped image, reduced 50%.

That is one sweet image! I doubt that 200ASA film could do the same with
equivalent exposure.

Nice to see your great DSLR shots back again. Due to heavy reciprocity
failure of color film I'm sure your ASA 200 is far faster than what film
would give over 20 minutes time. I used to use it and boy even 400
with hypering wouldn't do that well for me anyway.

This also reminds me I've never done color for this galaxy. If my
clouds ever go away (before the moon shows up) I'll have to try and get
some. I seem to have left the big guys for small ones of late.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Very nice picture Robert. Out of curiosity, which refractor did you use?
