Matt,

I did use registars' average function.  There is a "max" option, which takes
the brightest pixel, that helps the signal a bit.
But it doesn't help the noise/grain as much.
The 70min showed significantly more detail than the
30min.  So..tonight (if skies hold up) I'm going to try 90-100mins.

 >What's the LVM there?

5 in that area of the sky.  About 5.5 straight overhead.

 >The film wasn't hypered?  Looks like Supra 400's a pretty good film.

No..not hypered.  And yes.. I really like the supra.  And although
I don't have many galaxy shots to compare with, I was happy with
its performance on leo's trio.

 >You still need that field flattener.

Rub it in why don't you!  Funds just aren't there right now.
PS 6 and my new guide scope emptied me out.

What do you think of the corners? I worked hard on the av / color
correction layers.  Image is full frame with no cropping.
