Re: [APML] Mew M17 image



Thanks Steve and Bert,
 This set of images where the first with my C11 and I was surprised by how long the exposures needed to be.
I was shooting with my 5" refractor and expected the exposures with the C11 to be much shorter. I will definitely
go with a longer exposure next time, with the trees in my yard it will need to wait until next year.
  I also noticed the star ghost on some other images. I was having some problems with my ST-4 running away at the
time and thought that I had sticking relays, but this doesn't look like the same symptoms. I just don't think I
would have bumped the scope on other images on the same night. The color on the raw slide show a dark red nebula,
but I was afraid of pushing it to far.
Thanks, Joe.

Hi Joe:
M17 colors are tough! They seem to vary a lot from person to person. You can check out mine at
http://www.astronomy-images.com/images/Nebulas/m17-Ha-RGB.CCD.htm and you'll see that mine are redder, yours more orange. But if you go to Google/Images and look at a bunch of M17s you'll probably see a very wide variety of shadings.

I was wondering if anyone has an opinion an the colors in my new M17 image? This image was taken with a
C11 SCT @f/6.5 on Kodak E200 slide film, 20 minute exposure.
