I followed the directions that were in the pdf that was sent. First, I downloaded the plugin from the linked website. Then I downloaded the folder NCG 7023 from the NOAO website. Then I followed the rest of the instructions for using Image J. My composite image adjusted to what I thought looked the best. Compared with images of this object from the web, my image was more green in hue.
I completed the tasks from module 10 by simply following the directions from teh pdf. It took a while for the plugin to become active...so I used an old method to combine the images. After the plugin took effect, I was able to manipulate the images with the composer tool. I liked using the tool to align my images. I would zoom in on a star and use the arrow keys to adjust the central portion. One thing that was a little tricky to remember was making sure that the images were in the right filters and clicking update to make the change. At first, one of my images was too blue. I revised it and when I compared it to what I had initially created, my second image was more "white".
From Shannon Aaarrgghhh...so many questions and tech problems on my end. I just don't always know what I'm doing...So, I'm supposed to talk about how I constructed the images with adjusting, color combining and aligning. It's taken me DAYS just to be able to open the images (user error, I'm sure). Once I got them open and was able to follow the directions to get the best pictures of 3 images, the RGB composer did most of the work. I didn't have to do much aligning (it was pretty good when it popped up) and wasn't too sure what I was doing with the color. I played around with it until the image looked pretty clear. I was suprised when the R image showed the gas (?) cloud. Very cool!! So, why doesn't it show on the B and V image? Or, I messed up and it was there and I didn't find it? Dunno, but this took me a long time to complete and many whining emails to Chris.
