You may simply choose the Analyze -- Photometry option and then click on the stars you want to analyze.
(Caution: Try not to Zoom. Un-zooming seems to be a problem and may cause you to restart the entire process!)
Your results are recorded and can be saved as a text file. You can also click on individual data lines in the read out window and it will highlight the star previously selected. The readout lists intensity (this would be the amount of light measured from the star) and sky (this should be subtracted from the intensity.)
First, choose your images from Skynet so that you have an image in each of 3 colors. B (Blue), V (Green) and R(Red) are preferred but not essential. You just need three different wavelengths. The file name of each image should hold a clue as to which image is which color.
Now Use SalsaJ
Open SalsaJ
Then Open--File and select your "red" image.
Convert this image to 16 bit by choosing Image--Type--16bit
Finally color this image red by selecting Image--Lookup--Red
(You can adjust this amount of red by going to Image--Adjust--Color.)
REPEAT these steps until you have a V and a B image colorized...THEN
Image--Stack--Image to Stack
Image--Color--Convert stack to RGB
VOILA!!
If it has a rainbow effect, the images need to be aligned so...go to
Plugins--Align RGB
Ah! Better:)
NOW 2 things!
(1) Save as to a JPG in your file area. (Making a screen shot using the "Snip tool" (pc) is better.)
(2) Print (and select a color printer!)
