14 AUTOSTAR CCD PHOTOMETRY
11. Select Start. (Fig. 2-17.)
Figure 2-17. Start Button.
12. After at least 10 images have been combined, select Stop. If
longer exposure times are used, a lesser number can be stacked.
Only images meeting the Min Quality % will be included in the
combined stack. If the seeing is poor, it may take several minutes
to get 10 good images, even with exposures of just a few seconds.
13. Repeat Steps 11 and 12 two more times to produce a set of
three stacked image files. This will allow the data to be averaged
during the analysis process (described later).
Note: If a failure occurs during imaging, the seeing turns bad, or
for some reason not enough images are stacked, just run an
additional set.
14. Select the V filter and repeat Steps 1 - 13. Name the file(s)
“Star Name”-V-“Time”-1- etc.
15. Select the R filter and repeat Steps 1 - 13. Name the file(s)
“Star Name”-R-“Time”-1- etc.
16. Select the I filter and repeat Steps 1 - 13. Name the file(s)
“Star Name”-I-“Time”-1- etc.
Note: You should now have three combined/stacked image files
for each filter (a total of 12 image files). When the image data sets
for each filter are averaged, one data point for each filter will be
produced.
