A set of 10 light frames of Omega Centauri along with flat and bias frames from a Starlight SXV-H9C were collected using a C 11 at f/2 with Hyperstar. Single master flat and bias frames were built during a previous run of auto image set processing by selecting several flat and bias frames on the flat and bias tabs, respectively. After master calibration frames are built they can be used as in this example without rebuilding from the individual files. No dark frames were used becuase of the very low dark noise of the SXV-H9C. But dark frames could be selected on the Dark Frame tab and used for hot pixel reduction with or without dark subtraction. Thanks to Admilson Pinto for supplying the image set.

The goal is to automatically process the set of images and create a single color image ready to enhance.

Step 1

Standard Process tab for OSC CCD light frame processing.






Step 2

Standard OSC CCD light frame processing parameters.






Step 3

Auto image set completed with 8 of the 10 ligth frames since auto star shape grading eliminated 2 images with star size greater than one standard deviation from the average star size. Press the Display Combination button to display the final stacked image created from the best 8 light frames.





Step 4

Auto image set process summary.





Step 5

The 8 aligned images are used as input to Blink Files.





Step 6

The third image is excluded from the set.





Step 7

Stack of 7 calibrated, normalized, and aligned color images of Omega Centauri. The stacked image is often very dark since no brightness increase is applied before display. In this case the 3.9 magnitude cluster is very bright. Detailed processing instructions of the stacked image can be found at OSC CCD Image Enhancement - Omega Centauri
