$RB-60 Refracting Telescope - Meade$

Once the star reaches the first target position the yellow cross will move to the lower right corner. The target position will move to the next position each time the selected star reaches it. The next position is the lower left corner and the last position is the upper left corner. Once the star reaches the last position imaging will stop. But the telescope will continue to track on the last position. During imaging you can change the target position by pressing the “Set Target” button and then clicking on the desired target position on the live image. 8. Final Stretch Once the image is complete you can touch up the histogram stretch and shadow enhance settings and then save the final result by selecting File->Save from the menu. Drizzle Tutorial #2 This tutorial demonstrates how to use Drizzle after you have already captured images and are working off-line. Offline Processing A new feature is the ability to run your captured images back through the Drizzle process. Bring up the program without the imager plugged in (to lighten the load of the processing power of your computer). You will then see the “Image Files” tab on the top. 1. Add images Drizzle Tutorials 3 Press the Add button in the Image Files tab on the top. The familiar Open dialog will appear. Navigate to the directory where the images are. Select the first image of the sequence and then scroll to the last image. Hold the shift key down and click on the last image. All the file names from the first to the last should be selected. Now press Open. After a few seconds the files should appear in the “file name” list box. 42
2. Select images Select the first image in the list and after a few seconds it should appear in the live display. You can use the arrow keys and go up an down the list and the image will appear. Inspect each image and click on the Remove button to take the bad images out of the list. This will not delete the image from your hard drive. 3. File Type: [what ever you want your final image type to be] This setting is up to you. The FITS file types will save the full dynamic range but the others formats may be more user friendly. 4. Save Options: Normal This is the only setting that is valid, the other settings are ignored. 5. Select “Drizzle” from the “Image Process” dropdown menu. 6. Enter a name in the Object Name box. 7. Set Min Quality and Evaluation Count to 0 and 1 respectively. Select these settings so that every image will be used in the final composite image. This is acceptable because you have eliminated all the bad images in a prior step. 8. Press the Settings button. See the Drizzle Resolutions section and the sections following it for a description of these settings. These settings can be experimented with each time you re-run the process. 9. Select 2 stars.
