Remember it is not necessary (or practical) to manually deselect the low quality frames from your sequence. Registax has built-in features that will automatically filter out low quality images based on individual frame quality and alignment differences. However, viewing the frame list will allow you the ability to scroll through and select a high quality, high contrast image to compare and align with all the other frames in the sequence (See Aligning Screen in next section). 10. Frames-slider (control) - This allows the user to walk through the images and select/deselect them (using the spacebar). The functionality overlaps slightly with #9. 11. Project load (button) - This allows you to restore previously saved settings and image-information. After loading, the program will bring you back to the stage where you left. You can load project-files and also frame lists (saved previously from the frame list) with this function. 12. Save (button) - This function allows you to save most of the current settings of the program and also the information needed to process your images. If you have aligned your images, that information will be saved. If you have stacked your images it will also know that. This function allows you to stop working on a set of images and continue your work later without loosing all the information of alignment, etc. The files used are simple ASCII-formatted files and are saved as *.rsp (RegiStax Projectfile) 13. Save as (button) - You can save the current settings of the program as a "logical" file name. The program will show the date_time the avi-file was shot in the following format (_yyyymmdd_hhmmss). You can alter this name (add a subject name in front of date/time) and save the project. A projectfile will be created with this name and your original avi will also be assigned this name. This makes it easier to convert your recorded avi's into logical named ones and keep track of them. 14. Help (button) - This provides a simple help text that shows some of the default functionality of the tab page that is currently active. The texts are in a set of 5 rtf files the user can enhance themselves. 15. Cancel (button) - This button can be used at any stage to stop processing. Sometimes this will not lead to an immediate halt of a processing run, and the use may need to wait until the last command has been executed. 16. Load Darkframe - Pressing this opens a dialog where the user can select a darkframe (bmp, fits) to use in processing. For certain astro-images it is usefull to use a darkframe to remove "hot" pixels or a flatfield to reduce vignetting effects. You can choose a BMP or a FITS file to serve as darkframe/flatfield. The program allows you to create darkframes/flatfield directly from a sequence of images. Just load the sequence and press the "Make Darkframe" or "Make flatfield" button. When a darkframe/flatfield is chosen you can decide to use it by checkmarking the corresponding checkbox. Make sure your darkframe and/or flatfield are the same size as the input images! 16
