Processing Using Nebulosity v1.5.1 Example 1: Cygnus @ 50mm The constellation Cygnus was shot on a clear night using a Canon 400D (unmodified), a Sigma 28-80mm zoom lens @ f/5, and an Orion Broadband light pollution filter. 18 frames of 2 minutes each were shot at ISO 1600. 5 dark and 5 flat frames were converted to Fits, then averaged to a master dark and a master flat. Each stack of light frames was processed thus: 1. Batch conversion Canon Raw to Fits. 2. Pre-Processing was applied. Darks were auto-scaled. Pixel Map sensitivity was default. 4. Batch demosaic was done. 4. Translate and Rotate with Adaptive Scale Stack to 16 bits. 5. Files were saved as 16-bit Tiffs. 6. Files opened in Photoshop CS. Three Curves functions were applied to make images visible: Input level 20, output level 50.
