THESE STEPS ARE OPTIONAL 1. Equalise all colour channels 2. Seperate with ChannelExtraction 3. Apply ABE or DBE to each image (Start with one with most nebulosity) and then save a 'new instance' and apply this to all channels) 4. Recombine images with Channel Combination *** INSIDE PIXINSIGHT METHDO *** Default Sample Radius - 5 is OK for sampling inside tight star fields, increase this if the stars are further apart. Samples Per Row - No more than 5-7. Minimum Sample Weight - If required, lower this value until all required samples are white. - You can also increase tolerance to turn samples white. LESS IS MORE, DON'T GO FOR TOO MANY SAMPLE POINTS *** LIGHT VORTEX METHOD *** Tolerance - Miniumum 0.5 - 1.0 to 1.5 if too many samples are red Default Sample Radius - 10 to 15 Samples per row - 15 Minimum Sample Weight - 0.1 *** SPECIAL TECHNIQUE *** 1. Download high resolution image of target from 'Digitised Sky Survey'. 2. Register this against my stacked image. 3. Place sample points on downloaded image then apply this to the stacked image. For multiple filters you can create a 'New instance' of this using the blue triangle to drop on the desktop then apply it by dropping them over each opened integrated image to crop them all identically. This process will be each image is identically cropped and therefore still aligned. This is best used for photos with no nebulosity, or perhaps little nebulosity.
