Two new PixInsight processing tutorials have been added. The first one is on producing an HDR image and the second one is on enhancing broadband LRGB data with narrowband data such as that from Hydrogen-Alpha and Oxygen-III.
The first tutorial goes over the procedure to produce an HDR image out of multiple images stacked from exposures captured with different lengths. This technique is particularly useful for targets such as M42 Orion Nebula and M31 Andromeda Galaxy, reproducing detail across bright and faint regions all the same. The processes used are HDRComposition and HDRMultiscaleTransform. The procedure described applies as equally to monochrome images (LRGB or narrowband) as to One Shot Colour images.

The second tutorial goes over Vicent Peris' official method using the PixelMath process to combine broadband LRGB data with narrowband data such as that from Hydrogen-Alpha and Oxygen-III. The combinations discussed are enhancing the Red channel with Hydrogen-Alpha, enhancing the Green and Blue channels with Oxygen-III and finally, enhancing Luminance with Hydrogen-Alpha.
