Cygnus 134hour 8-panel Mosaic – André van der Hoeven, Sara Wager, Kees Scherer, Dominique Dierick Qoute by André: ” This image was created in the past year by myself and 3 fellow astrophotographers, Sara Wager, Kees Scherer and Dominique Dierick. It’s a mosaic of 8 panels that I started in 2016 and I’m slowly extending to cover more area. For every panel I try at least to get 5 hours of H-alpha data. Sara, Kees and Dominique were so nice to share their data on this region improving the quality of the image in many ways! The mosaic was generated with the new Astropixelprocessor software which did a great job in processing and mosaicing this image.

This is just the beginning of Astro Pixel Processor, prepare yourself for more documentation to be created, more video tutorials, and an increasing amount of features to be added in the future, to process your data.
image calibration with bias, dark, flat frames and bad pixel maps
accurate star analysis with very high star lokation precision (0,05 pixel for monochrome data) using Intensity Weighted Centroiding.
Registration with Dynamic optical Distortion Correction (DDC)
advanced Data normalization
advanced integration/stack engine including outlier rejection filters and the ability to output rejection, weight and normalization maps.
full drizzle support including bayer drizzle. The drizzle droplet and grid enlargement can be configured. And different drizzle kernels can be used, like point, square, tophat and gauss.
data interpolation algorithms for all different kinds of image transformations like Lanczos and Mitchell-Netravali algorithms.
choose different compositions for you stack before data integration. You can choose to integrate the entire field of view of all frames, or only the field of view of the reference frame, or even a crop of the reference frame.
directly integrate using another scale, so you can directly upscale or downscale the integration result.
the ability to project your data differently than the regular rectilinear projection for huge field of views after camera calibration (focal length, principal point). This is needed for Field Of Views (FOV) larger than 120 degrees.
a very efficient light-pollution/gradient removal tool.
batch tools to rotate, resize, crop, uncrop, and even undebayer(!) your frames
can split your RGB data into separate channels for combination with monochrome channel data.
ability to adjust FITS meta data
the possibility to multiply or divide your data with a certain factor or to add/remove a pedestal to/from your data
preview filter which different automatic stretch settings, background & highlights protected saturation adjustments, contrast increase, sharpening while protecting your stars and the option to reduce the stretch in the highlights, giving tighter stars and less saturated star cores and nebula.
using the preview filter, you can directly save all your results to FITS, TIFF or JPG formats including ICC color profiles for correct color management.
the RGB or Luminosity histogram of your data is always visible
tool for star color calibration
a RGB composite tool with Luminance implementation for the creation of all kinds of composites, like LRGB, LHaRGB, or a Hubble Palette using your narrowband data (SHO).
a selective color tool with the ability to selectively adjust the colors in your images or/and selectively boost saturation and/or luminance.
all data processing in APP can be done on linear data. The selective color tool has no problem for instance with your linear data.
APP will run on any 64bits operating system where the Oracle Java Runtime is available. APP is installed together with the correct Java Runtime Environment (JRE), so the user doesn’t need to worry about this. Currently, complete installers for Linux (DEB & RPM), Windows (.exe) en MacOS (DMG) are available.
Astro Pixel Processor has several features which are unique and innovative for Deep Sky astrophotography:
advanced image registration using true optical distortion correction
the ability to create huge mosaics automatically by solving the registration problem of all mosaic panels as one complete problem
advanced image normalisation using only the data areas that exactly overlap between the reference frame and the frame that needs to be normalised.
a new innovative technique called Local Normalization Correction or LNC. This will greatly improve data normalization in the complete stack before actual data integration.
Multi-Band Blending will remove stack artefacts in regular stacks or seams in a mosaic integration.
a special and unique demosaic algorithm called: Adaptive Airy Disc that will reduce green/magenta cast in your RGB data, will improve sharpness and will make your stars rounder when compared to the well-known AHD and VNG algorithms.
demosaic algorithms for direct processing of monochrome narrow-band data (H-alpha, SII, OIII,…) acquired with One Shot Color (color CCD/CMOS, DSLR) camera’s.
chromatic aberration correction as part of RGB data calibration using a special registration model that will correct all forms of chromatic aberration to a very high degree.
a tool to correct vignetting in your lights/stacks using Kang-Weiss models with or without a geometric factor. The geometric factor is needed for optics consisting of several optical elements.
