Astro Pixel Processor or simply APP has been released on 2 june 2017 and is a fast-growing and complete Deep Sky Image Processing application with several new and innovative features.
APP is being developed by drs. E.M.W.P. Haverkamp (Mabula) who has a drs. and M.Sc. degree in Astrophysics from the University of Utrecht, 2004.
Mabula uses current scientific insights to develop APP besides developing and creating new innovative feautures and algorithms like it’s unique debayer algorithm Adaptive Airy Disc, Local Normalization Correction and fully automatic N-View mosaics.
APP couldn’t have been possible without extensive help and feedback from the astrophotography community worldwide and it’s future development path will be largely dependent on input and support from the community.
September 2019: Astro Pixel Processor and iTelescope.net celebrate a new Partnership !
The following images show how well iTelescope.net and Astro Pixel Processor complement each other. iTelescope.net provides a wide range of telescopes at superb locations to capture beautiful Deep Sky images and Astro Pixel Processor provides all the tools you need to completely process them.

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.

Pelican Nebula Close-up by Sara Wager, APOD 2017-08-03 APOD information:” The prominent ridge of emission featured in this vivid skyscape is designated IC 5067. Part of a larger emission region with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years and follows the curve of the cosmic pelican’s head and neck. Fantastic, dark shapes inhabiting the view are clouds of cool gas and dust sculpted by energetic radiation from young, hot, massive stars. But stars are also forming within the dark shapes. Twin jets emerging from the tip of the long, dark tendril left of center are the telltale signs of an embedded protostar cataloged as Herbig-Haro 555 (HH 555). In fact, other Herbig-Haro objects indicating the presence of protostars are found within the frame. The Pelican Nebula itself, also known as IC 5070, is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus. ” Calibration, registration, normalization, integration and Hydrogen-alpha + Oxygen-III Bi-Color combination done with APP.

M45 – The Pleiades by Syed Taha “The Pleiades, also known as the Seven Sisters and Messier 45, is an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky. The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from their formation, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing. The Pleiades were the seven daughters of the titan Atlas and the sea-nymph Pleione born on Mount Cyllene. They were the sisters of Calypso, Hyas, the Hyades, and the Hesperides. Together with the seven Hyades, they were called the Atlantides, Dodonides, or Nysiades, nursemaids and teachers to the infant Dionysus. They were thought to have been translated to the night sky as a cluster of stars, the Pleiades, and were associated with rain. They were named Maia, Electra, Taygete, Alcyone, Celaeno, Sterope and Merope. The loss of one of the sisters, Merope, in some myths may reflect an astronomical event wherein one of the stars in the Pleiades star cluster disappeared from view by the naked eye.” Equipment: Takahashi FSQ85-EDX Takahashi EDP Flattener 1.01X for FSQ-85EDX QHY268M QHYCFW3-M-US Chroma LRGB filters Pegasus Falcon Rotator Esatto 3” Robotic Microfocuser Tecnosky 70 mm Guidescope & Lodestar X2 Avalon M-Uno Pegasus Ultimate Powerbox Intel NUC Mini PC Acquisition (all @ Gain 0 & Offset 30 in High Gain Mode): L: 125 x 180s = 375 min = 6h15min R: 42 x 180s = 126 min = 2h3min G: 29 x 180s = 87 min = 1h27min B: 39 x 180s = 117 min = 1h57min Taken from my backyard – Bortle 5, SQM 19.75 mag/arcsec^2

Messier 31 – The Andromeda Galaxy Mosaic in 8K resolution by Frank Schmitz, Osenau Observatory – Odenthal, Germany. The mosaic was shot with an 8″ Lacerta Newton, a ZWO ASI 1600 MM pro camera and on a Skywatcher EQ6-R Pro mount. Total exposure time of this LHaRGB mosaic is about 36 hours. “Wow, what a saga that was to put the mosaic together. This is my first LHaRGB mosaic ever and I had quite a hard time to match all the intensities … especially for the color channels. In the end I kept adding subs to low quality panels in order to even things out and zoooom I ended up with 36 hours of integration. My longest integration so far and by far the longest pre and post processing of all of my previous images. Fun fact: My last two images (Melotte 15 and the Pacman Nebula) which were both also 9+ hours were only shot while waiting for M31 to rise 😉 I encourage you to have a look into the full view: NGC 206, Cepheid Var 1, the core, the HA regions, small faint structures in Messier 110 really profit from the high resolution and the exposure time. I hope I did this wonderful target justice and I hope you like it! Let me know what you think!”

The Pleiades star cluster a.k.a. the Seven Sisters (M45), by Jeroen Moonen. Total integration time: 28,5 hours in 256 frames taken is 3 separate periods: december 2016, september and october 2017. Technical details: 65mm Tecnosky Quadruplet APO, 80mm F5 Skywatcher Esprit APO, SBIG-STF8300M with Baader LRGB fitlers. RGB data was shot with 1×1 and 2×2 binning. All four channels have around 7 hours of integration time and are divided in sub exposures times of 300 and 600 seconds. Fully processed in APP.
The Orion Nebula by Steve Milne – LRGB image, shot with a QSI683wsg attached to a Takahashi FSQ106ED and Astrodon Tru-Balance LRGB filters. 14 hours of total exposure time.
“This photo is a 4 panel panorama assembled in Astro-Pixel Processor. Each panel consists of 20X30s images for a total of 40 minutes of integration time. No calibration frame was used. The camera used was a modified Sony A7S and the lens was a Canon 85mm f1.8 stopped down to f4. The Star Adventurer mount was used to track the stars over the duration of the photo capture. This photo was taken from Nakorn Ratchasima province, Thailand under Bortle 3 skies where some light pollution resulted in brightness variations in the sky. There was also a thin layer of high altitude clouds that resulted in the bloated stars you see in this image. APP’s light pollution removal tool helped to remove a good deal of the uneven lighting gradients, leaving a clean region in the image to do final touches on in Lightroom and Photoshop.
