This tutorial by Mabula will show and explain you, the very advanced capabilities of Astro Pixel Processor in data registration, normalisation & integration.
DDC = Dynamic Distortion Correction
LNC = Local Normalization Correction
MBB = Multi-Band Blending
We process data of the Rosette Nebula of 5 different astrophotographers:
Irving Pieters: TS Powernewton 8″f2.8, QSI 583wgs
Michael van Doorn C11 Hyperstar3, SXVR-H18
André van der Hoeven C11, QSI 583ws
Rob Musquetier TS 130/910 APO + 0,79x reducer, Atik 383+
Ruud de Vries TS 90/600 APO, Atik one 6.0
Integration time H-alpha : 63000 seconds = 17,5 hour in 96 light frames
All 96 frames proved to be very hard to register correctly in other applications. It’s a rather complex situation because we need optical distortion correction to get accurate registration and 2 data sets of the 5 datasets have flipped data in one of the axes compared to the other 3 datasets. Astro Pixel Processor can handle this with a simple switch. You don’t need to flip the data yourself to be able to register these frames.
You will get an introduction in to when to use the regular or advanced normalization mode.
And 2 integrations are done showing how good and innovative these features are in Astro Pixel Processor.
1) regular normalization mode with LNC and MBB both disabled
2) advanced normalization mode with LNC and MBB both enabled
The difference is really huge 😉 as you’ll see at the end of the video tutorial.
The images shown here are the exact same JPGs created in the tutorial. Be aware that this was only 1 iteration of LNC at the second degree. Increasing the iterations and degrees will only further improve the end results.
This H-alpha layer was used in this hubble (SII H-alpha OIII) composite:
