IC434 HaLRGB
IC434 Hydrogen alpha filtered

The data was downloaded from here https://www.roboscopes.com/ , a robotic observatory located in Spain with Bortle 2/3 skies.

The data comprised Ha 20x600s, R 12x900s, G 9x900s, B 12x900s, 20 darks, 20 bias and 10 flats for each filter.  Equipment was a Takahashi FSQ106ED and QSI 683ws CCD camera.

A synthetic luminance frame was created using the tutorial here (thanks Diego):

https://www.astropixelprocessor.com/hargb-tutorial-by-diego-colonnello/

The data was processed as Session 1 RGB and Session 2 Ha.  All defaults were used with the following additions:

  • Create Bad Pixel Map (calibration)
  • DDC enabled (registration)
  • 1st degree LNC selected (integration)
  • MBB enabled (integration)

The Ha, R, G and B stacks were combined to create a synthetic L frame.

The R, G, B , L & Ha stacks were combined, with the following slider adjustments made:

  • R  X -> 1.5
  • R  R -> 100%
  • L  X -> 1.5
  • Ha  X -> 1.5
  • Ha R -> 100%

I have included the processed Ha stack.

Thanks to Brian (@oopfan) for his help & suggestions with processing.

Very nice Dave, the first one seems a bit uneven in the background. Did you use LP correction in APP?

Thanks Vincent.  I had  another go at the LP correction and framing after a couple of watches of the new Christian Sasse video.  This is an area of processing that I am not yet comfortable with.  I will keep working on it.
