2019 September: Astro Pixel Processor and iTelescope.net celebrate a new Partnership!
IC434 HaLRGB remote data
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):
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.
Oh excellent! I think this version is a lot better already. Nice. 🙂
