The frames for this wide field panel have been acquired and processed by Federico Pelliccia and myself using the itelescope facilities on New Mexico and Australia.

In summary:
- 12x300s Luminance for each of the 3 panels, binning 1x1
- 3x600s Halfa for each of the 3 panels, binning 1x1
- (1,1,1)x300s RGB for each of the 3 panels, binning 2x2

Note: on IC434 we did a short session with the TEL T7 0.43-m f/6.8 astrograph and the TEL T11 0.50-m f/6.8 astrograph.

Processing: PixInsight, PSCS5.
