A shooting star into NGC6910 and NGC6914 field.
From a single subframe taken by Canon EOS550d with CLS clip filter on William Optics Zenithstar 61, ISO400 600sec, while recording focused on NGC6910 available on sky from my balcony in the first part of the night.
To process this singular frame I made 3 copies and calibrated with dark/flat/BIAS once using normal BIAS integration, then using SUPERBIAS integration and calibration, thus to get 6 files to process with their drizzle data.
