Description

I have been revisiting my AP technique and wanted to make sure I was doing all I could to maximise the opportunities, given the poor weather in the UK. To this end I have been following the excellent Maxim DL tutorials by John Blackwell on YouTube, in particular calibration of raw images and LRGB stacking. I am now taking flats with an electroluminescent panel as well as binning RGB data. Last night was a good night to try out what I have learned. 6x300s L, 6 each of RGB x100s binned 2x2. Anybody going to the Southwest Astro Fair in Sidmouth next month? See you there!
