  1. Even if you can not see it with your eyes, it is always worth pointing the camera in the right direction and taking a few snaps. As i found out the other week i could not see the aurora, but the camera could 🙂 The visibility only lasted around an hour that night, but i caught the tale end of it for the first time from Bedfordshire.

    While not the same as seeing it with the naked eye, it was still pleasing to capture it from this far south.

  2. very enjoyable thread to read, love reading all the different views regarding FL and optimum imaging scales. Something i have "wrestled" with for years, without truly having a definitive answer 🙂 

    In answer to question of  focus though i always focus on the planet. I stand back from the monitor and watch the planet for making tweaks as the seeing inevitably comes and goes. You going get plenty of out of focus frames most nights, hence its called lucky imaging. A term i dislike, because there is very little involved when you look at some of the images produced by planetary imagers around the world.

    One of its best tools is frequency domain filter which removes noise without blurring or smearing.

    Hope you don't mind but I've put one of your images throught IA and removed some noise with FDF. Also auto adjusted white balance and removed colour noise.  Gives you an idea of what can be done In IA.

    Any tips regarding the settings for frequency domain filter you used Stuart?
