SPX350 F31.5, Flea3, 5xPowermate, Astrodon filters.
Nice and clear with some mist before midnight which cleared, collimated on Spica as usual and used a slightly longer fl at 11,035mm but only managed an hour before cloud rolled in. Seeing was so promising with hardly any Spica twinkling with Saturn at 40 deg alt and seeing at 8/10 looking like a great night with Saturn just vibrating in focus for few seconds at a time.
Managed only 3 red channels 20min spacing and seem to get same shadows in the rings on the left much clearer with 20mins spacing. Only managed 2 rgb's but storm showed quite a bit of detail.
Experimented with gamma which I don't normally like but it does enhance the Crepe ring somewhat and the IR looked better with stronger banding visible with a light spot on the pole, the second IR without gamma had similar light spot?
Image1 - r rgb.
Image3 - ir 742nm with gamma 1300.
Image3 - Gif 3 red channels forward and back.
It was so hot last night sweat was pooring of my face and felt quite sick, this is my first summer in Oz and its not even hot.
Got 5 clear nights in a row with Saturn and now there are 2 Cyclones bearing down on QLD - Oh dear!!!
Thanks, John.
