Vgood seeing to start but had to wait for Saturn to rise to 60+deg alt, got a nice diffraction ring around star Spica during collimation for first time ever in 2 years of planetary imaging so looked good for the night.
The 3 R RGB images 1245/1310/1340hrs UT, only decent IR was during 1245hrs set. I find IR only useful with Vgood seeing.
Saw storm patch in the South quite strongly for first time and picked up intricate detail in North storm track away from storm head.
Mirror misted and image faded with wobbly seeing I think due to primary fan which was on as I have foam nose on end of scope so fan may have cooled top end drawing cold air through, but don't really need fan just a habit?
Thanks for looking, John.
