Solar activity 2013 May 1 (Italy)

[Ciarlotto (Nunzio)]

Hi everyone,
yesterday yhe seeing was 6/10 and transparency 7/10, so I spent my time in performing my practice for solar imaging. It's my third work with Mak 127 + ASI120MM + Baader Continuum and IR/UV/cut...
I mainly used the Mak both at 1500mm and 2250 focal lenght: I think it's the best focal lenght's range to work by using this set-up when the seeing is not excellent... ASI camera has little pixels (3,75micron) and it help in easily reaching the optimal sampling ( by simple calculations, it should be 1600-2200mm). I tried to capture at 3000mm focal lenght too, but I was not completely satisfacted by the result I achieved: the seeing got worse and details were mostly confused...

1500mm focal lenght:

An impressive set Nunzio – I enjoyed the progression through the increasing focal lengths used. The last 3000mm http link did not work for me.

Cheers

Thank you Dennis.
The link has been corrected...

Very nice! Love the granulation in the 3000mm shots.
