Oh that dirty dust........

[Cottonwood]

I had forgotten about it after even seeing it in several images and I had begun the task of cloning out the dust etc. Well after making many solid attempts at cleaning the particles of dust off the sensor, I fired off some test shots of the sky..... still dust on the sensor.

A bit of research at this link http://www.tribcsp.com/~sigma2/SensorDust01.html

I followed this to the letter

See this attached photo of before and after results
