M42 + flame arduino tracked

one more attempt testing the arduino tracking.

D7000 with 180mm-f/2.8

30x30s at f/4

stacked with exposit

 

I had to stop taking subs because of the condensation fog onto both

lenses : the tracking webcam+tokina combo, and the dslr lens itself ...

 

Usual amp red-glow at the bottom, I should learn to substract dark frames.

 

And there are several geosynchronous satellites which got invited : the brightest has

it's path dotted all across the frame. notice how tracking errors can be seen as the

trajectory looks like saw teeth.

Done
