Default Cosmic Pollywogs in Hydrogen Alpha

All,

First attempt at imaging this and it turns out to be a most interesting
object. IC410 in Auriga. 3x30 minute sub exposures Sigma-Reject Combined
and levels and curves in Photoshop. Not centered in the FOV but there
were no guidestars to be had visible through the Ha filter.

Needs more data though and I'll certainly gather some more when the
"grey nebula" clears.

Comments welcomed.

Regards

Bill

I just added a link to this picture in my article about observing IC
410 and the tadpoles -- which so far I've not been able to verify by
eye, looking at the nebula (I wonder if it can be done? Might
possibly require a very, very large aperture scope...)

The other pictures I had used as references were all done by larger
aperture Ritcheys. You have achieved virtually the same clarity with
a smaller scope having more conventional optics: congrats!
