Ektachrome E100 on M8

A look at the new Ektachrome 100 on an astronomy target.

Tracking has some issues. This indicates problems that will need to be resolved before trying a deeper exposure.


The good news is that this film shows strong sensitivity to Ha. The reflection nebula of the Trifid shows that the blue sensitivity is lacking. This could also be from the use of the light pollution filter.


Surprising amount of stars recorded with a 20 minute exposure.
