Hello everyone.
I acquired 24 hours of NB data for this target, and used all of it to build a strong background but chose only the very best frames for the object of interest. So I reckon about 15 hours.
Taken with the CDK 17" from Sierra Remote and Apogee U16M/Don Goldman filters.
I hope you like this one.
