DBE on Ha image
« on: 2014 January 05 10:13:36 »
Hi,

I have an image of NGC986 that consist of 38* 10 minute exposures. Two stacks that is separately calibrated with bias and flats and stacked. I would like to have some help with DBE. Is it necessary to run DBe ? If so it would be nice with some help with settings.
