A practical demonstration of DSLR astroimage assembly with some processing
This talk will be geared toward people who have tried using DSLR for astroimaging but would like to learn how to get a little bit more out of their hard-earned exposures. Over years I used to talk about image calibration at NEAF, MAAW and AHSP but this time I would like to present something more practical – so do not expect nice images, because, in a sense, uglier are the better for this purpose . Topics will include image acquisition, camera characteristics, dealing with dark current and flat-fielding, Bayer-array decomposition, registering and stacking, narrowband imaging, color assembly and balance, basic scaling, creating mosaics. While IRIS and AIP4WIN will be used for demonstration on sample deep-sky DSLR images, the general approach will be software-independent.
