Description

Second attempt at the Horsehead Nebula. The first time, the dew heater plug was pulled out of the power source and dew collected on the corrector lens.

Calibration was done using AstroImageJ. However, because of tracking issues, I could not align the images for stacking, so I used SIRIL which isn't as picky as AstroImageJ. Then I stacked the aligned images with SIRIL as well. Post-processing was done in GIMP.
