Description

Continue testing flattener optimal distance. Colour now added to my previous Ha frame (http://astrob.in/305831/B/). Poor weather did not contribute to the number of frames taken but the new normalisation routines in PixInsight came to the rescue when combining them. Stars show some misalignment since I completely reworked my imaging train/focal distance/orientation, etc.

I'm glad to have captured Sadr in its true colour (spectral type F8) rather than overwhelming the blue channel.
