Hmm... then any idea what cause those "strange effect" surround most of the stars??
Have a nice day.
Is it due to the compression into JPEG?
[80% Steve, 20% Alfred] ------- Probability of Clear Skies = (Age of newest equipment in days) / [(Number of observers) * (Total Aperture of all telescopes present in mm)]
this is a compression artifact typical of JPEGS saved in low quality mode. Try a higher quality instead. It might be possible due to excessive iterations in the LR decon process but this will normally give rise to halos that are less abrupt and sharp.
