Baader semi-apo filter
COMBINATION OF "NEODYMIUM MOON AND SKYGLOW" AND "FRINGE KILLER" FILTERS
Customers have repeatedly told us that the combination of our Moon & Sky Brightness filter and fringing remover delivers amazingly color corrected images on inexpensive refractors. Unfortunately, there were also complaints about reflections that occurred with such a combination.
We verified these reports and, as a result, produced a Moon&Skyglow non-reflective combined filter with the Fringe Killer filter coating, with the result that, in fact, a nearly neutral color image is created without the disturbing blue and red fringing. the picture. It contrasts so much with cheap refractors that it degrades.
