Minimises unwanted blue fringing in achromatic refractors
Discover your refractor anew using the BAADER Fringe-Killer Filter which minimises unwanted blue fringing, comparable to a Minus-Violet-Filter, while retaining a very pleasing colour balance (a very important factor). This would be a contradiction in itself only made possible by applying modern DWDM plasma assisted coating technology,allowing almost a hundred coating layers to be accumulated onto a planoptically polished substrate without destroying the optical figure!
This fine optical tool will help a small refractor to really put the advertised magnification within reach. Performance rivals that of the most expensive color correcting lens systems, costing 20 times as much!
