Antlia 2″ 4.5nm SHO Filter Set
Antlia made huge efforts to minimise halos around bright stars and achieved very good results with the Antlia 2″ 4.5nm SHO Filter Set, therefore you will most likely never see halos, however this is a very complicated topic as halos can be caused by various elements in the optical train. There are thousands of possible scenarios and they simply cannot promise that there will be no case when some level of haloing will appear. Antlia filters are extremely good and represent very good value, but only much more expensive filters (like Astrodon and Chroma) are likely to provide halo-free images. We can supply these filters, however in most cases Antlia filters offer a near-perfect solution at an affordable price.
