Filters

We did also try UHC and OIII filters just to see what they would do. To me, the results ranged between inconclusive, unsatisfactory and unaesthetic. I was unable to replicate what others on the net had reported, with Antares A supposedly showing a deep red colour in an OIII. It looked utterly green to me. The B component was seen, but it just didn't look good. A UHC seems a complete waste of time, because it produces double images that happen to be of similar colours to what you'd expect to see from Antares A&B. Unpleasant to say the least, with no way of telling what you are seeing. I understand others had different results.

I'm not convinced that either filter type is any good for this purpose, unless the objective is to split-and-forget, in which case the OIII might be of limited use.
