Mike- I am looking forward to reading your report regarding your new filters  |
Yeah, I've used Astronomik filters for 12 years now... with a Meade 12" LX200GPS with Optec and Meade reducers, 80ED refractor raw, 200mm camera lens raw, Starfire APO with massive 4" field flattener and the AG12 with big 4 element Wynn corrector, with two different Starlightxpress cameras and two different FLI cameras and I have to say halos have never really been an issue
For example,
THIS was taken with the then new Astronomik halo free line 12nm Ha filter in my then new ProLine 16803, pretty good test I recon.
So in the end I think it really depends on your particular image train combo ie type of corrector, CCD window, chip cover slip, your coatings
and filters..?
Mike
