Antlia HA & OIII 3nm Pro Narrowband filters [Slow aperture versions]
Slow aperture versions, Not for RASA. I have two of the 3nm filters available, both 2" and both pristine, OIII and HA, they are also the threaded type. Fabulous filters for narrowband work, 3nm makes all the difference. $500 each or $450 each if you take both. These retail for $700+ each.
Postage is free to anywhere in Australia.
Cheers,
Bill.
