My sample of the Bandmate II Nebustar (2018)filter was excellent,
with a 26nm bandwidth and high transmission % at 486.1, 495.9 and 500.7nm and <1% at 656nm (H-α)
Field testing showed it tied with a few other "UHC-Type" filters, all of which were excellent.
The sharpest star images were in the filters with close to zero red transmission, and the TV Nebustar was one of them.
Nebula enhancement was pretty much equal with the other top-of-the-line filters.
