The VHT is "mid-band" Nebula/LPR filter that is the perfect match for smaller scopes, or binoculars that can use filters. This filter provides a good balance between the NPB and GCE with regards to contrast vs. field background and star brightness. In addition to the VHT`s excellent visual performance it is also a very good astro-imaging filter with high H-Alpha transmission, and transmission exceeding 90% from 486.1 to 501nm, which includes H-Beta and both Oxygen lines. As with all DGM filters, the durable Ion Assisted Plasma Coating Technology used to produce your filter ensures decades of high quality performance.
