Narrowband accents

With the introduction of the NBAccent module in StarTools 1.8, a third parallel datastream type has been introduced; that of narrowband accents for visual spectrum augmentation. Adding narrowband accents to visual spectrum datasets has traditionally been a daunting, difficult and laborious process, involving multiple workflows. The NBAccent module is a powerful module that starts its work as soon as your load your data in the Compose module. Crucially it adds only a single, easy step to an otherwise standard workflow, while yielding superior results in terms of color fidelity/preservation.
By making narrowband accents an integral part of the complete workflow and signal path, results are replicable, predictable and fully tracked by StarTools' unique signal evolution Tracking engine, yielding perfect noise reduction every time.
Enabling narrowband accents in your wofklow, is as easy as loading the file containing the signal you wish to add as narrowband accents, and specifying the type of accents the file contains. Three possible types are selectable;
- H-alpha or S-II from a narrowband filter
- O-III or H-beta from a narrowband filter
- A combination of narrowband signals across multiple channels from a duo, tri or quadband filter (such as the Optolong L-Extreme or L-eNhance) or a combined single narrowband filter
Be sure to specify the correct type before continuing.
