Antlia SII 3nm Pro

Antlia SII 3nm Pro ultra-narrowband filter. Suitable for most emission nebulas, planetary nebulas and supernova remnants.

Antlia narrowband filters are designed to enhance the contrast. Contrast brings out faint features by reducing the background – the narrower the filter, the better.

All Antlia Narrowband filters have their edges blackened. This is critical to minimize stray light for a filter that blocks most light except for the narrow bandpass. Each filter is individually tested and scanned to ensure that the product meets the parameters we need.
