IDAS Clear (ODW) Filters

IDAS Optical Distance Worker Filters

The ODW Filter series by IDAS is a broadband line of clear filters which can be a fantastic pairing with their other multi-band or narrowband filter series. This filter line makes it astrophotography easy near city lights when paired with the NGS1 filters in particular. The night glow is heavily reduced thanks to the NGS1 and the ODW rounds out the rest of the colors well. On top of this, the ODW filters are all parfocal with the rest of the IDAS filters, making it a no-hassle process when swapping between whichever ones you'd like.

Full spectrum (clear) filter. Fully multi-coated. Par-focal with most of other IDAS filters.
