This filter will usually be found mounted inside the ST-9E's filter wheel.

This Custom Scientific filter is designed for near-infrared photometry, although its response curve is considerably broader than the standard I band. The I-band filter is not parfocal with the SBIG filters, and observers will need to refocus the image whenever they change to or from this filter.
