Currently there is no listing for a UV/IR Cut filter in the D32 AR protect window size that the ASI294 uses. So you would need to use an additional filter in your image path.
Sean or Katherine, are there any plans to offer a D32 sized UV/IR Cut filter/AR protect window? It would be nice to have, to help keep the pieces of glass in the image path to a minimum. I always seem to have reflection issues when I start getting too many bits of glass in the way. :) Also, the QHY183C comes with an IR/Cut window, so to stay competitive it'd be a good item to have. :)
