If filter with an Orion starshoot autoguider??

Does the starshoot autoguider need an IR filter to work as a guider? I realise for photography with an achromatic telescope bloating of stars by out of focus IR is a problem ,but does it matter for guiding? An IR filter will reduce sensitivity. Would be grateful for some advice

Slightly blurry is actually better for guiding as the centroid is easier to find than in burnt out star profile so I wouldn't worry about it.
