Help with IR Pass Imaging

Hi Everyone,
Last night I had a go at using the Astronomik ProPlanet 742 IR Pass Filter.

I used the ASIAIR focus software and got the FHD down to 3.1. However I note that there are halos round the stars in the camera FITS images.

Is this normal or am I missing something? I also used a Duo band filter (pre and post using the IR Pass filter last night) and these images were fine (which would tend to exclude imaging train problems).

See attached image of Tarantula Nebula (Esprit 100, ASI183 MCP, Astronomik ProPlanet 742 IR Pass Filter).

Many thanks
