Blue halos are a chromatic problem?

Next step, use the refractor as a guide scope instead of an imaging scope. That will fix the blue halos 
I like the image though .. Colours are ok except the core is burnt out. You have to layer mutiple exposures to get a good image of M42. Here's mine, and it still needs work  |
