To help suggest a trick or two to help minimise CA what software for stacking and processing are you using?

Thanks, deepskystacker and Adobe photoshop. 

I know the optics aren't the best and fringing is to be expected but I wasn't expecting such a harsh defined halo. 

Hi All,

Looking for help on this as it doesnt seem like any examples of CA that ive seen before which can easily be removed in photoshop etc.
As in the attached images, the CA on the brightest stars has created dark halos at the edges which when the frames are stacked also stacks to create a horrendous output. The frames were taken on a Bresser 102/460 achro with an aps-c sensor.

Thanks
