My filter set turns up next week (only took 6 months).

So am doing homework on how to combine Ha data (taken with a mono camera) onto a RGB image (taken with an OSC).

Pixelmath (Pixinsight) would do it.

I need to study Pixelmath, but can't seem to find a 'definitive' resource.

Just bits & pieces. It seems like everyone is in the same boat.

Any leads?
