Here's the final version of the California nebula in hydrogen alpha. There are eight panels which is probably more than a skilled mosaic producer would have needed as I made some mistakes and was pretty generous with overlap. I think it would work really well as a narrow band image but this filter wheel unfortunately does not possess SII and OIII filters. I am going to try and get some RGB colour though.
Cheers
