Hi Adam and Karl,
Yes, I bought a 5 x 1.25" filter wheel and a set of Antlia 3.5nm SHO filters. Prior to this I used a 2" Filter Draw with IR Cut and Duoband filter. I really enjoy the filter wheel and makes automation so much easier. I have it loaded with SHO, IR Cut, and a light pollution filter suitable for Bortle 4. The automation means that I can do SHO imaging on Carina and then switch to a broadband target without having to touch/change anything.
Interestingly with the Oiii filter I get less AMP Glow with the 183MC. I think it's because the GGB are being used in the RGGB Bayer matrix. Whereas Ha and Sii only fill the R. I am getting quite reasonable signal with the Sii which surprised me ( especially on NGC 3576).
For these targets I took subs with each of the filters, stacked individually and converted to black and white. I then bought each of the SHO layers together and applied the Hubble palate colours. As the Ha is dominant I used a 'live adjustment' layer to adjust the Ha to taste.
I used Affinity Photo on the Mac to both stack and process.
