I finally recieved the new SVBONY SV220 Sii+Oiii 7nm dual band filter, this is my first attempt at using it in combination with the original SV220 Ha+Oiii 7nm dual band filter to create a true SHO palette using a OSC camera. This contains a total of 6 hours of data, 3 hours from each filter. I split the colour channels from both filters in Pixinsight and recombined in to 1 image to get these amazinf colours.
