Yes all images are captured using the 2600MC
The Duoband filter is a narrowband filter used for OSC cameras in light polluted skies. It works by only letting in the Ha and OIII wavelengths , so less light pollution , moon glare etc in your image capture
I should have attached some of Canon 600D images which are still great
I’ll attach 2 off them captured with the Canon 600D and the 8” f5 newt
M83 Southern Pinwheel Galaxy
M8 Lagoon Nebula
