I have imaged for years with a Canon 30D on a 8 inch F4 Newt. I switched to OSC ZWO 294 MC. It is mounted on my C6 with a F6.3 Celestron reducer and the correct 105 mm distance from reducer to ZWO 29 4 sensor. I imaged the Rosette nebula other night 20 frames,gain 280, 60 sec exposures, 1x1 bin. My old setup was super on IR DSOs. Too slow of scope, C6 F6.3? M42 was super, lots of color detail. Do I need a filter to pick up the IR? Vignetting is bad.
