Here's the North America Nebula in HaRGB. Not actually sure if these colours are accurate at all, but I was going for a similar look to an image I saw comparing visible light with infrared from Spitzer. I think it looks pretty cool

My red filter has a defect on it, causing weird artifacts around bright stars. Anyways, not sure what's up with my inability to process RGB images. It seemed like I needed so much RGB data to get it to look decent. I don't think most people collect the same amount of data for both RGB and narrowband, but that's what I ended up doing. + My RGB data was binned 2x2, so idk what I need to do differently so that I don't need to collect so much RGB data.
