Wow! Awesome details - especially around the keyhole. Did really well with Ha using a DSLR - normally better suited to the dedicated monochrome astro cams (no Bayer matrix). Just recently bought a few Astronomik clip in filters for a full spectrum 6D (CLS-CCD, 12nm Ha and L) with their new XL Clip filters for full frame cams. I'm finding a bit if darkening on the top and btm of frame, but nothing that can't be fixed in post. How do they go on a 60Da?
