At long last I was able to try out my new H-alpha filter on my Canon 60D. This is the newer 6nm filter from Astronomik - my previous filter was the 12nm. I was able to do a direct comparison on the very faint supernova remnant Simeis147. On this target there is a distinct improvement with the narrower-band filter. The new filter is even more expensive and for bright nebulae the extra cost is possibly not worth it. But if faint targets are what you are interested in then it is a big step forward.
The images have had gradient removal and log stretches but no other processing.
