What a great explanation of such a fascinating phenomenon. One thing I love about astrophotography is that it drives people to learn more about the universe and physics, even if they normally wouldn't be inclined to. 🙌 Well done!

I got turned off with these Ha filters. Got the Astronomik filter for Nikon full frame. It does not slip in as their video shows. Have sent them numerous emails and they can't even be bothered to respond. Pathetic.

Is there anyway to shoot in monochrome format from a normal DSLR camera ??? And will it give better results???

No. DSLRs have a bayer color filter array backed into the sensor

@@pruthuvanara1243 if you’re shooting with narrowband I could see that working but without that bayer pattern removed each channel will still get different values with green still being double. Might be more headache than it’s worth when processing

You can use Ha filters with a DSLR but you should just extract the R channel from RGB and discard G and B completely
