What is Hydrogen Alpha light anyway ?? And why it's so useful for astronomers

[@scottp6319]

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!

This guy is the best, he always answers questions, huge positive.

Thanks!

Thanks!!!

[@kalef1234]

perfect topic while i wait for my 12nm astronomik clip in filter! excited.

[@johnspringer-vy1is]

This was exactly the information I was looking for. I'm not a photographer. Just got interested by some recent hubble photos that talked about the H-alpha emission and now I know. Outstanding presentation.

[@darenputman6447]

Nicely put! Thanks for this!

[@MakeAMark]

Nice straightforward piece.

[@taktsing4969]

Does red shift change this 656nm value?

[@pruthuvanara1243]

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

[@kamilkp]

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

[@pruthuvanara1243]

@@kamilkp someone recommended me to convert rgb images to monochrome in post processing and use it, possible ???

[@bakerfx4968]

@@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

[@kamilkp]

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

[@harveyfreed6342]

So a full spectrum modification should collect H alpha .

[@kamilkp]

Yes

My 2 inch hydrogen alpha filter and my PVS 14 night vision device make the night sky into a whole new world

[@DLMVegas]

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.
