I thought you said "let's have a quick conversation about life." This was going to get heavy!

[@GediAstro]

Ha ha! That would be some heavy stuff :) Luckily we're just doing some quantum physics, relativistic theories and questions about the universe here - The easy stuff :)

[@SunriseHorizon]

Greatly explained, thank you 👍

[@GediAstro]

Thank you! I appreciate that!

[@demax25]

Thank you for the good explanation, finally I am getting a little insight how filters and Monochrome cameras work.
btw, my son is also studying Physics and astronomy, but his explanation is not so clear ;)

[@GediAstro]

Thank you so much for watching, I’m glad it helped! Also, congrats on having a really smart kid, in my opinion astronomy is the hardest field within physics, I personally didn’t make it all the way but had to switch to atomic physics in the end to get my degree. 🙈

[@gerardford1116]

Very informative Gedi, thanks for sharing this!

[@GediAstro]

You are welcome, I'm glad you liked it and thanks for watching!

So a question: is the Optolong L-Pro a broadband or a narrowband filter? Is the relatively new Optolong L-Quad Enhance a broadband or a narrowband filter? If a filter allows 4 or more wavelengths of light to pass but each wavelength is confined to a narrow band, which category does it fall into? Thanks for the explanation on filters - very helpful.

[@GediAstro]

I’d say that both the L-Pro and the L-Quad are light pollution filters, their bandpass is ranging from about 100nm to 30nm (hard to tell, but it’s somewhere there). The main difference between them is that the L-Quad has blocked the light around 600nm and have a very small reduction of the bandpass on the others wavelengths.
As I mention in the video, a narrowband filter is defined solely by it’s bandpass, starting at around 25-30nm and less. So the only thing that defines a narrowband filter is it’s bandpass, not the amount of wavelengths it targets. For example, the L-enhance is a narrowband filter targeting H-beta, Oiii and H-alpha but at pretty big bandpasses (25nm and 12nm) whilst the L-Ultimate narrowband filter let’s in “only” Oiii and H-alpha at 3nm each and easily outperforms the L-enhance. I hope this helps and thanks for watching!
