Nebulas - North America and Pelican

NGC7000 and IC5070: the North America and Pelican Nebulas. Taken with a monochrome camera and 200mm lens from a distance of ~1800 light years. Interesting fact - the North America Nebula covers an area four times the size of our full moon.

nice image, and thanks for the link

Which filters brand you use?

I am using the ZWO filters. I would like to get the Chroma or Astrodon, but for now the ZWO will do.

Ah ok, sure they are top quality ones.

I heard there is a new brand that has some narrower filters, could be better than ZWO at least, less quality than AD/Chroma, results sounds promising, and i think i will get only one filter which is Ha to pair with my Chroma filters, my Astrodon filter Ha 5nm is nice already, but i want to try that narrower one with my another second mono camera.

I’ve looked at some of the narrower ones. I would like to see a side by side comparison of a 5nm and a 3nm Ha. I am curious how much of a difference there is, and I’ve wondered if it would be a little better in light polluted skies.

3nm will get you little more contrast of the target because you are narrowing more on the target rather than background, and 5nm is not bad, i went with Ha 5nm because i wanted to have NII signal included, and that is why 3nm is narrower because it will remove NII signal as well, i think if i bought that cheap Ha filter of 3.5nm then i will be closer to Astrodon/Chroma 3nm one, i don't need to make it too much narrow and i don't need to buy 3nm very much, my 5nm is working great under my sky LP, and with 3.5nm i will be even more happier i hope.
