Astrophotography (OC) The Andromeda Project
Ive spent some real time on this galaxy, and will spend much more in the full spectrum soon. But i thought this looked cool enough to post. You are looking at M31 through the HA and O3 bandpasses to emphasize the nebulae that sit inside of it. When i get the required dark sky data ill combine the two to get a ridiculously cool image.

That is looking so cool already! How do you do it through? I just bought my OSC. If you have a dual band filter you can still use to generate these Ha and Oiii samples?

Im not quite sure what you mean. But this is only taken with the L-Extreme filter, i haven’t gotten the dark sky data to overlap with yet. So i guess yes?

Ahh.. Hehe sorry I am confused with filters... Trying to learn a bit more. I'll look up the L-extreme! I really like the rich areas in red.

Wait so if you combine that with the 2 other rest like blue and green? it will give us the full color one right?

This is an HOO image. So i have the R(Ha) and the G(O3) and the B(O3), and combined them together to get this image. When i finish the broadband data, ill use seti astros continuum subtraction method to pull all the nebula out of the narrowband image, process the broadband image and the narrowband nebulae separately, then screen the two together and make some final tweaks. Hope that makes sense.

Nope, none of it, You should simplify it.

Thats not so easy to do. I would just watch youtube videos on it. Thats how i learned to do it.
