I am deep into a mosaic project. I have gotten 4 panels of it so far. The Ha
of this mosaic is what I am showing here. I have colour data for the first 4 panels although I think I will reshoot a few of them as they were a bit too heavily moon affected.
Proline 16803, Astrodon 5nm Ha filter using a Pentax 67 75m F4.5 lens autoguided on top of an AP1600 at my dark site. Good seeing but a part moon. I hand focus the lens.

I found it very interesting that there is such a large Ha area around Rho Ophiuchi which doesn't show up normally and also that large nebula above it. I am not 100% sure but I think its Gum 14 which I also have an AP Honders image of.
