Hi all
Tried something unusual this time, using the UHCS filter on the Rho Orphiuchus complex even though most of it is broadband reflection, but hoping it would cut light pollution and increase the faint red emission nebula at bottom. Large circle round Antares is internal reflection from the filters.
Its 10x5 mins ISO 400, masking used as well

Helix full field shot and one cropped to show full resolution.
9x6 mins ISO 400.
Modded 350D, UHCS and uv/ir filters. Berts magnificent flourite 300mm f2.8 lens.

I love the helix but the noise on the image is a bit annoying, to me anyway. Still its an experiment and it looks great in that sense has loads of possibilities. Yeah shame about the reflections, maybe a slightly different angle on the image so no bright stars are in field?
