Hα active regions and animation (200 mm aperture)

[GreatAttractor]

Yesterday's results from the RC8/Aries ERF/Lunt 50 etalon setup (all shot with Chameleon 3 mono, ICX445). Seeing wasn't particularly good for this aperture, but I managed to capture a few stills and a short time lapse:

Shame about the seeing but I think the potential of this setup is huge, has the Lunt50 mod been documented anywhere?

I look forward to seeing more.

Yes, it's described here.

excellent images, 200mm of H/A aperture is an awasome thought!
