ASTRO: Holmes in Halpha
Richard Crisp wrote: it's the filter I had handy :-) http://www.narrowbandimaging.com/com...olmes_page.htm I got thinking later (after the clouds rolled in) that I should have done that for the lum image. But at the time I didn't know it was mostly dust we were seeing not gas. That's usually so far out of the Ha passband to be invisible. I leave for a few days starting tomorrow so can't follow it but then the clouds are to be back so it doesn't much matter. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
