Subject: [SBIG] m8 HaRGB
Hi all,
This was more difficult than I was anticipating. I spent a good deal of time experimenting-with (mangling) Rob's HaRGB combination technique. Could have done with more SNR I think, and for some reason my Green filter was way out of focus with the R and B. Not something I was expecting. Could it be the Achromat? I have not noticed this before so I suspect something amiss in the filter wheel.
Anyway, here it is.
