Hi Folks,

Sometime ago my SBIG decided it needed to go visit the family at the factory, so while it was being repaired, a good buddy from the ASV loaned me his Modded & cooled Canon 40da to play with, thank you Phil :)

I was astonished and intrigued as it came with a 6nm Ha filter in place, which immediately made me go hmmmmmm:question:. So I have been waiting for a clear sky for a chance to experiment.

This is the result of blending 90 mins of Ha with 3 hrs of RGB. Shot with the IDAS filter from my suburban backyard. I have more or less followed the Starizona method of Blending as seen here -http://starizona.com/acb/ccd/software/ps_hargb.aspx????

This example is perhaps a bit vivid, but the potential for the technique is amazing, and should keep me happily shooting for another season until I eventually persuade her indoors to allow me to get a mono camera and filters.;)

The SBIG is back this week, so it's time to get myself an Ha filter, and out to dark skies again!

Anyway, thanks for looking and all feedback and constructive comments are most welcome. The HaRGB combo and original RGB image are below.

Update: Ha Sub added as well.

the HaRGB definitely packs more punch!
A lot of people seem to use 12nm Ha filters in their DSLRs but it looks from this pic going finer is possible. any chance of posting a Ha sub?

Cheers

Rusty
