NGC7822/Ced214 in HST palette

[GordonH]

Hi

I had previously taken some Ha data for this just over a week ago but the promised weather didn't materialise to finish it last week as I only managed to get 5 hours of OIII data in a four night period that was supposed to be clear every night (don't you just love the weather forecasters?). I can now image this area of the sky earlier courtesy of my neighbours cutting one of their trees down but the sky didn't clear until gone 11pm. I managed to get 4 hours of SII data over the last week with 5x30 minute frames last night (which again was supposed to be clear but was interupted by 3 hours of cloud)

Anyway, enough of the complaining, I've managed to finish it although som extra OIII and SII would make the image a bit smoother

Very good Gordon, the Ha layer on your website is very good.
