NGC7822/Ced214 in HST palette

[Paramount]

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
Taken with
Takahashi FSQ106ED at f5
Paramount ME
Starlight Xpress SXVF H36
5nm Ha, OIII and SII filters
Guided by Lodestar camera and OAG using dithering
Fully calibrated, stacked, colour combined with a weighting of 7:1:5 for SII:Ha:OIII and gamma stretched in Maxim DL
16 bit tiff processed in CS2 with levels, contrast curves, gradient xterminator, selective colour adjustments. No sharpening or noise reduction used

The Ha version can be seen on the Nebulae 2 page of the image gallery of my website http://www.imagingtheheavens.co.uk

Thanks for looking
Best wishes

After all the interuptions this is a great result Gordon. A very traditional looking Narrowband image (probably the way they should look really)... Richard Crisp will love it!

Nice work!

A fantastic image Gordon.

Great detail and wonderful colours

Indeed Richard does like it. I had told Gordon that it is the nicest one I have seen this season done as a multispectral emission line image.

processed perfectly: no misguided sharpening, no silly Halpha luminance or the rest of the things that are done by those that have no clue what they are doing but simply mindlessly copy what they see others doing without even pausing to ask the question "what am I actually doing and what am I trying to accomplish?"

well done Gordon.
