Hi
I am off work on annual leave for a couple of weeks or so and it makes a change to have some clear skies to coincide with that even though the hours of darkness are a bit short. This is a narrow band image of NGC7380 in Cepheus which doesn't seem to be a very popular target for some reason. This is the first time I have imaged this in full colour, I had previously done it in Ha with the BRC-250 a couple of years ago. This can be seen on my website http://www.imagingtheheavens.co.uk
It was taken over three nights and is 8x30 minutes each for Ha, OIII and SII which were then mapped to the wavelength ordered palette used by Hubble. It was taken with a FSQ106ED at f5 and Starlight Xpress SXVF H9 on a Paramount ME, auto guiding was by a Lodestar and OAG using dithering.
Processing was levels, curves and colour balancing

Thanks for looking
Best wishes

Excellent result Gordon, very nice, love the colours :thumbsup:. I agree, not too many images of this neb around but its structure really lends itself well to wavelength ordered imaging. Did you have some issues with focus or seeing?..just looks slightly soft for a narrwowband image?

Hi Mike
Thanks for the comments, seeing was very poor when shooting the OIII and the stars did appear a bit bloated for that channel, I had to refocus after about an hour for all channels with the temperature drop in the summer at about 00:30. This may account for the softness in the image
Best wishes
