IC1795 in Ha (WIP)

Post by Paramount »

Hi
This is the first stage of a full colour NB image of this 'ghostly' looking nebula in Cassiopeia. I had a clear night and because the constellation is circumpolar I was able to get 12.5 hours of data in one night ( a first for me), the only interruptions during the night were one for a focus check and one for the meridian flip. This was taken with the FSQ106ED at f5 on a Paramount ME and a FLI ML8300. Exposures are 25x30 minutes with a 5nm Ha filter, auto guiding was by a lodestar and OAG using dithering.
Processing was as follows
Calibrated with Darks and flats + darks
Registered with Registar
Stacked in Maxim DL using sigma clip
Stretched using gamma stretch with value of 0.1 and saved to 16 bit tiff
Levels and curves in CS5
I'm just waiting for the weather to clear again so that I can shoot the other two channels.
A full size version is available at the following link

Thanks for looking
Best wishes
Gordon
