SH2-119 The CLamshell Nebula Narrowband

[old_eyes]

This data was taken on Pier 14 @Roboscopes in Spain. A reduced FSQ106 at 387mm FL coupled with an ASI 6200MM Pro.It was originally part of a three-panel mosaic from Clamshell to Pelican, but the Clamshell part never looked rright and unbalanced the composition, so I have processed it separately.

As a straightforward SHO palette image it was a bit dull (dominated by the Ha green). HOO was also dull as the O3 was rather featureless. However, a 50:50 blend of SHO and HOO images gave me a good starting point for this image.
