California Nebula

[AbsolutelyN]

Last night's unexpected clear skies allowed me to grab more data on California Nebula. This is the previous 4 hour HA image combined with 5 hours of SII and one hour of RGB. So total 10 hours with Esprit 100 and 1600MM. Abandoned original bi-colour idea but might have another go later. Also got 1.5 hours of OIII but there was no nebulosity visible as far as I could see so didn't add it.
