Dear group,
I jumped on the opportunity last night and the clear skies to pursue the Horsehead Nebula in Orion and in spite of the dominant presence of the 16-day old moon with a phase of 94% and only 30 degrees further north.
I was quite pleased with the quality of the result in lieu of the very bright sky thanks to the nearly full moon. I made the mistake of shooting B33 in portrait rather than landscape mode and this is something I will rectify when I sit down to officially shoot an (Ha)RGB version and under moonless skies.
For a result based on four hours total exposure time using 20-minute integrations an a Baader h-alpha 7nm filter, please see http://www.perseus.gr/Astro-DSO-Nebulae-Dark-B33.htm . It will be interesting to see the improvement in contrast when I revisit B33 and without the moon being present.
Anthony.
