Nice Martin, you have us all at a distinct disadvantage now. Two sites to choose from. I'll bet there are not many nights one or both systems are not operating.
Paul - it is certainly great fun having two observatories seperated by an entire hemisphere. I am particularly thrilled when I am imaging on both simultaneously, and I have had to put labels on the monitors to remind me which system is which.
You are going to see many artefacts if you are only looking at the 200kb thumbnail. I am always very careful about any sort of artefact from processing, so I dont think you will find those in the full image. As for the reflections - they do not appear to be a problem on axis, but off-axis is a different story. There again, I have 3 high quality scopes from different manufacturers and I have owned 3 different types of filter - and it doesnt matter - you are going to get reflections and you have to live with them either being outrageously bad or tolerable.
Please keep the smorgasboard of fantastic images coming Martin. Loving every single one of them, this image included of course. Gosh you make NB look easy.
You are really imaging Deep-Sky at a level the rest of us hoi-polloi can't reach at present....but I have to say raising the bar as you have, is a good thing
