This was an initial image of the Horsehead Nebula (Barnard 33) and the Flame Nebula (NGC 2023) taken in 35 nm H-alpha filter that I was planning on trying a composite HaRGB, but the clouds have rolled in so don't know when I will get back to it, so thought I would see what the Ha looks like on its own.
The filter used is a Baader Planetarium #2458380 mounted on the front of the RASA 11, I did not remove the clear glass optic from the RASA and might go back and try again without it to see how much difference it makes.
I had a few issues getting this image as I had a number of technical problems with the equipment and lost 2 clear nights due to mount / guiding / software problems which I touch on briefly in the video.
PHD2 kept losing guide camera
Mount / CPWI locked up
Mount stopped tracking, CPWI showed tracking disabled
PHD2 couldn't adjust RA sufficiently.
