This is the very first
test shot with our new Rasa 11 up in Happy Jack. The setup needs
alot of adjustments and refinements before I can call it routine,
but it at least proves the filter holders work, and the Baader
filters do their job. One hour of RGB data followed by one hour
with the 3.5nm f/2 Halpha filter. Collimation is good, but the
camera mount needs some tilt adjustment. The 35mm sized chip
has a good 2x3 degree field here, and this will work for many
targets.
This image is centered
on the dark Barnard 92 Horse Head nebula, and features a rather
extensive record of IC434 and NGC2024. The mottling on the left
side is intriguing to say the least. The only other area I have
seen such structures is in the "Fox Fur" nebula in
Monoceros.
