Looking good Richard!

at f/12.6 signal builds slowly. even more so using emission line filters.

but still perseverence is occasionally rewarded.

I have quite a ways to go: I have a total of 25 x 20 minutes: a hair more
than 8 hours

but we are beginning to get some idea of what it might look like in the
wavelength ordered palette

it was taken at F=5760mm using the 18" classical cassegrain at f/12.6

the camera is the FLI Proline 9000 with Baader Halpha and FLI S2 and O3
filters

all subs were 20 minutes
