Hi,
I grabbed another 6 20 min Ha images tonight for my little NGC6888 project, I now have 16 really good Ha images so I just need to get some G&B that will have to wait till the moon buggers off.
Anyway here's an uncalibrated (no flats wrong darks) taken with ED80, ED80 dedicated flattener, TS Off Axis guider,
Will post a caibrated Ha probably tomorrow.
