Yet another attempt at NGC 3199..this time with an ED127/QHY8/EQ6/Baader 7nm H alpha filter

This is 9 x 20 minute subs
This is a challenging object-needs more exposure , or maybe a dedicated mono CCD rather than a one shot; actually looks much better on my processing PC compared to my internet PC-I really need to calibrate the two monitors (how? )
Its somewhat better than my last effort with the same camera but a smaller scope-an ED80

but still not quite there unfortunately
comments and suggestions appreciated
