I'm still trying to process this year's Astrofest data and I've been leaving the difficult ones till last. I've had at least three attempts at this one and finally went back to PS today to allow some easier masking to get the job done.
This is 44 x 5min Ha and OIII taken with my SN10 on the EQ6 with a QSI683 and my first serious attempt at a bicolour NB image.
Here's the full res version:

As always advice gratefully received.
Thanks for looking.
