Post by: Carole on Mar 24, 2012, 10:42:30
Managed to get 3 hours on this from Hereford on Wednesday night.
I did not use a LP filter which perhaps I should have as the subs were very orange. 

300 x 36 800 ISO,Modified Canon 450D
Guided with QHY5 and PHD
SW ED120 on NEQ6
DSS and PS CS3

Will re-process when I get home, so this is just a preliminary process:
