Pat great job by the way, the 60Da gets the pockets of HA in the galaxy really well.
For the LP have you thought about an Astronomic CLS-CCD filter? For a camera that is sensitive to HA this should give good colour balance (well recoverable anyway) and you can then push the subs a lot longer.
Here is an image I took of the rose nebula for 300 second subs with this filter and I live 10 Kms from the Brisbane CBD.
I will have to redo this with my Central DS Camera.

ooh anthony that is very nice!
i have the idas lps p2, but i would not know the differences between them to be honest mate
i tried the rosette a few weeks ago but i ended up disappointed because there did not seem to be much HA response at all in the 60da
i attempted a week or so ago to buy a narrowband ha filter here on iis but i missed out by a few minutes i think
do you think the filter you mentioned would be better than the one i already have?
pat
