Thanks mate. I posted some test shots in the Helix Ha thread in Deep Space. I have stacks to process from tonight so it's going to take me a little while to post the rest. Probably took over 400 subs in a matter of 3-4 hours.

They say it covers sensors up to 27mm. I'm shooting flats right now and I get very little vignetting. Just a hint of it with the QHY8 but much less than the 5" newt.

I think the Idas might have the edge on the CLS but we have not done some side by side comparisons. Some reviews think these are very close with the same band passes but we will see. When I get mine I will see what performs better but with the Aus dollar the way it is now who can resist buying some accessories.
When I was searching on the web for info/reviews about these filters I came across this guy who seems to get spectacular results using Hyperstar 3 with this filter and a C8, 5min subs  shows how fast these systems work and the Idas seems to control sky glow really well with a fast system. This is the filter I need now for what I do.

hopefully you can get results like this with yours.

Thanks for the tip Matt. I'll look into that filter definitely.
