Hi Greg,
Thanks for the feedback. I can post a 6 min IDAS exposure when home tomorrow. Of course, because the IDAS passes more light both the signal and the background are greater. To my eyes it made the CLS look even better, but what it does bring into clarity is how much slower imaging through the CLS will be. I'm starting to think I might be best served by both filters. The IDAS for mild LP and the CLS for massive LP.
