I imaged the Horsehead yesterday. C8-ALT, .63 reducer, ZWO 294MC Pro. Using APT for capture. My lights were L-enhance 20 frames and 20 frames with L- extreme filter. When I used WBPP to integrate, it failed on the L- extreme shots ( no active frames). L-extreme lights were darker than l- enhance. 180 sec exp, 120 gain, both filters. The L- enhance lights integrated perfectly by themselves. L-extreme by themselves failed. Thanks! Pat

I would calibrate with WBPP then register outside of WBPP. WBPP works with the majority of inputs however it isn't perfect and perceived low signal can stump it.

The console should show you what went wrong. Getting that information would be an important part of giving feedback.

 

Also, this is a problematic way to combine information. Both of those filters will produce frames with significantly different signal, which will interfere with rejection algorithms and selectively cut signal. It may make more sense to stack the sessions separately and combine the registered integrations.

WBPP picks 1 sub for reference and anything doesn't get too close to it will be rejected. 

So it picked one of the higher SNR subs and of course it will dump all the narrowband images. 

 

Also, both filters needs separate flats for each. 

 

This would be 2 sessions for me and process them as separate sessions and mark calibrate per session also.

Thanks all! I understand what’s going on. Pat
