Horsehead - What filters to use?

[AndyThilo]

Trying to get my head around this. I've never shot it before, but tonight seems ideal. It will be with my 286C and either the L-Pro or IDAS NBZ (NBX replacement). Do most people shoot it as HaRGB? Is there any benefit to shooting multiple exposure times for HDR to try and control Altinak?

Just wondering how you got on with this with the current Moon conditions? I would have used the L-Pro to start with and  added some Ha later if it needed it.

I don't think HDR will help much with Alnitak. It normally becomes a feature, especially if it has diffraction spikes.
