The Orion Nebula

I have no idea how much exposure ended up on this. A couple nights ago I was able to try a few hours of narrowband Ha and Oiii (2 minute subs), so started with HOO (which is a really nice pallette- first time trying that).

 

Then I added a previous year's LRGB to get more of the reflection nebula blue. Back to clouds now, so here is where it will stand.

 

With the cloudy winters it took me 3 years to get another crack at M42 , so I was happy to have the opportunity and play with the narrowband data.
