Description

I tried a test this morning framing the Horsehead Nebula and the Flame Nebula, leaving plenty of vertical space for all the beautiful hydrogen. But as we all know. Alnitak can often overwhelm all the details on the edge of the Flame Nebula. 

So I limited exposures to 60 seconds, and took 180 with my L-extreme. Overall, this the best I've done controlling Altinak so far, although the star itself is still fairly washed out. We also see the persistent L-extreme halos. 

I'll try this again soon with 180 x 60 seconds, no filter next and see what we get. I'll also compare 360 x 30 seconds when I can. 

Thanks for looking and clear skies!
