The Stars of Orion - 300 image mosaic in the making.

Ten more panels making it 20 total with 17 left to edit. I had a big season transitioning to dual scopes and I’m posting this one ahead of finishing out to Betleguese. I’m on a mission to make it to Betleguese before Orion sets for the year but Weather will play a big part. I’ve got roughly five hours a night left until March. It’s going to be tight. Regardless, I am on track to finish at least 25 panels this season,

Maybe even 13 more if I get the time. It’s worth noting I got 3 before switching to the dual scopes and 22 after with the week in Marathon Texas. If it has been clear all week

for us, I’d of finished this leg.

Integration per panel:

12x3min L

12x3min R

12x3min G

12x3min B
