Description

I wanted to do a mosaic of Orion in RGB, and a couple nights into it, I realized it is going to take a while, like a few seasons. With moon in play, I switched to Ha and it was more manageable between the panels. Stacked them all in APP as I was impatient to see if PixInsight will work or not. 

This is 12 panels, each 1.5hours at 15 min subs. I shot little over an hour of M42 with 60 seconds, yet the core is still blown out with HDRMT. 

In the midst of collecting data, my EQ6 stopped tracking one night. Found out a screw was fractured into the mount head and a trip to the local hardware store got it back working, to an extent. 

Hope you like this result. Clear skies!
