Cool! For a first shot, you could have done way worse

How many frames did you collect and what was your exposure and gain?
What software did yo then use to process your image?
I would love to shoot Orion but a little help would be much appreciated!

I've never used a system as fast as 1.9. It must get an awful lot of light very quickly. Don't know what gain and exposure were used but looks like some parts got overexposed? Perhaps worth exploring stacking much shorter exposures but more of them for a similar total time? M42 is just so bright. I recall getting pretty good images just with my unguided Dob using 10s exposures at F 4.5. Just wondering what Sharpcap brain recommends? Tim
