Hello everyone.
First image of my new nomadic setup with a Sigma ART 135mm + 2600 AIR camera combo.
I also took the opportunity to test the Optolong Astronomy Filter L-Para in high speed at F1.8 and it works very well.
I'd never done much Orion before and I have to admit that the processing to integrate the Ha with the RGB is pretty tough...but I managed to make a version that I liked while retaining the dust and colours of Orion well.

 

 

 

 

Setup : 
Sigma ART 135 open to F1.8, I didn't even need to redo the stars, it was clean and Blur X did the rest.
Asi 2600 mc AIR
zwo AM5 mount
35x300s without filter  
54x300s with Optolong Astronomy Filter L-Para 
31 January, 1 and 2 February
Houdemont (54) for the L Para 
A field near Lisle En Rigault (55) for the part without filter.
