Hi Jorge, nice pic.
could you please explain your post a bit better?
I am confused as too your distances.
you have two distances for this object.
I also would have thought the star would be much redder as it is a Red Super giant.
I note that you have no nebulosity in you image?
I can see the nebula in my 16" scope on a good night
This is not a criticism just an inquiry.
Cheers

Cool image. But, as Ron said. Isn't VY Canis Majoris a red hyper giant?

Huummmm! I agree. I used this star to adjust focus and I wrote that it was canismaj. But I really don't remember exactly who was it.

I liked the image of this star, because this I published. I tried astrometry.net and for my surprise ... she is Sirius !

Therefore, my apologize.
