BORG Users’ Image

I got Orion wide-field images from BORG owners.  First one was taken by Guillaume Richard in Texas. It is 12 mosaic – over 8000 x 8000 pixels!! Great efforts, Guillaume.


BORG 55FL F3.6 + ASI 1600mm, Ha 12-mosaic

I shrank down the image size for the proper screen viewing. But you can download the original file at

He is using a following 55FL system. Quite simple.



An another one was taken by John Ottesen in Florida.

John, thanks for sharing your another new image. Very clean and transparent. Personally I love this film-like finish too!
One note:  take a look at Alnitak. Very clean star edge. No ugly reflections. This is the good test target to see the camera quality. I’m sure all of Hutech-modified camera users are enjoying the clean star edges.
