Very nice image! Define upside down. Your previous image was correct when Orion is in the west. The rotated (current) image is correct with Orion in the east. This for observers at mid southern latitudes. I like Iota Orionis at top right With M42 nebula ‘blooming’ to upper left which is your image rotated 90 deg. anti-clockwise. This equates to Orion in the north for southern observers.

There is back-to front (reversed) which your image is not. This is caused by an odd number of reflections in the image train. Seeing images of planets (or star fields) back to front is not ideal when trying to compare to a map of surface features. It’s not that difficult to reverse the image and most image software has this feature.

Anyway, I digress. Very nice image from a DSLR. Well done!
