Around 50 deg, not a true ortho in the strictest sense, but it was a design consideration. Others say they work well on DSO- my 18mm does. Faint galaxies will tell the tale I think. I look forward to Jupiter in it too.

The 10mm Delos delivered the best views I have seen of Juoiter :-)

I'm comparing this little EP to of my 2 best performers,10E and LZ. My 18BCO barlowed at least equals my 8D on the planets... I like orthos though, some don't :)
