For observing DSO’s using Newtonian reflectors f5 to f6 from 6” to 12” you can’t go past the 24mm and 27mm TV Panoptic , good eye relief 15mm and 19mm respectively , 68deg apparent field of view and beautiful contrast / sharpness
If your looking at a long term investment for observing DSO’s with 8” newts and above my 21mm Ethos does it for me , supreme views at a rediculous cost but I had to have one and did not regret spending the money
