The scopes I have used with these eyepieces were a 8 inch Astro System dob at f6, a10 inch Skywatcher dob, at f4.716, Lightbridge at f4.5,16 inch Obsession at 4.7 and 25 Obsession at f5. The 20mm Explore Scientific ep is in my opinion the best of the lot and no paracor is needed for it in any of the aforesaid scopes (nor for the 14 explore scientific). The same cannot be said for the ethos in faster scopes. The price is not relevant: its about performance. I am not talking about comparing the performance of these eps with cheap plossls, Andrews specials or clones of older designs as some on this forum seem to do, or speculate on performance of eps they don't have or have any experience with....the Explore Scientific range is excellent and does not need to be compared with the Ethos its like trying to compare a falcon with a holden ....pretty much the same.

Based on what you say, the price differential, and the high exchange rate, my ES 20 is the way from Opt Corp
I will compare the views from the ES 20 with those from an Andrews 30 to see whether the higher cost of the ES 20 is worth it.
