i own a 14 and 20 explore scientific(100 deg) and the ethos range of eps as well.the explore is right up there with the ethos however both eps produce differnt but interestng views eg when looking at tuc47 with the ethos you notice the cluster is slightly brighter particulary the center stars,the same object through the same scope using the explore scientific shows the diffenent colours of the stars in the cluster particularly at the center(perhaps not as bright,but that might account for the colour identification) similar outcome with omega centauri the scopes i have used with these eyepieces were a 8inch astro system dob at f6 a10inch skywatcher dob,at f4.716 lightbridge at f4.5 ,16inch obsession at 4.7and 25 obsession at f5,the 20mm explore scientific ep is in my opinion the best of the lot and no paracor is neded 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 plossels, andrews specials or clones of older designs as some on this forum seem to do,or speculate on performance of eps they dont 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 enjoy

Sharp to the edge.
Whilst I run a 2" heater strap it's rarely needed - it just doesn't seem to dew up much.
I've heard how to wash it down, and will give it a go shortly as there is a little eyelash grease left on it after a public night recently. Should be fun.  |
