    Whichever is cheaper.

    Honestly, with a 70mm doublet, any decent Plossl should suffice and offer an excellent view.

    Unless you have issues with chromatic abberration on the brighter stuff...

    Another option is the Delite line. It's a narrower field of view though. But they're much lighter and less expensive.

    As far as the quality, I think the Delos is based on the Ethos optics. So it should be very similar other than the field of view. A wide field of view is good for a manual mount since you don't have to move it as much but your scope probably has a super wide field of view already. I'm not sure it would be a significant gain to go with an ultra wide view. You're just going to see more of the dark sky.

    I'm with Bryan here. With a 70mm achro, why bother. If one has the money for a Delos or particularly the Ethos, then I would first be looking at a better scope, such as an APO. In my view, that will give better views with a less expensive eyepiece than will the 70mm achro with a high end eyepiece.

    The Delos is based on the Ethos design but FOV was sacrificed to allow longer eye relief. Both would do good but it makes little sense to have an eyepiece of this caliber on a 70mm achromatic refractor. These EP's cost many times more than the optical tube. Consider televue Plossl EP's if you want to step up planetary performance as FOV is not required for that.

    With a 70mm objective (f/l unknown) I would agree and recommend some good quality plossls. You will have a 50 degree FOV but will help control the CA. If you are looking just for a wider FOV there are many eyepieces out there that are very good for much less than the Televues.
