Quote:Quote:two naglers. My eyes cannot take in more than about an 80* fov anyway. But there's far more advantage to the Ethos than mere field width. The higher contrast, extra detail and general quality of view are what the advantages of the Ethos are for me. I've directly compared the view through my Ethos and Naglers, matching focal lengths as closely as possible, and definitely see a difference in the favor of the Ethos compared to the Naglers. These comparisons were done using my TEC 140. In my SCTs, not the same level of advantage, but still there.

Quote:A used Ethos & good Barlow could net ya, effectively, TWO Ethoi! I have such an arrangement... a 13E, and actually TWO excellent Barlows- an AP 1.6x Barcon, plus an older UniversityOptics 2" 2x long-fellow... so essentially have three excellent 100* FLs to work with! 13mm..... ~9mm..... ~6mmAll acquired "used" for probably near your budget number.

Quote:GeneT: EdgeHD 800 is what I am aiming for. DSO is most important, eye relief is great and encouraged, I haven't found anyone with actual TV pieces except for plossls... I think they're afraid to take 'em out.
Quote:The 8 inch has a focal ratio of F/10. At F/10, there are a lot of eyepieces with usefully wide fields of view that do not require Ethos or Nagler level of off-axis correction to provide quite wonderful views.

If your scope were an F/5 refractor or Newtonian, then Naglers and Ethos's make a lot of sense but they do represent a major investment..
What other eyepieces do you have, what has been your experience with less expensive wide field eyepieces?
Quote:Quite right. But the C8 benefits not only with sharper edges on the premium EP's, on-axis presentation is also better on the eyes, the clarity is nuanced immediately. The slow F/10 8" SCT scope is not a reason not to get top EP's, it will benefit much from premium EP's, going by experience with it, and not just at the edges. Just 2 cents of course, thanks.Best,
