Hi Owen, yes I have a few of each, Driven, GOTO & Undriven. I did choose the wider FOV for that reason. It's nice but I don't think I "need" it. The internal element count / i.e. glass aspect is a good point as it should relate to differences in contrast /sharpness. Thanks, JC

Thanks John, I did know that they Ethos/Delos/De-lite have that commonality, at the time I purchased the 3.7SX I figured it would be the best choice for that reason, and FOV of 110 it would be easier to catch a target if my gotos were off a bit - or on the porta-II or Dob. However, I'm not sold on the 110 degree FOV so much now, GOTOs have been good and I usually use 17mm, then 6-8mm and finally drill down to Hi-mag depending on the scope ...so I'm very close anyway. I'll find a 3.5 Delos, and update my experience ...but I'm pretty sure how that'll go JC

I'll keep looking for a good deal on a lightly used Delos 3.5 ...may have to try an XW(s) as well ...sometimes I think this hobby is worse than owning a boat! JC

Wow, as this was my 1st post - Big THANK YOU! to all those who replied! I suspect the Delos 3.5 will be the EP I prefer, certainly a subjective choice, but it sounds as if many of you have had similar experiences with Delos. I believe TV has a winner in that EP, I kick myself for waiting so long to try one and purchasing Naglers & Radians. I shunned them primarily because of "specs" the stated 70 AFOV - which frankly to me "seems" to have more FOV edge to edge than Naglers. Just goes to show you - you really just have to look through the glass - not the specs! I'm sure that has to do with a magical mix of eye relief and exit pupil. Thank you all again - I really appreciate the input!! John

Has anyone tried both TV Ethos 3.7 vs Delos 3.5 on an APO 80 or 100 refractor? I have an Ethos 3.7 and 6mm. Also Have 4.5, 8, 14, 17.3 Delos - and several Naglers & Radians. I didn't believe anything could beat the Ethos, ...until I tried a Delos, I was amazed - for me Delos beats Ethos ...I have Old eyes, 60 yrs now / astigmatism on low mag ( That only shows up on 14mm & up - I use the TV DIOPTRIX on & above 14mm, they are awesome for me ...but don't make any diff below 14mm for me). I know the Ethos vs Delos specs, Ethos should be superior but for some reason Delos works better for me IDK why. So - Has anyone tried Delos 3.5 (70) against an Ethos 3.7 SX (110)? I'm wondering other than apparent field of view, how they stack up. at 3.5mm or 3.7mm the depth of field is minimal - I get it. However I seem to get a tad more depth out of a 3.5 Nager than I get out of a 3.7 Ethos ...wondering about the 3.5 Delos. I thought I would buy one used (Kinda hard to find), if no difference other that FOV I'll keep the 3.7SX, but I thought someone may have some insight out there ...maybe the 3.7SX is as good as it gets for sharpness & huge FOV. I'm just not that enamoured with my Ethos 3.7, wondering if the Delos may be a better fit for me & my aging eyes. Any related experience anyone could share?? JC
