My most used scope is a 85mm tv85. FL 600mm. F7. My medium power ep is a 13 Ethos. My high  for planets is covered from 6mm down to 3mm. I enjoy all targets. Open clusters, glob clusters, nebula, ect. I can't decide between the 8 and 10 Ethos to complete the gap. I would imagine the 10 at 60x might be nice for a tight view of some open clusters. I imagine the 8 might win out with globs and certain nebulae. I would like some opinions. Maybe food for thought  to help decide. Anyone have a 8 or 10mm  ethos to compliment  a 13?

I've got the 10 Ethos to complement a 12 ES 92.. It's more of a different viewing experience than it is a 'complement'. But that being said, you would probably notice more of a difference from a 6mm to 8mm than you would a 13mm to 10mm. Medium powers are less distinguishable to my eyes than higher powers.

The 10 Ethos is really good though. I rarely use my 8mm Delos.. Just one of those focal lengths that gets skipped.

Also have the 13 Ethos as my mid-power eyepiece. After getting a good deal on a used 4.7 Ethos I replaced my 8 Delos with an 8 Ethos, and now only use the 3-6 zoom with my tracking mount. 

 

You can't go wrong with either of your choices.

I would think in you case the 8E would be a better choice.

 

For casual viewing in my 120/840 F7 I use the 8E, and for closer views I slip in the 4.5D

For casual viewing in my  80/400  F5 I use the 6E, and for closer views I slip in the 3.5D

 

For casual viewing in my C-8/E (w/.7fr) I use the 17E, and for closer views I slip in the 13E

For casual viewing in my C-6 (w/.63fr)  I use the 16N, and for closer views I slip in the 9N

Hello,

I looked at the power difference between the Ethos eyepieces and decided on the 13 mm, 8 mm, 6 mm, 4.7 mm.   I would miss more the higher power and better power spacing of the 8 mm ethos. 

 

I would still like to have the 10 mm but cost enters into the decision.    Ideally it would be nice to have both.  That is the grand TV's plan.
