13mm or 17mm Ethos for C9.25?
Hi, long time reader, first time poster to the forum. Always an educational read and hoped I might get some help from yourselves on the below question!
Need some advise regarding best Ethos Eyepiece choice for a C9.25 (non Edge HD). As a bit of background, I have a Evolution 9.25, with a Denkmeier PowerSwitch Diagonal (S2 model) which allows for slide in barlow and focal reducer, and have 35mm extension tube giving options for 2x barlow, 1.5x barlow, normal, x.83 reduce and x.66 reduce for every eyepiece. Great bit of kit and cant imagine observing without it with my SCT. To get most out of it, looking to ratify my eyepiece collection and looking to get a premier eyepiece as the workhorse for observing (when not binoviewing).
Kind of narrowed it down to Ethos 13mm or 17mm (having looked through 100 degree ep it works for me), and leaning towards the 13mm. Reasoning is that currently the best experience I tend to have is with my 11mm ES82 (pin point sharp to edge of FOV), and nice level of mag particularly with the x.66 reduce in place (not bad without too). Just a happy place kind of combo, so keen to replicate in 100 degree if possible.
Also have a 30mm ES 82 (amazing eyepiece), but find a dont use / like the view of 2x or 1.5x barlow as much (15m / 20mm equivilent) as edge isnt quiet as nice in these modes (still pretty good though). Not sure if it is indicative of c9.25 with higher mm eyepieces, so considering investment needed for an ethos was keen for any feedback of anyone you has tried a C9.25 (or any Cx SCT) with either 13mm or 17mm Ethos, and how the edge of field held up with or without a Focal Reducer in either? Any help is greatly appreciated and thanks again!
