I am going to purchase one of these 3 to go with my 12.5 Morpheus and 24 ES 68 degree eyepiece. The primary scope is a 10" F/4.7 dob, but I also use a C6 F/5 newt and will be building a new 17.5" shortly. That will leave me with focal ratios of f/4.5, f/4.7, and f/5.
I doubt there is a clear winner here, so how would you rank these? Which ever one I decide one will be the only one I add to my collection before the Golden State Star Party, and it will be the foundation I will build my eyepiece set on in the sub 10mm range. Note: I plan on adding a 17.5 Morph and a 30 ES 82 or APM 30 UFF later down the road. I do wear glasses and I do a lot of outreach. These eyepieces will be used often for both. Once I finish my 17.5" scope, I may add a few 100 degree eyepieces to complement this set.
If I chose the 6 Delos, I will most likely build a Delos set and go with 6, 8, 10 Delos. This leaves me lacking in the high power area for my max power would be 200x. I could aid this with my 1.8x barlow or a 4.5 Delos down the road.
If I chose 6.5 Morpheus I will Most likely build a 4.5, 6.5, 9 Morpheus Set (although I may get the 5XW over the 4.5 Morph due to EOFB issues the 4.5 mm is known for)
If I chose the 7 XW, I will most likely build an XW set and have: 5, 7,10 XW.
