I have a 12" F5 dob and a Arcturus Binoviewer with an equivalent 2.6x Barlow to reach focus.
I mostly use the bino with the moon, planets and small DSOs like M13.
I only want a primary pair of eyepieces and I'm in doubt between the ones of the title.
My first views were with the Svbony UFF 18mm 65⁰ (around 7mm of real f.l) (which I bought for around 130€ the pair) and sold after I bought a pair of Explore Scientific 14mm 82⁰ (around 5.5mm of real f.l) (which I bought for 180€, the pair).
Now I have the opportunity to buy a pair of Morpheus 17.5 for 320€.
Some questions:
1. Is the Arcturus (AliExpress) Binoviewer prisms big enough to fill the full field of the Morpheus? I think the field stop is at the limit of that bino. Any one have tried it and can confirm that it doesn't vignette?
2. Is there a notable difference between the UFF 18 and the Morpheus 17.5? As I sold the UFF because I liked the bigger AFOV of the 14ES82, will I like the Morpheus more than the UFF18 and will make such a difference that I'll like it more than the 14ES82?
I have experience with large eye relief ep's like the 17ES92 and I liked it but I also like the "medium" eye relief of the 14ES100 or the 14ES82, so that's not a selling point for me.
