Hi Ben and
mate , as said the Hyperion gets good reviews every where , great eyepieces . I dont have any but a few mates up here hav a few of them and from what I have seen , no worries there .
.
on the 2.5 , well you will be pushing 300x ? and Ben as said that sort of power is only used on those exceptional nights , a few a year , but hey if its a Hyperion she is a keeper , Just enjoy the night sky as you have a great scope and good eyepieces
.
ps. I have a 2.5 Vixen Lanthium and it does not get used often , but when the atmosphere allows ..
well worth the wait .
Brian.
