I fully understand what you and others are saying. I also know a higher F number = slower. I had a celestron AM 114AZ (F10 I believe) before the dob. I have taken all advice onboard and went woth the Hyperions with my eyes wide open - I'll detail reasons below here.
From reviews they have decent eye relief (a major factor for me with Astigmatsm in my eyes)
Consistent relief (according to reviews) accross the range. The other EP's mentioned appeared to offer reviews of varying relief through the range...
Addon spacer rings that can change the focal lenths
Ability to use as 1.25 or 2inch
Carry case is a very nice bonus
Eaisly threads onto cameras if I decide to go Astro-photography down the line in a slower EQ mounted scope
Bang for buck seems to be in the right spot...
At my scope of F5.9 (say F6) I hope and feel that I am on the edge of getting away with most of the downsides of this range of EP - in faster scopes
The 5 and 8mm that come in the kit get great reviews on most scopes
As I am new ot the hobby, perhaps I won't notice about any minor imperfections that are there....this may change if I get more fussy going forward lol
And my scope is collimated every couple of days - so again....I'm hoping the EP's can hold their own.
I will definately be writing a review of each of them recieved. I will run them against a bringht star and drag it accross the full FOV on each piece. I'll then go for the old reliable moon itself and report back on sharpness and contrast etc.
All of the information, given by everyone has been greatly recieved, and believe me, I researched each and every suggested EP to the fullest. I've lieterally red pages on them. Hyperions were called out mainly for their soft edging at FOV, but also appeared to have the best ER of the bunch.....again all of this is based on my research on threads etc. At my F6 - I am aware this is possibly the brink of where they can drop off, certainly faster scopes of F5 and lower - they appear to need more correction at the edge.
