Hi all , I have a 2nd hand GSO superview 30mm on the way that will live in the eyepiece case locked on the back of my 4x4 along with my SKY90/VixenSP set up so I always have a scope with me where ever I go .
Anyway , I have jacked up a night soon , the next dark sky night in a couple of weeks time where we will be testing this GSO SV against my beautiful TV 27mm Panoptic in a variety of scopes , a 66mm AT quad , WO 110 triplet APO , my 127mm Istar f8 achro , my 9.25 SCT , 10 inch GSO dob and hopefully a C14 as well by 4 of us experienced visual observers . This gives a good spread of apertures and F/L's , as well as scope types.
I will be taking notes all night and hopefully I can read them the next day .
The testing will be done hopefully blind so there will be minimal pre-conseptions as to what eyepiece is being looked thru at any given time .
I know my 27mm Pan is awesome , but these Superviews get rave reviews every where so it will be interesting to see how a $40 GSO compares with a $350 Panoptic ,, stay tumed and if the weather is kind it will happen soon .

A nice spread of scopes Brian. Great to add an ES 28 68º if you could. From all I read the 28 is very close to the 27 specially in longer FL scopes. I love my 28mm. Look forward to your report! Have recently got my easy G+G scope done...an EQ3 with duel axis drives and an ED 100 f9...nice. A bit easier than the 150+kg set up of the 6" f12!!!
Well its been a while and the short answer is , the TV is way better in my sky90 a friends 110mmf7 WO triplet , SW 10 inch f4,5 dob and iStar , still the SV put up a good showing and at 1/10th the cost we all thought it did very well .
In my C9 1/4 and a friends C14 the difference was harder to see as expected with a f10 and f11 , I was quite amaized how well the 30mm SV performs in the longer scopes and without a 27mm Panoptic to compare it to , I would personally be very happy with its performance here , almost as good to the edge , great light thru put and the same realitivly big field .
The few of us that tested them all agreed these GSO SV's are amaizing value for money and will perform brilliantly in an iStar f10 or longer refractor ,so don't be shy guys , really good eyepieces that don't break the bank .
I have always found it difficult to find something better than my 27Pan. I find it very well corrected at the edges as the focal ratio decreases. You pay for it through pin-cushion, but this does not bother me.
I'd love to have a bunch of TV eyepieces....but I don't think I ever will. Personally at f12 and in my f4.8 Newt, with an ES HR coma corrector, I'm really happy with the ES 68º series...all of them and ES 18 11 8.9 6.7 and 4.7 82º set I have. Then there is the UO VT Ortho's 25 18 12.5 9 7 6 5. Nice post Brian. My first intro to 68+º eyepieces was a Superview 15mm.... thought it was brilliant then, which it was until I knew better. Matt

I have had the GSO 42mm and 50mm super views for a while and recently picked up the 30mm. The 42 and 50 worked well in my F/10 11" SCT. I just tried the 30mm super view in my 150mm F/15 refractor that I recently finished. It truly was a super view. Great value eyepieces when used in long focal length scopes. Russ
