SuperView EP's?

[ballaratdragons]

I am thinking of getting a 2" EP.

For use with a GS12" f5 Dobber which one would you recommend out of these:


Andrews GS 2" EP's
________________________
26mm (fully multi-coated, antislip grip and rubber eyecup)$79
32mm (fully multi-coated, antislip grip and rubber eyecup)$89
40mm (fully multi-coated, antislip grip and rubber eyecup)$99



SuperView GS 68 degree 2" EP's (5 element)
________________________
30mm $99
42mm $99
50mm $99



Or your own recommendation of a 2" up to $100

Thanks

Well I like my 2"30mm superview more then my Meade 26mm 1 1/4......I may change my opinion once I get my Nagler 17mm 2"......

Tracking now.........my eyepiece is in Australia.......wahooooo...cant wait.

Hi Ken,
What E/Ps. do you have now? If you have E/Ps ranging from 6mm say to 25mm in 1.25inch, then a Barlow will double your mags.
A personal comment if I may, I use a few Meade E/Ps with my 10" f4.5 DOB. They are series 4000 Super plossls. I have the 6.4/9.7/12.4/15/32mm and #140 Barlow + S4000 Ultra Wide Angle 14mm.(1.25+2"), along with an 18+25MA. They give crisp images but are a bit pricey at about $140 ea.(NOT the UWA,near$700)!
A few of our members have the Andrew's range of E/Ps. and are very happy with them. There's not a lot of diff. in image quality.
If you want low mag with a reasonable fov, then go with the 30mm Superview 68 degree E/P.(50x@.44degree). I'm not sure about the 42mm SV68. You might get some vignetting, due to it being an f5 t'scope.
Your best bet is to TRY/BORROW a 42mm E/P and see if it's O.K. before you buy.
Why not go for a 12 or 15mm SV 68 if avail.?Cost???
HTH. :2thumbs:

Currently have 6mm, 12.5mm and 20mm.

Don't know anyone with a 2" 42mm SV.
2" 12 & 15mm SV 68 not available.

Sorry I didn't mention it before but it is for Virgo and Fornax Cluster hunting and Sombrero, Sthn Pinwheel, Tarantula etc.

No astrophoto work.

Ken my advice is dont get the "Andrews" 2 inchers.
I got the 26mm and was very dissapointed by its performance at f5. It was then that I learned what they meant by "seagulls".
They are a 3 element Kellner basically. It may work fine in an f10 sct , but totally unsuitable at f5.

For $100 the 30mm superview is your best bet and will equal or better anything this side of a 27mm panoptic. The 30mm will give a 6mm exit pupil at f5 which is about as big as you want to go.

I hope to do some galaxy hunting myself before the moon returns. This one over here on the left i want to take another look at :)

Thanks Geoff and Rajah.

Looks like the 30mm SuperView wins so far. I thought it would be a good mid-range EP.

I know the 50mm would be useless, but included it in case someone had a good review of it.

I will be ordering on Mon or Tues so I'll keep an eye on this thread until then.

Thanks heaps. :thumbsup:

What does the term "seagulls" Mean?

[ballaratdragons]

The shape stars take in the extremeties of FOV in some EP's

[Starkler]

Or in the case of the "Andrews" 2 incher, starting from about 40% of the way from the centre to the edge ! After such an experience I resigned myself to looking for a televue panoptic and considered my $140 wasted, which was what the 26mm cost at the time :doh:

Your limited buy the f5 ratio to a 35mm EP so go with the GSO 68 deg 30mm SV 2".

I have the 40 mm (see review section) and it works great in my f6 and O.K. in a mates f5 , but exit pupil comes into play at f5.

I have tried the GSO 30mm and although it is a capable EP I went with the 30mm 80deg Andrews EP in my f6 , but you might find at f5 the outer field bothersome , so stick with the GSO 30mm.

Ask Iceman what his thoughts are on the Andrews 30mm 80 deg as he has mine at the moment to try it out in his f5 .

Try the GSO barlow with the 30mm to give you a comfortable 15mm. The GSO barlows are pretty dam good as well , for the price.

I have a 1rpd eyepeice 30mm f/l. It's great in my f/10 C8, but might be a push too long for f/5. I would think you'd want to stick to under 30mm in f/5.

I can vouch for the 30mm as I have one in a f5. all the reviews come back positive on it. I have writen a very amateur review in the equiptment forum :).

I did almost go for the 1.25 15mm tho but went for the 30mm in 2 inch instead... glad i did. :)

they have a cheshire collimator for $45 there that works well to if you need one. :)
