Light & Wide - Eyepiece Reccomendation

[Paul73]

Hi Folks

I am trying to find a relatively light weight eyepiece to pair with my f7.5 SW ED80 for wide field viewing. It needs to be of similar weight to my Baader Zoom (450g) so that I can swap between the two without upsetting the balance.

Any ideas?

The Type 6 Nagler is very light, much lighter than the Baader zoom.

Most of the 1.25" 82 degree eyepieces will be no heavier than the Baader Zoom. Finding a 2" wide angle thats around the same weight is somewhat harder.

Do you mean a wide true field or a wide apparent field?

I think the 24mm Panoptic is hard to beat on both counts

Sorry Shane. I would love to know the difference between the two (would like to know). 

When I look through the eyepiece, I would like to see a wide expanse of sky (preferably with stars etc).

The 24mm is a bit on the light side. However, the 27mm is smack on the money. The Zoom is 450g.

Cheaper ideas anyone?

The Maxvision 68 degree eyepieces are pretty good performers for their cost. The 28mm weighs 534g and costs £85 from First Light Optics.

28mm Maxvision or ES is a very good condidate, if you want widest possible 2" (46mm field stop), I think Skywatcher Aero is a good one, 525 grams on my scale (my heaviest one).

Thanks guys. These look like good options. I have owned MaxVisions I'm the past and liked them. The 28mm was a little bendy for my liking in the f4.7 Dob (pincushion). Would this be better in the f7.5 frac? 

I'll do some reading on the Aero. The ES version is bang on the weight. So that might be the one to go for???

If your focuser / diagonal can handle 2 inch eyepieces you might like to consider the 37mm from I.R. Poyser, at the following link.

I have one and it's everything the site says about it, well worth the £130.oo

Geometric distortions likc pincushion/barrel or AMD is in the eyepieces, and wiill not change by focal ratio of a scope.

True field is the actual amount of sky you can squeeze into the eyepiece / scope combo. Apparent field is the 'width' of the eyepiece - e.g. 50 degrees for plossls.

E.g. a 12mm Nagler has an apparent field of 82 degrees which is much more than a 20mm plossl at 50 degrees. However, the plossl has a slightly wider true field in the same scope.

Hi Paul.

I use a Skywatcher SWA 22mm eyepiece at 70 degree fov. Weight 590gm. The viewing quality is excellent and it compared as well as a nagler when a straight comparison was done. 

I have heard the 32mm version is not anything like as good though and cannot comment on the smaller sizes either

I agree with Steve, his 22mm was superb.

Weight wiae, 27Pan is excellent comparable to the Zoom, Optcally excellent too by the reviews I've come across. There'll be though, noticeable more pincushion in 27 Pan in 28MV, I'm afraid.

[scarp15]

Yes i'd second the 27mm Panoptic.

[Paul73]

I.R.Poyser?? They look fascinating. I might have to grab one of the Possles on looks alone!

Thanks for chucking something genuinely different into the mix.

Thanks guys

I might well be on the scrounge at SGLXI to try a few of these suggestions in my little scope.

Even I should be able to hold off buying for another 3 weeks. ...
