Has anybody had a Lanthanum eyepiece

[supernova]

Has any one got a Lanthanum eyepiece? they come from Orion optics UK, do they do what it says on the tin? can you help because I need to add to my order soon to upgrade. THANKS.

[Macavity]

I had a beginning collection of Lanthanum eyepieces: 4mm, 6mm, 10mm, 15mm... and an anticipated 20mm, but sadly finances interveaned. :-( Take note of the field of view - And "wisdom" suggesting slightly diminished transmission (I see a fair bit of pincussion distortion too) BUT they were certainly closest to the "does what it says..." thing. Orion UK seemed (sometimes) to have HUGE delivery delays and Lanths are cheaper at Telescope Services (DE). At that price, or S/H, WELL worth it? Even the quirky 30mm 2" 60 Deg is a fine thing. I do regret parting with any/all of these.

Hi Chris Thanks for the tip on price just one of the lanths cost more than my first 6in newt + mount :shock: would that be the LVW-WEITWINKEL OCULARE ?

[Macavity]

Yeah, TS are quite easy to deal with (Email in English! etc.) despite slightly odd (Paypal etc.) methodology. (See their HOME page) They deliver small items with the working week usually...

The STANDARD Lanthanums are the "LV Okulare (langer Augenabstand)" or even:

I've got the 4mm / 7mm / 12mm / 18mm / 25mm and 30mm Lanthanums, along with the 5mm and 13mm LVW's and I like 'em all.

My god Lee how much did that lot cost? :shock:

I have a 12mm and 4mm and will probably sell them. They are very well made and perform very well, but they are designed for people who have to wear glasses - hence the long eye relief and narrow field of view. Also, you can't use Barlow lenses with them because Barlows are built into them. That's how Vixen manage to keep the eye lenses wide even at high powers - Hugh.

When you decide to sell let me know. Cos I wear glasses .

[moondog]

I have 5mm, 7mm, 9mm and 15mm Lanths. I rate them highly as I wear glasses.

Never heard the one about 'don't work with Barlows', as all mine do.

I don't have any lanths. But several of my firends who do wear glasses say they are worth the investment

I wear glasses and get on with the vixen LV's very well, I've the 7,9 and 15mm, I find they work well in the PST. Mine are all secondhand, don't tend to buy much new - it makes my money go further.

Dont ask... :? I wouldn't want to have to replace them all at once, that's for sure.

I don't wear glasses, but I still find the Lanthanums better than any Plossls I've ever used. Having said that, I've never had the opportunity to try any of uncle Al's creations...

I also owned a few. They are essentially the same as the Celestron Excel. Both are good for spec wearers, otherwise be aware of the drop in brightness, narrow FOV and pincushion distortion ... and that for the same price you can buy the Burgess TMB planetarys with 20mm eye-relief and 60 degree FOV 8)

..... otherwise be aware of the drop in brightness, narrow FOV and pincushion distortion ...

Does that (except for the FOV) go for the LVW's as well - only I'm quite interested in a 22 LVW at the moment

Haven't owned any of the LVW but I have looked through a few and was impressed. Worth noting that the Baader Hyperions are essentially Chinese copies of the Japanese LVW range so if you have ever looked through any of those you will have a rough idea of what to expect. I would guess/hope that the LVWs, being Japanese made, are a tad better(?)

[supernova]

Looks like need to spend some cash hmm thanks for all the help will look into it or through it

I'll PM soon - I have to go away for a few days.

But aren't Excels Chinese copies of the Japanese-made Vixen lanthamums? Masses of Vixen stuff seems to be copied in China. The Skywatcher ED80 and ED100 are apparently updated versions of Vixen refractors of about 15 years ago and EQ5 mounts look like almost exact replicas of Vixen GP mounts - Hugh
