Jon,

As the review, to which I linked, states.

I didn't think the old 18mm 82° 1.25" was very well corrected at the edge, either.

When you push the limit, sometimes the compromises made are questionable.

I just picked up a 40mm Maxvision from APM. Fantastic eyepiece in my 120mm Skywatcher, I think it gives me about 23X. 

 

Anyways I really want to decloak mine, and I've done this before with a 7mm Celestron Luminos. However the only downside I have found is that I can't seem to find a decent rubber eyeguard for the Luminos. Does anyone have a specific eyeguard that they know works well with the 40mm Meade/Maxvision?

I use a 49mm lens hood on my decloaked Maxvision 40mm. Works great!

Excellent. I removed the plastic ring insert and a 55mm plastic end cap fits the top well. I can't remember where I got it but the 53mm one from Agena would probably work. http://agenaastro.co...p53b-black.html

Would these Meade eyepieces really beat the ES 68° ones on and off-axis in terms of sharpness?

 

Optically,  the ES 68's and the Meade Series 5000 SWA's are reputed to be identical.  One night I spent some time comparing the 24mm's in my 4 inch F/5.4 Televue.  The skies we're dark,  lots of stars,  lots of contrast.  To my eye,  they appeared identical , they were even perfectly parafocal,  no need to refocus when switching eyepieces. 

 

I did find the bulbous twistup eyecup objectionable.  I have the 16 and the 24 mm and I hardly ever used them until I removed the eyecup.. That night,  I started using them and I haven't stopped. 

 

Jon

 

I did that with a pair of 20mm and now they fit in my binoviewer. Picked up some cheap rubber eyecups and they work great!

I placed a Televue eyeguard extender on my decloaked Maxvision 40mm with double sided tape, perfect eyecup to accomodate its eye relief

Double-sided tape holds this Dioptrx onto my Meade 34 mm. The TV eyeguard extender is just like a Dioptrx, but without the lens.

I had a chance to try out my 40mm MaxVision with the 120mm SkyWatcher. Wow what a fantastic eyepiece in that scope and I got to see 41P/Tuttle-Giacobini-Kresak with it on Saturday night.

 

I did try it out in a f4.5 Newt and it was crummy, but in the refractor it was great.

I also decloaked a 28 mm 68 deg Maxvision. I'm still working on the 16 mm Meade 5000 SWA and the 40 mm 68 deg Maxvision I recently bought as exhibition leftover from Bresser Germany. This will provide for a nice, lean, wide angle eyepiece set for an excellent price/quality ratio. The 16 mm Meade I once took over in almost new state for EUR 80,- years ago, the 28 mm Maxvision was for a few years also on sale for about EUR 100,- (new) and the 40 mm Maxvision I recently bought in absolute new state for EUR 125,-. The set of 3 wide angle eyepieces cost me only a little over EUR 300,- in total.


I always liked the optics of these eyepieces, but never their weight, size and the uncomfortable way you have to place your eye on it. So it was no hard decision to decloak them. I let the pictures about the decloaking speak for themselves, now.

This can be done for all 68 deg 3 eyepieces: the Meade 16 mm 5000 SWA, the 28 mm Maxvision and the 40 mm Maxvision.

The 28 mm 68 deg Maxvision has an ER of 21,65 mm. The eye lens is about 4 mm thick so it is 2 mm till the middle of the lens. The lens is a concave so you need another 5 mm from the center till the top flat of the decloacked eyepiece. From the top flat of the eyepiece 21-7 = 14 mm is left to reach your eye.

With an Agenta AstroProducts rubber eye guard (28.4 mm ID) this will work. It has a 13 mm hight, with almost no pressure on the rubber my eye reaches the desired ER.

_

IMG_20170514_222621500_zpsyijlroul.png

 

I'll make the eye guard detachable. Some work for the lathe.

_

IMG_20170517_214347120_zpslnzwbvxo.png

 

I can unscrew it by making some fine thread in a 1.2 mm thick aluminium plate.

_

IMG_20170517_214434470_zps37bmq7ag.png

 

The plate is glued on the eyepiece with some thin double sided tape and blackened. Rubber grip tape is glued around the eyepiece to prevent it from getting to slippery when dewed over (wet) and prevent it from easily rolling away when laid down.

_

IMG_20170518_195245837_HDR_zpstult29la.p

 

The eye guard can be unscrewed making this eyepiece also comfortable for observers wearing glasses. I glued a felt ring on the aluminium plate for this.

_

IMG_20170518_195337064_HDR_zps9pdstcl8.p

 

With the rubber eye guard on, star viewing is far more cofortable than it used to be. The whole widefield is vissible with a sharp fieldstop edge.

_

IMG_20170518_195254946_zps0rlddkfp.png

 

The weight is reduced from 515 gram to 395 gram (-23%). The size is reduced from 69 mm diameter to 55 mm (including rubber grip tape -20%). The viewing is comfortable and providing the whole 68 deg widefield, with glasses or without.

 

One lean, widefield eyepiece done, two more to go.

 

Robert.

When I deshrouded my Meade 5000 UWA 24mm, I cut off a section from the shroud to put back on the eyepiece as an eye-guard.  I wear glasses, so the wider, relatively low eye-guard works well for me.

 

But my eyepiece is a UWA, not an SWA.

No need for all of this. Just use the EP without the outer casing, very easy to use, unless you're a beginner.

Bob

yes they are very nice EPs

i believe i had all of them at one time

when they had them for clear out they were great deals

i believe they were like $60 a pop and i thin the 40 was like $80

there are better EPs out there but these are great for the money 

ES 68s are the same apparently i saw a bit of a difference and liked the meade swa 5000s better

Better? what is better? I've tried Panoptics, and I prefer the Meade or the ES. Better light scatter control in the Panoptics some have said, but who's looking at fairly "bright" things in a long FL eyepiece?

 

Unless, you're using an SCT and need the longer FL eyepiece for scatter control, I see no BIG differences.

I did that with a pair of Meade 20mm so they would fit better in my binoviewer.

The way things work:  Discontinue an awesome line and pump out a newer line that is inferior.

Well, they weren't discontinued.  The bodies got pared down, seals were added, and they became the 68° Explore Scientific eyepieces, without the overly-large eyecups.

If you mean Meade, yes, they changed factories, but there is no consensus the newer ones are poorer eyepieces, though they did drop the 68° series in favor of 60° and 100° series instead.

Yes, they were in fact discontinued as the Meades. You can't buy them new as the Meades, which IMO were slightly better than the ES versions, (darker backgound when looking through them, but the ES are ergonomically better). I still like my 28mm ES 68 now tho. Now they have some of them branded as Maxvisions.

This is of course a personal preference and should not be presented as a general rule. I myself don't wear glasses and really prefer a supporting and light shielding, rubber eye guard. This way providing for an optimal and comfortable eye position. My son does wear glasses, though, so that is why I made it easily detachable.

This rubber eye-guard fits the Meade 24/68 perfectly:

http://agenaastro.co...es-id-48mm.html

 

I don't always use it, but nice to have when there's a lot of stray light. Here it is on my de-cloaked Meade.

Lack of scatter would help in picking out the nebulosity in the Pleiades.

 

 

Unless, you're using an SCT and need the longer FL eyepiece for scatter control, I see no BIG differences.

Actually, there probably isn't a big difference in scatter, regardless of scope. From what I hear, they're all pretty good, so I can see why you might prefer the Meades or Explore Scientifics.
