Baader Morpheus eyepieces

[MortonH]

Looks like Baader have a new line of eyepieces. Kinda like LVW's on steroids.

I wonder if they're paying royalties to use the term Morpheus to the film company..

seems like they are responding to the new vixen ep's - they cant make a lvw clone anymore [as they're not in prod.] in the hyperion so have upgraded the fov -still a tad less than the new vixen

[PlanetMan]

Judging by the spec's and FLs these look to be Delos clones/copies

"the field remains flat and in focus, even in short focus telescopes."

Not an encouraging thing to say. In reflectors or refractors or both? Very different focal plane shape in each, and most Baader eyepieces are not Newtonian friendly...

Such comments are misleading, even contemptuous of the public. Why can't manufactures just be fair dinkum and say whether their eyepieces best suit Newtonians or SCTs, Maks and refractors? Newt's have a different focal plane shape to the other three, and very, very few eyepieces will do well between the two different shapes, little lone the huge range of focal ratios on offer too.

I guess time will tell, again, how fair dinkum their claims are...

Is it just me or are they styled to look like the Docter eyepiece?

[Don Pensack]

Their design was penned about 5 years ago, so not a copy of the Delos.
Also, radically different glass types.
Eye relief is different in every focal length.
Focal lengths: 17.5, 14, 12.5, 9, 6.5, 4.5mm
These are designed to yield no vignetting down to f/4.
[note: that doesn't mean no induced astigmatism or other problems. They still need field review from experienced users.
I've see a perfect eyepiece with unfortunate Edge of Field Brightening, so you never know.....]
Any intelligent mfr makes the focal planes as flat as possible to work in as many scopes as possible.
An eyepiece is more likely to encounter a strongly curved focal plane in a refractor than in a dobsonian, but an eyepiece designed for one wouldn't work well for both. That's why more eyepieces are fairly flat.
Some expensive eyepieces, though, do not have flat fields, so it shows that the pairing of eyepiece and telescope really is determinative of optical results. A classic example is the Pentax XW, in which the four short focal lengths have a negative field curvature and the 4 longest focal lengths a positive field curvature. That most complaints about the longer focal lengths come from newtonian users isn't surprising. That the 4 shortest focal lengths get great reviews by the same scope users also isn't surprising.
Alex is right to suggest a little more info would be useful.
Since such info would impact sales, I won't hold my breath, though.

Morpheus is the "God of Dreams" in ancient mythology, so I don't think it can be copyright to a film:

Still it's a brave choice given the puns that could arise from that name, like being able to "see the One", etc.

As soon as I saw them ... Delos came to mind...!

but your right also .... Docter ' look a like ' .

I did a currency check today ... Euro against AU Dollar

245EU is $369.00AU at today's rate.

Thanks for the Link Morton....
