WO Game Changing Astrograph?

Seven lenses? Theyre turning into camera lenses.

I looked on Facebook and WO have said the Cat61 will have the same Petzval design as the Cat51. Focal length is 300mm.

Did I interpret correctly, that this WIFD moves the main objective lens cell, rather than the camera in a standard scope? At least that is what i saw on the schematic move representation.

Thinking about it, its a good attempt to stabilize mechanicals like a camera lens, but I wonder how the objective movement is guided to parallelism, since similar considerations were always important for drawtubes in classic focusers...

Here is a video of the scopes from NEAF.

The Pleiades scopes are 68mm and 111mm, but no focal length or f-ratio is given.

Interesting. I like this WIFD development, very clever solution to a genuine problem with focusers. The 7 element 111mm will be their version of the TS and Tecnosky flatfield 110 mm f/4.8 scopes. The tecnosky is the 7 element design, with front collimatable cell, and same overall construction as the TS CF APO (blue and white) and the tecnosky owl series, but at >3700 EUR. WO version with the WIFD in that scope I'll bet (with WO premium costing as usual) will be north of 4300 EUR.

Pleiades 68 is fl 258 / f3.8 from this facebook post:

Both look interesting, but 2024?!?

An unboxing of the Redcat 61.

Advantage with this design no stress on focuser . BuT as it as been said what's wrong with the normal focuser. I have two W O scopes a 103 and a 81mm and I have never had any issues with the focuser. I will wait for review results.

Depends on your imaging equipment. Its supposed to eliminate tilt, my Z61 struggles a little with the weight of my imaging train (you can feel it when doing fine focus adjustment), I'm sure it introduces tilt but I don't pay attention to it much.

First rewiew is in

Is electronic focussing possible?

Yes. It says the scope is compatible with EAF on the WO website.

Looking like there's a chance they'll be out end of this year.
