Hi - I posted this link on the WO Facebook page as well and thought Yahoo Group
members would enjoy it.

http://www.flickr.com/photos/hojong/5488442255/

It is the Horsehead Nebula taken with a new WO 151mm Astrograph refractor.

Sorry - I don't have more details on the new scope, but hopefully WO will
announce details soon.

Enjoy

Hi - I think it will be soon.  I have the DDG focuser now and am testing it now
and so far it is a very nice focuser.   Besides the nice DDG part of it that
will be useful for photographers, the actual focuser is smoother and more robust
than the original crayford style.

I have started writing a review and I will include a comparison to the original
WO Crayford with 2-speed upgrade, and the WO SCT Linear Power focuser which I
also have.

I plan to do a video review of it as well, once I have some time and it's not so
cold outside.

I think it will be a worthwhile upgrade for many.

Hello Everyone,

The New 151 APO has excellent design for astrophotograpy with 5 element in two
group (it's air spaced FPL53 element) it cover complete full frame CCD.The scope
will take pre-order only.intruducing price is US$7988 for OTA (first 3 sets
only) that includes new 3.5" DDG focuser and mounting rings
delivery time takes 2-3 month.
Thank you.

Hi, Just wanted to let everyone know about the first class customer service I
have received from Tim at WO. It has been a real pleasure to deal with such a
helpful, patient, courteous and obliging member of the WO team. Much appreciated
- thanks very much !

Hi Dan,

Thank you Dan,the 151 is the first sample  we made,the reflection spikes was
from some tube threads of rear element ,the final version will be improve for
sure.

Hi Friend,

Mr.Lin HoJong just share me another excellent photo he took last week.
here is the link: http://www.flickr.com/photos/hojong/5493679594/
Thanks to Mr. Lin.

William

Hi group,
   i�m a very proud owner of a FLT-98 DDG OTA and in my opinin, the perfect
refractor in its range, well finished and very high quality lens.
   As i do remote astrophotography, i�m looking for a motorised focuser or
another solution that fits to the FLT98 DDG and easy install.
What ideas o products do you recommend?.
Regards from Spain

Miguel Angel Lazaro Balaguer

I've just fitted a lakeside focuser to my FLT-132(with feathertouch) and I'm
very impressed. It is ASCOM compatible and so can easily be operated
remotely...and because it uses a serial connector can operate Orr great lengths.

Michael Gossage

Dear W.O. /Tim,

I bought your 110 FLT Triplet APO in February 2011, but only recently (7 March),
I was
able to celebrate "first light" with my new telescope. This is due to the
current poor weather conditions in the Netherlands......

I had read several reviews about it before I bought it, and I was very keen to
have my own experience.

I find the quality of your product extremely impressive, and I am (still today)
somewhat speechless about what I saw last night: M44, h+chi Per, M67, M42 never
seen before in such a crisp and sharp quality and, as far as I can judge,
outstanding imaging performance. I am very pleased with the incredible optics
and perfect mechanical engineering.

Best regards

Chris

If it is the current model M90 (2010-on) Yes the flattener will work.
If you bought a second-hand earlier version M90, no it won't.
Not sure what you mean by older type? P-flat3?

I got ripped-off when I bought the AFR-IV/P-Flat4 as it was advertised as
suitable for M90... now they don't include M90 on their site, but they do on
WOnline where it mentions "M90(2010)"

WO's scopes are great.. but their websites are full of dead links, non-existant
product(compare their two sites) and false information.
Worst of all, their products go through version changes but the name stays the
same. How hard is it to call the Megrez90 MkI, or MkII or MkIII?

They realy do need to lift their game to eliminate confusion.
That has not happened in the last 3 years though, so I'm not holding my breath
and I'm not buying WO products.. it's too risky.

Christian et al.

I have fitted a Skywatcher focuser and a Shoestring USB controller on a FLT132
equipped with the WO/FT 4" focuser. The operation is very easy and the device
works great.

I have posted photos (folder is "132 mm FLT with Skywatcher focuser" in the
photo section).

Since I took the pics, I have painted the silver bracket in black and replaced
the small allen screw that tightens the motor to the focuser axis by a bigger
one that allows a quick disconnect, mainly for moving the focuser by hand
through the opposite knob.

Hope this can help some.

Hi all.

Has anyone put a webcam behind a Powermate 4x on a FLT132? I am struggling a bit
with the focus issue. I have tried extensions before and after the Powermate,
then both. No way. Webcam is a TouCam Pro II, naked (no lens).

Ideas welcome.

Best regards.

Hi Jean-Marie,

I am not sure that it'll work (although I did not try the combination 'naked'
webcam + powermate/Barlow lens).

What will work is the webcam (without lens) in the prime focus (no powermate),
or, powermate + eyepiece + lens for the webcam, i.e. the so-called "eye-piece
projection" method.

Chris

Hi,

I want to know what is the diffrance between we-flat-2 x0.8 reducer and the
newer version we flat 3?  in wo website thare is no diffrance in specs...

I have an orion 80ed and i'm using version 3 and i don't get good results...like
field rotation in the sides and stars like about to explode...

Anybody knows where can i still buy the we flat 2 ??? :-(

thank's!!!!!!

Chris, many thanks for your response. I was pretty sure though I had done that
once but my memory may not be reliable.

William, thanks for that. Scopes are different indeed but I would still
appreciate receiving details on your setup re focus, i.e. distances and eventual
extensions you're using.

Kind regards.

I found the solution and the right adaptor's configuration. William you're
right, focus is tricky and has to be tested during daylight.

Matter closed, thanks.

I've finally got around to running some of my images through CCD Inspector and
thought i'd share with you all the output.

http://groups.yahoo.com/group/William-Optics/photos/album/3215557/pic/list?mode=\
tn&order=ordinal&start=1&dir=asc

One thing I have noticed is the improvements that the feathertouch focuser has
had over the original, and also an improvement in field flatness by machining a
spacer to ensure an accurate chip to lens difference for the TMB flattener.

Can I ask two questions though:

Firstly, I have assumed that the TMB flattener does just that...it flattens, it
doesn't change the focal length.  Is that correct?

Secondly, does anyone have any suggestions how I can get this field even
flatter?  7-10% field curvature seems like a lot to me!

Am I just worrying too much?  Is this where temperature of the setup will start
to have more of an impact?

I look forward to hearing from you all.

BTW, if williams wanted to send me a new DDG to compare with this set up I'd be
happy to post some test results up.

Cheers,

Michael

maybe it would benefit from a small sub-aperture mask?

150mm is quite a lot of glass for f5.2.

I would love to get hold of one of these beauties....someday maybe...someday!

Keep them coming though guys...if I ever win on the lottery I'll come and pick
it up in person!

Best wishes and clear skies

Michael

William,
    the 151 looks like a promising scope. Will you have it at NEAF? and will you
have any to see at Neaf?

William hasn't posted official specifications yet, but I believe it is a special
5 element design.  My guess is that it incorporates a built in flattener/reducer
of sorts, which allows it to operate at F/5.2 and produces such a nice image
without the field curvature inherent in standard refractor designs.

is that a feather touch focuser on the new 151mm!!!!
If it is and the field is as well corrected and flat as the picture taken this
scope is a home run!!!!

No idea if a Feather Touch will be included or available yet.

If I get any more of the specs from William I will post them.

It does look to be a very well corrected and flat image from the ones posted so
far from this early model.

Hi,

I am quite new on this forum,
Being owner of a megrez 88 for one Year, I was almost satisfied.

But I noticed that when rotating the focuser, the star that I centered in the
eyepiece, was shifting a lot ...
I discovered some play in the rotating focuser, and searching on this forum I
saw that I have to take care about the 3 screw around the focuser, not only the
one to block it.
I tried to recover the alignment, but I did not succeeded... so far.

Any idea, abut how to manage this issue ?
What about the other screw on the focuser ?
How to proceed for good alignment ?

Best regards
Thank you for any help
Sorry for my french english...
