I would appreciate advice on lens cap. After using my telescope in cold weather , when I return home should I leave the lens cap on or off as it warms up with...
Have been a member for over a year. Started with a Zenithstar 80mm,which now is sold . Received a Megrez 90mm several months ago. I am enjoying it much more...
Thanks to everyone who responded. IT was exactly what I was looking for. In the end I got an offer on the LXD that I couldn't pass up and I am very familiar...
none of the current wo scopes utilize flourite glass, so any labeling issues may be a conscious decision by wo maybe to correct any previous labeling ... ...
Happy New Year! Hi, just to be clear, it is FPL-53 glass as are all of their "fluorite" scopes are, I believe, but I'm not sure what you mean by the "rear...
Dan I do not understand your reasoning. As long as the lens is dry I would put the cap on. This will keep "dew" from forming on the lens due to the warm humid...
Rod, Thanks MUCH for the feedback and my wife & I look forward to your formal review of the M90 APO. It's been a number of years since I've been really active...
William, I have the WO Megrez 80II SD and 90 APO and live in New England (prone to cold moist nights). What I have found to work best is to take my equipment ...
Anyne have experience using the current WO 2-speed crayford focuser? If so, how smooth is it and are there any "rough spots" or inconsistent resitance while...
Let me correct you. It DOES utilize fluorite glass, a.k.a. FPL-53 by Ohara. It does NOT utilize CaF2. Due to different opinions on the subject, we have stopped...
Now see what happens when I don't frequent the groups I'm a member of!? I thought I had followed up on this, but it would seem I forgot. In short: 1. A...
I wanted to follow up on this because I discovered that I had forgotten to do so. This post is pretty much duplicated in another thread. Please email me if...

Any advice on mounting a RoboFocus to a ZS80 FD? Attaching the motor to the focuser shaft is no problem, but what bracket option/configuration have others...
Just an update to my previous post regarding the 0.8x reducer that gave a lot of distortion for the Orion 80ED (I tried all spacings from the 300D (Rebel) chip...
Hi Andrew, Thanks for posting this update! I think all of those cameras you mentioned have the APS-C sized chip - 22.5mm x 15mm - like my 20D does. But other...
Hi, Doh! Never mind - I see from the new pictures it attached directly to the T-Ring - what was I thinking??? If you can post a pic of the daytime sky, it...
... Here you go - not a daytime sky, but a nightime stretched image. It was a high moon and only 30s shots hence the lack of stars and bright background. The...
charlie the wo focusers that are included on their scopes (flt132 rack and pinion and sd 66 crayford ) and their after market replacement crayford focusers are...
Chris, Get a Takahashi TOA/TSA 2.7" reducer. It works perfect at least to APS size format for which I tried it on the FLT110 and gives f5.3. You only need...
Ouch, indeed, that is TERRIBLE vignetting at this format of sensor. It is more like a peephole :( You could try with flats, but ok, that always gives quality...
Hmmmm... don't hang a heavy STL to the 4 inch FLT110 focuser without first thightening the *hex screw* underneath the focuser. You may be in for a surprize if...
... Hi Dodi Thanks very much for the tip, I appreciate it. I have both the Celestron 6.3 FR/FF & The Sky90 FR/FF. I have the Antares 2" sct to t-thread adapter...
There is indeed vignetting, as Andrew and I have discussed it in another forum. Bear in mind though, those pics are stretched, the raws don't show nearly as...
Hi Chris, The FLT110 field flattener works well with an EOS 5D full frame, but it gives vignetting. Not by the nature of the flattener, but because William...
