Hi, I have reviews posted on Astromart and Cloudynights describing the WO UWANs and SPLs in my Megrez 80FD (same scope basically). It's a tough choice unless...

To any William Optics Rep: Any update on the Megrez 90 shipment date? I was told by the dealer I bought it through that it is yet again delayed until...
Hi Tony, Actually I used both of the brackets that came with the Robo. I tried using just one bracket and it was not stiff enough under the load of the...
Hi Matt: This is really helpful to know - I'll also glue the two brackets together after bending them. This is going off topic a little, I can't seem to see a...
yup, that'll do it, glad you found it so quickly! Matt ... From: tony8fs To: William-Optics@yahoogroups.com Sent: Friday, August 22, 2008 11:37 AM Subject: Re:...
... Paul, Take a look at my FLT-132 with a Robofocus mounted on it. http://www.flickr.com/photos/hojong/2058809519/in/set-72157603311318887/ Hojong Lin...
Hi, as I had my lens cell out of the scope for cleaning (easier when I can lay it flat on the table) I figured why not take the focuser apart as well. That...
I've found replacement bearings here: http://www.vxb.com/page/bearings/PROD/3mm/kit860 When I put things back together I put the broken bearing in the back. ...
Hi Sander, Does your rotating ring have the nylon set screws for setting tension? If so, then tightening them some will stiffen it. Or you could replace them...
Hi Flyod, I see a few (2? from memory) small metal grub screws in the gold ring with angle indicators. I haven't touched those. Let me see if I can secure the...
Hi, I have a few pictures here: http://gallery.tungstentech.com/main.php?g2_itemId=802 No pictures that show how to remove the focuser knobs, that's described ...
Hello All, It has ben a while since I posted last, but here is my latest image with my 66SD. I hope you like it... Imaging Scope : William Optic ZS66SD + WO...
I modified my 400D Monday night and had a quick opportunity to test it out last night before the clouds came in. Here is a short stack of IC 1318. I really...
Thanks Kurt. It was a bit nerve-racking, but, was not all that difficult to perform. The results were well worth the risk! David ... expensive camera!) ... it...
Today I received a new William Optics FLT-98 for testing. I'm going to be using the telescope over the next 2 months for imaging, I'll produce a full review...
Hi Matt, You might want to get the field flattener. It's a great scopes (I own one) but it suffers with vingnetting using the Canon DSLR's I have taken this...
Hi Paul, Nice image and the scope looks great in the setup, she's a real looker that's for sure. The largest CCD chip I'll be using is the one in the SBIG...
Hi Paul, as I understand it flatteners don't fix vignetting nor illumination curves. They attempt to make a curved focal plane flat, hence the name ... ...
Hi Sander, No I don't think you are full of it :-) Maybe I'm getting a little confused with Coma? Any how this is an un-cropped Raw frame converted to .jpg ...
Hi Paul, I'm glad we can have this conversation as I think these problems cause many of us trouble, especially now that we get larger cameras. With my old DSI...
Guys, All optical systems exhibit coma, it isn't reflector specific. These days we use short focal length refractors for high power observing and wide field...
Sander, I'm a little rusty, but there are seven--I think I recall--classic optical aberrations (Seidel aberrations). Optical designers minimize them. For a...
Just did a little checking: there are 5 (vs. the 7 I wrote earlier) Seidel aberrations, and chromatic aberration isn't one of them. The Seidel aberrations are...
