Hi Steve, Thanks for your input. Every opinion is welcome, pro or con. I use the Zenithstar 66 SD and color is not a problem at low, medium magnifications. It...
I just so this focuser on the William Optics website. It can be fitted to Synta-type refractors, in place of the stock focuser. Neat. Has any of you ever tried...
Hi Don, Thank you! Yes, I am sure the FD is very good scope. If I had the money, I'd go for it without hesitation. I still don't know how much it costs in...
Thanks everyone for the replies. I'm looking to bend the light 90 degrees so I won't be using a 45 degree diagonal. Since the 80mm ZSFD is f/7, I'm guessing...
Hi, this is the final result of the project I began 2 year's ago: catch all the Full Moons month after month to realize an animation showing its librations and...
Hi Scott, As far as I can see both scopes have the same baffle, so I don't know what caused the masking. Consequently, I would check any ZS scope for masking,...
On the WO comboplate, there are some holes that are properly countersunk from underneath, allowing you to screw into the scope from the bottom of the plate and...
Hi Joe, The Megrez Super APO is vastly superior both visually and photgraphically to the ED II. I own both the Z80FD and the M80A (Super APO). Visually I find...
Laurent, That is long commitment with a great result. Have you tried loading the images into a blink comparator to identify an new craters or markings? danny...

Hi Dan, ... No, because the individual images are not good enough to discover new small features. The Megrez SD is only a doublet (strong chromatism) and the...
Hi all, Boy I hate these spammers! I deleted all the spam this morning and immediately banned the user. I think we need to consider changing our member...
I honestly don't think you have much of a choice. It's incovenient for first time users, but it's the price we have to pay to prevent these sorts of abuses by...
It is a shame that that becomes necessary, but I don't see any alternative. There will always a few who insist on trampling on others to pursue "personal...
I think member approval by a moderator would be sufficient. If you require a small bit of info as to why the potential member would like to join, then you can...

Yes, they had the same problem at the "Uncensored Tak Group" and I guess they moderate the first mail of new members. It has elliminated a lot of spam up to...

Hello Again and thanks for the information. I plan to do more research and perhaps see what's available in the 80mm or 90mm range. Seeing there are a few...
Yes, please do. ... From: Timm Bottoni To: William-Optics@yahoogroups.com Sent: Wednesday, May 02, 2007 6:48 AM Subject: [William-Optics] I hate SPAM! Hi all, ...
Sky and Telescope's review of the Megrez 90 says that the baffles reduced the aperature to 87 mm. Is this true for the test scope only or a characteristic of...
Hi David, I owned an 80mm WO ZS II ED that had a masking problem, WO was kind enough to let me upgrade to the FD for the difference in price. My suggestion...
