Hi, I want to buy a field flattener for my ZS66 APO. After reading the old posts about this subject I'm still a little bit uncertain about which one is the...
It's nice to finally have something to post again. I feel that this is an object just made for this scope! A bit of guiding issues early which you can see in...
Hi Larry- Nice shot! I have the same set-up. 66SD piggy-backed on an LX90. I guide with PHD and a DSI-Pro, too. I have found that if I reduce the LX90 with...
Thanks Derek. It's a nice system, in my opinion. And, yes, I use the .63 FR as well. Also gives a bigger field for more stars. Have you gone the other way...
very nice. One thing I figured out recently using a vid camera and laptop for autoguiding, before I start shooting, I watch the tracking error rates on the...
I tightened the inside set screw, and now the focuser holds and will travel inward when pointing at the zenith. One of the allen wrenches provided with the...
Hey Larry- I agree: it is a nice system. I was getting 10min subs at a dark location that were perfect (although without a decent flattener for the 66...). I...
Do a search on the posts. I believe someone tested a FFIII with the ZS66 and was happy with it. With the ZS66 I am not sure if you will see a big difference in...
Hi Paolo, I have the 66SD, and the WO FF/FR II. It was recommended to me as I wanted to take digital shots with the scope with my Canon 350D. I've only had a...
Thank you both for your suggestions. Kurt, I probably should do a better polar alignment--right now I do a fairly rought iterative alignment. And, Derek, I...
Hi again, The set screw affects only the tension of the steel bar that turns the focuser tube,and 1/8 turn is probably about right, it usually doesn't take...

Thanks Timm! A couple of things I forgot to mention... The focuser is not ever so slightly harded to turn, it takes just a little more force at the large knobs...
Hi guys - been missing for ages due to weather and work. Just posted a new image though - to my folder KeithT taken in September with my Megrez90 and guided...
Is there someone who can tell me when my Zenithstar 105 SN:059942 was made? Year and month maybe? any specifics? I was told it is an oil spaced triplet by the...
Wayne, I do not believe there is any correlation between the serial number and the date of manufacture. So I don't think you will get an answer to that...
Hi Robert, It's possible that it needs just a tiny bit of extra tension on the two speed knob, even though the large know is turning the focuser after you have...
Hello Group After talking to Daniel, the group manager, I am delighted to announce that The Imaging Source is running a competition in which you can win one of...
Thanks to Morton & everyone else for their help. At this time I will consider my options. I'm thinking I will go for the FLT, but it means waiting a bit longer...
The ZS 105 were produced in 2005 (with pre-production samples starting in late 2004/early 2005). They are air spaced, no oil.. The lenses were produced in...
Thanks for all the replies... I appreciate them. I love my ZS-105 every since William collimated it, it gives great images. I am planning to use it as my...
Is there any way of upgrading a ZS110 to a FLT110? Geoff ... remain for awhile. I think many found the ZS110 focuser a little light for imaging. The ZS110 and...
This is something I've also thought about. It seems to me that you would have to: 1. Put the Vixen flip mirror into the 2" focuser tube of the scope. 2....
I would seriously look at the Borg Helical focuser. More precise than a R&P IMO. http://www.barrie-tao.com/vixen80ss.html Ciao....Barry ... upgrade ... ...
Geoff, we could sell you just an FLT tube, but then you would still have a problem, because the lens cells threads are different, even if the glass inside is...
Hi Wayne, ok now I remember your case! Mmm, I am not sure who sells R&P focusers, sorry.. What do you mean by, better control? ... upgrade ... Instruments ... ...
