I'm new on this list and just recently bought by first iOptron mount. Unfortunately my first experience was not too encouraging regarding the tracing Tue, 01 Dec 2009 09:17:51 GMT Brendan http://tech.groups.yahoo.com/group/ioptron/message/4921 http://tech.groups.yahoo.com/group/ioptron/message/4921 I think you just answered you own question Daniel. Using a drift align is the most accurate method of getting the ALt/AZ of the/any mount correct. After this Tue, 01 Dec 2009 08:39:30 GMT Daniel Jackson http://tech.groups.yahoo.com/group/ioptron/message/4920 http://tech.groups.yahoo.com/group/ioptron/message/4920 Thanks. These are all helpful suggestions. I have not checked the backlash issue--yet. Clarifications: First, when the scope has finally settled down, Tue, 01 Dec 2009 00:33:54 GMT nurserob2009 http://tech.groups.yahoo.com/group/ioptron/message/4919 http://tech.groups.yahoo.com/group/ioptron/message/4919 Just what i was afraid of. These scopes are plastic,cheaply made. I am told the focuser will barely hold an eyepiece let alone a camera. Should have known it Mon, 30 Nov 2009 23:18:42 GMT Brendan http://tech.groups.yahoo.com/group/ioptron/message/4918 http://tech.groups.yahoo.com/group/ioptron/message/4918 Hi Daniel a couple of things. I am reading this as either 2 possible things you are saying: 1. the scope drifts off when tracking a target (even after Mon, 30 Nov 2009 16:43:12 GMT Lou & Wes http://tech.groups.yahoo.com/group/ioptron/message/4917 http://tech.groups.yahoo.com/group/ioptron/message/4917 I've got a Celestron C8 on mine... mine's the upgraded mount- from Steve. Great combo! Wes ...

They all have the exact same description,nowhere can i find anything on their site about the Mon, 30 Nov 2009 15:24:24 GMT nurserob2009 http://tech.groups.yahoo.com/group/ioptron/message/4915 http://tech.groups.yahoo.com/group/ioptron/message/4915 Anyone use this for astrophotography? Can you post samples/ I am considering this but am worried these are cheaply made chinese scopes.

Now, it is also the case that there seems to be a bit of overdrift even during the process of centering the target.

The system is drifting (wandering off) after a "target sync"; or Its still has goto slew errors after a drift align, star Mon, 30 Nov 2009 10:12:27 GMT mikester http://tech.groups.yahoo.com/group/ioptron/message/4912 http://tech.groups.yahoo.com/group/ioptron/message/4912 Anyone out there have any expereince with this combo or a similiar arrangement? I just got the Vix. It is 14 lbs without the 2" star diaganol.

I have only one question about doing it this way. Admittedly I have the GOTO NOVA system on a Celestron EQ5, but I Mon, 30 Nov 2009 07:03:57 GMT Brendan http://tech.groups.yahoo.com/group/ioptron/message/4910 http://tech.groups.yahoo.com/group/ioptron/message/4910 Tommy...how does your set-up go with a 1 star align? Start with the basics. I found that 3 star align was a wasted feature. I found it better to do a drift Mon, 30 Nov 2009 06:23:16 GMT Christopher Erickson http://tech.groups.yahoo.com/group/ioptron/message/4909 http://tech.groups.yahoo.com/group/ioptron/message/4909 IIRC, there is a 1/4-20 threaded hole on the bottom of the ETX-90. There are some short dovetail bars and 90 degree angle brackets at Scopestuff.com that will Mon, 30 Nov 2009 05:12:24 GMT Jay Buckler http://tech.groups.yahoo.com/group/ioptron/message/4908 http://tech.groups.yahoo.com/group/ioptron/message/4908 So I have an older ETX-90 on fork mounts I want to mount for my second scope. Anyone have any idea on how to take the forks off & mount a dovetail on it. I
