Just got my handset back from being reprogrammed so had my first night out using goto (was just manually guiding it before)

I noticed that on 2 star alignment I could get it accurate enough to land stars in the middle of the 10mm E.P. for a short while But after a few slews the accuracy was off by a bit, then I went back to the alignment star and the accuracy was off by a mile and got worse with every other slew after that. The temperature dropped well into freezing so I?m wondering if that seriously affected the battery life and caused the errors.

Also is there any Internet sites that will tell me my Long/Lat co-ords in the UK?

As a bit of a gripe im annoyed at the maximum slew speed. When your trying to align to two stars that are far apart Slew rate 9 seems to take forever to turn the scope through 180 degrees, I wish there was an easy way to just disengage the motors so you could point it freely by hand not just for aligning but when your fed up of the GoTo fudging up you can just guided it freely :/

Hey, if you're getting the objects ANYWHERE in the fov of a 10mm ep using the 2-star align, count your blessing!! For your initial goto, you should use the 25mm ep(40mm ep, if it's an older Nexstar SCT). I can get my Nexstar 8 aligned close enough to use the 25 rather than the 40, but the manual calls for using the 40, then increasing mags. Clear Dark Skies!!! WW

Hi James,

Your problems (missed GoTos and slow speed) are very likely power supply problems. AA batteries in the cold will have those effects. Read the power sources article in the Odds and Ends section of my web site (http://www.NexStarSite.com)for some ideas. With ample power you will find the slewing speed during a GoTo is quite brisk. Still, if you take a little time to plan in advance (might I suggest the latest version of NexStar Observer List available at my site), you won't find yourself slewing back and forth from one side of the sky to the other.

For a site with your long/lat:
