LX90 LNT Question

OK.........I broke down and ordered an LX90 with LNT and upgraded coatings.......does anyone have experience with LNT? Does it work as advertised leveling the scope and aligning to True North?? Does it work better if the scope is level and pointed north already?

Any real experience comments on this feature would be appreciated.
Thanks,

Howdy:

It works just as avertised, I'm rather impressed by the LNT system.

As for "Does it work if it's level and pointed north already?" Well, you really don't want the scope pointing north when you start. A little off true north is best for starting out in my experience, but I'm not sure that really matters. There's no home positon required for the LX90 (unlike the LNT ETX). You lock the locks, turn on the power, and the scope will do a little dance, figuring out where north is and where level is.

Do note that, naturally, the first time you use the scope you will have to enter your location, time, time zone, etc. Thereafter, the LNT will keep the date and time current via its onboard batter-backed clock.

I have a LX90 LNT.

It does help to get the tripod head fairly level though it doesn't have to be perfect.

If the scope is way off (like 10-15 degrees) the first alignment star thats normal and nothing to worry about. Just center it up and hit enter.

Watch out for your cords. Even with the cord wrap feature on your power cord can still get snagged on things.

My first time out with my scope it took me 20 minutes to get it aligned.
Most of that time was getting familier with the autostar controller.
Now that I'm familier with things it takes about 4 minutes.

At star parties I've walked away from my scope for 30-40 minutes and the object is still in the (wide) field of view when I came back.

Once aligned you're going to have ALOT of fun !!!
