Good to hear its working properly.
The LX90 really is a pretty accurate beast when set up properly
I learned if I slew past my local meridian to the western half of the sky, accuracy falls off somewhat; but a simple "synch" on a nearby known star
Again possibly due to the align stars you used. They were 60 deg apart in Az but both on one side of the meridien.
I try to get one each side of the pole for best results
for example, at 4am, i would have chosen say Phad and Shedir
I also learned leveling while important does not have to be perfect for visual only tracking.
I was able to level and setup, ready to observe in about 15 minutes.
Correct. The LX90s in altaz track by working out the Alt/Az for the current RA/DEC now() and a set time in the future. They use the align model to do this conversion, and then work out a motor rate required to achieve it.
As such, the align model assists in gotos and tracking.
On top of this,centring the target stars accurately also assist in the align model
How do you do it?? ie xhair EP, or just guess centre??
If tha latter, if you heavily defocus on the first star, you get a big donut and it is much easier to centre this in the fieldstop. Slew to the second star ( without refocussing ) and centre.
Once done, reset the focus correctly and you should be away.
