Hi Andrew
Seems like almost a month since I updated you on what I did last with the scope in trying to resolve the non-tracking issue. I re-trained the drive at least 5 times but I still haven't been able to resolve the issue of it not tracking the object when I use the arrows to move to an object, after the telescope has GOTO'd to something.
I have a question which you might be able to help me answer. I know that since the stars/constellations/galaxies are so far away, that their actual movement, relative to us, can be taken as negligible. In this case, the perceived movement of these celestial bodies is due to the rotation of the earth. However with the solar system objects, they are closer so their movement is noticeable, hence their movement across the night sky is actually a combination of the earths rotation and their actual movement relative to earth?
Now if I GOTO to an object and then use the arrow keys to move to another, I assume if this other object is not a solar system object then its movement across the night sky will just be due to the rotation of the earth, in which case if the telescope tracks on sidereal mode, it will keep the object in the field of view. However, if the object is a solar system object, then its movement will be not just sidereal but its orbit as well, in which case if the telescope is tracking just sidereal, it won't be able to keep the object in the FOV unless it knows what object it is? Please correct me if I am wrong since I am just blabbering out.
However since the LX90 has got a lot of objects in its database, one could expect that as soon as the arrows have been used to get to an object, the LX90 will search its internal database to find out what object is currently in the FOV (using the RA and DEC) and then use the appropriate tracking speed to keep it in FOV?
Can you please do me a favour. Assuming you have a LX90, can you please GOTO Saturn. Once there, use the arrow key to move just one step any way or maybe just bring one of the moons into the centre of FOV. After doing this, do you see Saturn and its moons start drifting out of FOV? Assuming that it takes x seconds for your LX90 to correct itself, after x seconds, do you see Saturn and its moon return into FOV and the FOV show what it showed when you had used your arrow keys to go to something else?
Thanks mate and hope your weekend has been great.
