Hi
I am located in Sydney and I have been trying out my new HEQ5PRO mount the past few nights. I am having trouble with its pointing accuracy especially on initial two or three star alignment. For instance after choosing
the first star Alpha Centauri I find that the mount stope slewing way off - almost 3/4 of the way to Beta Centauri, which is a long hike to correct with the movement keys. However, the coordinates shown on the paddle are correct for Alpha Centauri.
I have checked my initial setups carefully eg location,timezone, date, time etc but these are OK. Also I have carefully polar aligned the mount.
Do you have to start alignment with the scope in the parked position? Should the RA shaft be vertical and the DEC pointing due South for this to be correct? The scope seems to park with the RA shaft noticeably off vertical. I have followed the instruction book carefully but I cannot fault my
procedures as instructed.
How close can I reasonably expect the mount to point? - I would hope to be able to see it within the field of my 25mm crosshair eyepiece in my 80mm f6 finderscope.
Is there a preferred way of setting up for star alignment?- I seem to be
missing something!
Cheers Peter
