BTW﹐問學校借過兩三次EQ3 PRO﹐但極軸總是對不好﹐不知是自身問題還是PTC 環境不夠好?
之後就到了STAR ALIGNMENT 的問題﹐覺得很麻煩﹐又要選擇指定的星較正。唉﹐這種效率我接受不了。

Your thoughts are the same as mine. I first used GOTO with ETX and then LXD75. After about 5 minutes of hard work (on star alignment), I often got 'alignment unsucessful' as the result. I found that unless the scope was very much leveled and aiming to the Polaris, alignment often failed.
Then I decided to learn starhopping, like treasure-hunting, it is a joy on its own. I get to really know the sky.
Frankly, most DSO are just fuzzy faint stuff. The journey to reach the target enhances the joy when getting the object in the eyepiece. That may be one of the reasons why many observers didn't seem to share my joy when they were looking at DSO through my 18" (or may be just they didn't express verbally) after I had set it up for them. Also, sometimes they didn't really spend time or interest in scrutinizing the object before moving on. More reading helps to know what to 'look' at the faint fuzzies.
As one of my form 2 students said before, one needs to observe with the brain.
So by the time I got HEQ5Pro (which I still use now), I almost never used the star alignment (except when doing photography, which I very seldom do), so I don't know if the technology has improved to make sucessful alignment easier especially when Polaris is not observable.
