Hi Rod,

Good to hear you got your head around it. It can be a little daunting at your first attempt.

With any "hand made" telescope, regardless of how well it is made, there will always be "fabrication errors". Particularly, when it is made from wood. As you have noted, TPAS improves the pointing accuracy dramatically.

It is also worth mentioning if you are limited for time, you can do a short pointing run of about 5 stars, carefully selected, just use the Index Error (IE) term only and pointing accuracy will usually be improved to put everything into the FOV of a medium power eyepiece. Clearly, the larger the group of stars sampled the better the pointing accuracy attainable, but it is comforting to know that this shortcut offers a good improvement, if you don't have much time.

Cheers,
John B
