hey guys, well i managed to get the scope out for a few hours tonight in the light polluted skies of brisbane, i also managed to do a decent polar alignment without an illuminated eyepiece, which is next on the shopping list, (and i realise that there is trailing in my image) which i though was a decent effort, though i have noticed a fairly prominent amount of Periodic error with a 350D at prime focus. so my question is this,
how do i go about correcting this?
preferably with out going down the expensive road (for now
)
attached is a sample pic of what i'm talking about
350D prime focus through skywatcher ED80 on skywatcher HEQ5 89s, ISO400
(see what i mean about light pollution?)
