Guiding Problem

[Tandum]

I've been checking out some of the goodies I've bought while the dollar has been high and the sky is sort of clear and I've noticed what looks like a periodic error showing up in PHD. I've never seen this before until last night and I thought it may have been balance so I spent extra time tonight to ensure my balance was right. I recently greesed the mount and spent many hours adusting the worm gears. Do you think I've got it wrong? Where should I be looking to resolve this, it's destroying long exposures.

my guess is there's a tight spot on the RA. May have to loosen up the meshing a bit more. Hope you find the problem.

I was trying to put that out of my mind, it's a bugger to get right.
I'll get the alen keys out shortly I guess :sadeyes:

Didn't see this with the 10" newt on top :shrug:

Possibly a worm issue, looks like it's happening every 8minutes during each worm cycle run?

[Tandum]

No good for 10minute subs and some are quite big ...

[leinad]

Yikes, Not sure if a pempro run will tell you where its occuring, might be worth checking out.

Got the allen keys ready, just waiting for this last sub to finish and I'll have a go at it. Just shooting the horse looking for reflections but it's diving into the city lights now anyway ..

It seems a 1/4 turn more mesh made it usable but there's still something periodic there, just a lot less of it :)

Thanks guys.
