Drift Alingning

[leon]

Hi All

I'm out side at the moment doing my first drift align, i'm lucky enough to know where the SCP is, so i expect my mount is nearly already there.

I have followed all the moves for drift align and as far as i can tell it must be pretty spot on as the centered star dosn't want to go anywhere, and stays put.

I have left it running for at least half hour and still it stays there, is this long enough do you think, or would i need to go longer.

When i'll be imaging i expect that the expousures wont be any longer than a couple of minutes anyhow.

Thanks Leon

Depends on what magnification your drift aligning.....30 minutes is ample but not if you have a 20mm eyepiece in the ED80....how long do you get with at 150x....10 minutes is ample.

Hi Tony

Thanks for your answer, been new at this i didn't really consider the manification of the EP it was a 25 mm one at that.

I suppose i had better try one at a bit more Mag.

But then i wouldn't have any cross hairs, or is that not so important either, if the star stays dead center of the EP's FOV

Thanks Leon

how about a barlow.....if not put a 6mm eyepiece giving you 100X and see if the star stays central for 5 - 10 minutes.

25mm is way to low in magnification it would take all night to get any drift.

Ok Tony,

I'll do that, thanks for that

How did you go with the High Mag, Leon? Any drift?
