Drift alignment re: Spica(?)

[northcanadian]

Hi folks:

I'm just wondering if Spica tonight would be good for tweaking my drift alignment?  If it is a bit high will it matter?

Thanks again!

Cheers

Hi Roger.

My prefered way of drifting is by using the DARV method and last night I backed this up by using the PHD method.

I think the PHD method is blindily easy and adjustments are realtime.

As to your question, I stick to stars that I can see easily, any star near the meridian and equator.

Any star to east and close to equator, normally this star would be 20degrees above the horizon.

My obsy at the moment does'nt allow me to see the meridian, so I come round to the SE a bit and

I cannot see stars below 20degrees altitude.

Don't know about stars that are high and what the results would be.

Thank you for your reply.

I did try it on Spica last night (just before the inevitable clouds rolled in)  and It did help....Saturn hovered pretty well in the center of the reticle eyepiece with just a slight bit of drift. Hopefully tonight can also use Spica to tweak collimation.

Cheers
