Best Polar Alignment Practice

I did a 250 point T-Point model last night (F3.8 rocks, 3 second exposures at 3x3 binning was taking very little time to do each point).

I had jut finished 2 hours of quite good round stars on the Honders, PMX,Portable pier (very solid), MMOAG, STi. All very tried and proven stuff.

I did the relatively minor mount adjustments the polar alignment report said to do.

Then I started to do some more imaging and got eggy stars - what????!!!

I then switched to Pempro Polar Alignment wizard. It had me adjusting the mount big time - what!!????

I was then getting much better stars but not as good as when I started first thing - great!

So I am now wondering just how good is a T-Point model? I have had good success with it in the past.

I guess I'll do several 35 point models tonight and adjust the mount each time until the report says it good enough and see how that goes.

What do you use?

Greg
