Hi,

Yes, this was in the phase where my SCP alignment had not been very good at all. There was actually a tree in the way in my backyard (my neighbour has obligingly cut it down now ), and I hadn't yet realised how badly I was doing the initial setup.

So I would do a one-star alignment, then use Utility Func -Park, then turn off the hand control. This causes the Park position to be saved as a new Home. I would then turn on again and repeat that procedure for a 2-star alignment, starting from the previous Park - Home without moving anything in between. After the 2-star alignment I would slew to Park again and turn it off then on once more, figuring that I was improving the Home position each time.

I'd emphasise here that this was while I was still struggling with it, and it might all not be really necessary if you can get a really good alignment on the SCP first up.

Now with care setting on to the SCP I can always go from a one-star to a 3-star alignment without trouble, and sometimes a 3-star alignment alone is successful.

I think the next step might be to assess the accuracy of the altitude scale for latitude setting (I have a EQ5 mount) as I have read that it can be pretty rough.

Cheers
