You are already ahead of me in astrophotography, I'm still working on getting autoguiding working properly

I was amazed with autoguiding. Everything in astronomy is expensive and hard except this.
I have a cheap (ebay) 70 mm saxon achro and once i worked out how to focus it with my 100 buck meade dsi i was autoguiding in a few minutes with PHD a brilliant program.
Maybe i was lucky, but strangely this was an easier thing for me. Now drift alignment, that took me ages to learn and was very confusing. I am getting better at it and doing wide field makes it a bit easier but it still takes an hour.
Anyway, try PHD if you havnt already it is @#$% fantastic.
