Hi Darryl,
Thank's for your reply, o'boy there's more to this astrophotography than meet's the eye (no pun intended)

. Photography has been my hobby all my life from my box browny to 35mm Pentax and now digital Fuji S7000, so I wont let this beat me!!
What's odd is I can get spot on focus when just viewing, easy, even without hartman mask's etc. So why is it sooooo difficult with a little DSI

.
With a laptop screen to see it in , should have thought it would be easy. By the way my DSI is just the bog standard DSI not the pro.
On the Meade Envisage screen there is a zoom facility that if you want zoom's in on your target, would it help do you think to zoom on to, say a close star and focus, then zoom out, would the bigger target still be in focus???
It look's as if it might be clear sky's tonight so maybe I'le give it a try, half the fun is the challenge ( I keep teling myself)

.
All the best Dave.
