Hi Dennis,
Thank's for reply, glad we don't earthquakes around here

. Thank's also for info on DSI colour i'l put it in practice next time out. Had hoped to get out tonight to see moon eclipse but forcast is not too good, cloudy

!!
I made just as a temp. out of cardboard a star diagonal mask, on first test it seem's clearer than my 2 hole hartman and it didnt cost a penny!!
Could i just ask you one thing about the star you select for drift as i'm not sure iv'e got the right one.
In your post you say " 5 dg. of Meridian as close to eastern horizon as pos. As i live only 50 miles from maridian line to the east would my star then be almost due south
Thanks Dave.
