This is going to sound odd, but the last time I did long exposures at night, I found that using the Live View was a great way to quickly get my little points of light in the distance to be as tiny (thus, in-focus) as possible with a minimum of fuss. That and stopping down to f/8 or so. -Charles -- Charles Robinson - [email protected] Minneapolis, MN http://charles.robinsontwins.org http://www.facebook.com/charles.robinson -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
