Re: Battery life
I doubt it, most likely your battery pack is not in good shape. What kind of batteries and how big is the pack made off? I sometimes use a 5ah lead-acid gellcell and its good for two

Re: Battery life
The G11 should consume less than 1 amp per hour, but for safety's sake, estimate that rate. The DSC's consumption should be negligible but again, play it safe and estimate 0.5 amps per hour. If you

Re: Battery life
I use a 34 amp hour marine battery (a small battery, about the size used in rider mowers) for my G-11 /w DSCs and it lasts all night long even in the winter. I use marine batteries because unlike

Re: G11 Fix (III)
Hi Paul...I've got that one but what I'm trying to do is extrapolate that to the 4x6"photo print of my star trails. If I had used the st-4 or st7e I know this would be a lot easier than photo

Re: G11 Fix (III)
A simpler formula for #1 below is: Arc-secs per pixel = (pixel width / FL) * 206 You can nearly do this one in your head. Certainly with a simple calculator. It provides almost exactly the same
