Im using Canon Utils to fire off a sequence of shots with my 450D and Ed80. Currrently I normally fire off a sequence of 10 x 1 min .... I usually leave 10 - 15 secs between each shot.
Is this enough? Does it matter? Is there an optimal amount of time?
Currently waiting on my QHY5 to arrive so I can begin longer exposures so when guiding and taking longer subs does this time become longer?
I have a 20D modded by Eric Styles. I always leave 30 sec between shots for download and for the "chip" to cool before another shot. Don't know if its absolutely necessary but it works for me and I havn't changed it.
