Hi everyone, I've been thinking about how I can build a dark frame library other then spending an hour or two after taking my light's. To be honest, it's a royal pain in the b... sitting around at 3-4 in the morning waiting for the dark's to finish. I'm a morning person & hate sleeping in late, not getting out of bed until 11:00 A.M sucks. I do not have a permanent set up which means I need to break it down in the drive way every time I'm finished. I know dark's are temperature critical & it's the sensor temp. that were concerned about along with ambient, ISO & exposure time.
On those nights when it's not feasible to image (cloudy, full moon,etc) I can sleep instead & get up at 4:00 (I love my mornings), set my DSLR/telescope with laptop outside & start taking dark's. Of course, this would be done at various ambient temperatures, ISO & exposures.
The one problem I have with this method is the sensor temp. because at the start it would no be heated up to a stable temperature. So let's say I want 30 dark frames but instead take 40 & discard the first 10. Would that work?
What is the temp. range at which dark's can be used? If the ambient is 60F do I have, let say a +/- 4F range? Is this a workable plan or do I just bit the bullet & stay up until the birds sing?
The cameras/scopes I use are in my signature..............Al.
