I tested the Roscoby in low light. It works decent. I tested it on Oct 8th from about 6:35 pm to 7:15 PM which was sunset in Western PA. From 6:35 P I had a decent picture and it did get increasingly grainy as it got darker but I had viewable video up untill about 10 minutes before dark. I have the video but I'm not sure how to post it so you all can see it. As far as the shakiness goes, it is all on the shooter as to how well he or she can remain a statue during the release. In the video of me practicing with it you can see I get better with each shot at holding it still. It is something that you have to practice with recording some shots and then look at the video to figure out what you need to do to get the shot. I also recorded a little 4 point in normal morning light in the shade before the sun actually broke out above the trees to provide bright sunlight. The camera is set up to see where your site is aiming so basically you have to keep your site on what you want to see. I'm posting a snapshot from the video of my 3 shot group at 6:45 PM. This is at 20 yds. The camera is pretty easy to use. the Pwr button has a three second delay but once the camera is on and in standby mode, pressing record starts the recording instantly. The indicator lights are bright and on the top so they could be an issue in low light as far as the deer seeing them goes but a little tape covering them some works out. It will stay on in standby mode just about all morning with the recommended batteries.
