Automatic Re-Centering
Posted: Wed Dec 04, 2019 1:53 pm
By way of background, I have a Celestron 5se . As it's not the best mount/weight combo, I'll get a fair amount of drift over 5 minutes. Adding more weight with autoguiding only makes matters worse.
So, when the driftgraph shows too much drift, I pause stacking and then use the scope controls to move the object towards the center of the driftgraph--like a video game:)). However, it's a bit tedious and imprecise. Automating this feature based on a certain drift tolerance would enable much more precise re-centering and less time staring at the screen (assuming your scope is connected to sharpcap). In my opinion, this would avoid the need for an autoguiding setup, which is just another layer of cables, software, etc. that creates friction in the imaging process.
