Hopefully I am posting this in the right place.
Just a quick question. I align and then physically focus in on what I am seeing in my optical tube. I then take the eyepiece off and attached my Canon Rebel XS with the t-ring adapter to the telescope, look at the display screen and everything out of focus. Why?
It's easy to focus back in when I am looking at the moon but not so much when there is only faint stars.
The end goal here is that I am trying to do long exposures and that can't really happen when the image isn't in focus.
