Re: Focuser Modification

I've done both. No problems except to check your focuser to ensure you don't cut off a drawtube stop that prevents the drawtube from racking completely out--there might be nothing to prevent it from coming out and smacking the ground with your eyepiece in it. The other issue is how to finish the hole you cut in your optical tube assembly if you put the focuser on the inside since you will be able to see the ragged edge. If you can properly address these two issues, then go for it.
