When I got my pretoria eypeice sometime back the upper lens group was a little loose and it had let a little dust in, upon dissmantleing and almost dropping the field lens on the tiles I got it back together
but neglected to clean iside the eyepiece barrel.
Skip forward a couple of years and I thought ok I pull it down and clean it again,which all went well though it did take a while , so I go outside look through the eyepiece , and wow thats spotless now , but the view is completely warped , oh crap I've put something back in the wrong way round , pull it down again , flip the upper cemented group and
get it all back together, go outside the views still completely warped .
pull it down again put it back the way I had it to start with, drag out scope, set up , try to focus on tree in distance no go .
Strip again flip that upper lens back and put it back together again.
( note this is not a complicated design only one bit you can get wrong)
stop for lunch
back outside put eyepiece back in focuser , *#*!~&*# still won't work!!.. major dummy spit.. calmed down an thought a little.
have you ever really looked through the glass outdoors and noticed that warped view or otherwise before ?... well no
are those trees I'm trying to focus on to close, like I'm sure I've visited this before and had to go out front .. possibly.
Ok back inside put it all back the way I started with , waited for a clear night , works fine
