G"Day All,
I have been noticing over the last few month that the focuser was getting hard to move in and out ,I have put grease on rake and pinion loosen the screws which help a little .I have now work out it is the draw tube which is tight . Can I use some type of oil on the tube to make it slide better .
I was think of using a silicon base spray ,or is their something better out their .
