No it's not big enough to actually enter the tube - but good question. Is it supposed to? I remember that the old 1.25 drawtube did actually enter the tube (but almost an inch) but didn't come to focus unless it was racked out by around an inch...

When fully racked in, the bottom of the new 2" standard drawtube is almost exactly connecting with the outer surface of the tube. I just checked and the top of the drawtube connects with the focuser very slightly before the bottom of the drawtube hits the tube - there wouldn't be more than a mm difference!

However, being a newb I don't know what this is supposed to mean. I just know that I have to get it right. I have already used the focuser with a 1.25" eyepiece and had no problem getting it into focus on Mars.

Luckily, I've got several adapter plates of different sizes to go with the focuser, so I can make it lower profile (or higher if need be). I also have an extension tube, so that I can still rack it out further if I need to make it lower profile. I just need to find out which way to go....

Sorry for being so verbose, but I'm trying to give you a clear picture....

Thanks for your pondering!
