60mm Jason refractor

Hi all,
Hope the Refractors" forum is a good place for little junky refractors as well as for all the good ones!

Regarding my 60mm alt-az "Jason":

A week ago I pulled off the objective, and carefully marked both lenses, rinsed them off with tap water and light cotton balls, and gave a final rinse in 70/30 alcohol, let dry and replaced. It did clean off the crud, and the images are still pretty decent. However, bright objects appear very-slightly "hazy-ier" than they before at higher powers. At 100x, I don't notice any difference. Previously, this little scope could do OK at 200x, and now that is where i notice the haze.

Question: did I ruin it by doing the above cleaning?
8O

2 possibilities in my mind are that i over-tightened when popping lens back in.
Also cleaned the little barlow lens, so that could be where its coming from too.
I'm wishing I had just blown off the lens with some air or something and left well enough alone.


I have enjoyed this scope, despite its small aperature, and don't want to junk it. so I'm seeking your comments and advice.

My current junk plastic focuser needs greased badly. Last night it was pretty chilly, and the thing almost wouldn't budge. The gorilla-snot grease froze up and did not help my viewing session. I suppose I should disassemble and go with some white lithium grease for improvement (right?).

If the lens is still ok, I'm leaning towards fixing up the focuser with a 1.25 one so I can get some better EPs.

I'm pretty sure I can see Titan, using averted vision. Does that sound impossible with a 60mm achromat? Guess it could be a background star, but it is appears to be in the same plane as the rings and just looks a lot like a moon.

Thanks, and happy stargazing!

Jaron, Titan is visible in my Unitron 10X40 finder. It's magnitude 8, easily visible in a small scope.
