Is this ruined?
When my health went south I packed up all my toys and this week started unpacking things. Looks like I did not do a very good job protecting this one.
Any hope for it, and how would I go about making it “right”? It was nothing exceptional but gave decent views and I hate waste.
Thanks

Re: Is this ruined?
I am not seeing anything in the image that looks like fungus so likely just condensation
If it is a doublet there should not be to much holding the lens in place.
If you can get it apart you can give the lens a good bath (soak) in distilled water and a bit of dish liquid.
A gentle scrub should clean it up fairly well.
I had a lens set that was so filthy I had to let it soak for almost 4 days before everything came off and it still puts up good views now.

Re: Is this ruined?
The original manufacturer of the scope was not given, the previous owner needed/wanted the focuser and sold off the lens (if I recall correctly he said the donor scope was made in Japan but I have nothing to verify that statement).Lady Fraktor wrote: ↑Thu Dec 29, 2022 4:32 am What make is the refractor and is it a doublet?

It is a doublet. After my session last night I pulled this scope out and it looks fairly easy to get apart. I’ll give the soak a go and while I have it down go through everything.
Thanks, I’ll let everyone know how it goes in a few days.

Re: Is this ruined?
(from experience)
Since you will have it apart, now would be a good time for upgrades.
Blacken lens edges, possibly re-spray the tube inside and/ or outside...

Re: Is this ruined?
I painted the inside of the tube flat black, and used a Sharpie to blacken the lens edges. For what it is, it really works well. Gabrielle is right too with the lens order, make it easy on yourself!
In this, the crown is to the left and the flint is to the right; picture the scope to the right of the flint; the order in which they came out of the lens cell. Easy peasy!
Best of luck and let us know how it goes!
All the best,

Re: Is this ruined?
My sharpie was pretty well dried up, I’ll have to grab another next time I am out and catch the lens edges.
Good (or better), glass is telling, isn’t it? The little 72 ed II blew this one away. Makes me hesitant to pull out my venerable little ST 80. It also makes me fear for my wallet as I am now hearing a 102 ED calling softly.
Other than the ED glass being better I did get pretty decent views with the exception of mild 4-point diffraction spikes on brighter stars. I cannot remember if they were there before or not.
I will be looking into pinched lenses, reflections off anything inside the tube and my eyesight. I wear glasses but I view without them which may be the culprit?
Anyway thanks for the help, it is greatly appreciated and I’ll keep on keeping on puzzling through this one.

Re: Is this ruined?
If the spikes don't disappear, look for a pinched lens.
Currently using a 12.5" dob and a 4" apo refractor

Re: Is this ruined?
The one night I was able to get out just a short while I saw the spikes with and without eyeglasses.
I adjusted the lens’ and hope to get in a session tonight.
Last night was a beauty with very dark, clear skies but I did not get home until very late and did not have time to cool the scope for a good try. ‘Scopes been on the deck for an hour and I plan on getting out by eight. Hoping all goes well with the scope, I’m unreasonably attached to it because it was my first conversion project.
Clear sky’s to all!
