Did something really STOOPID!

[Darkplague]

Hi,


So I bought a used 22mm Televue Panoptic the other day, and today I get home from work to the package sitting on my dinner table. I tear open the box with anticipation, and sure enough there she was.

A quick check of the lenses showed no signs of any real scratches or marks.
But they were covered in fingerprints so I decided to clean them up with windowcleaner. Anyway the bottom lens needed some attention too, so I proceeded to unscrew the chrome barrel to get to the inside lens better.

Between getting distracted by my wife and dog, I somehow managed to tip the barrel upside down and out came all the lenses and spacers onto my table.

There were: 4 lenses and 4 spacers.

The 2 outside lenses are a no-brainer,
But I'm unsure of the correct configuration of the middle 2 lenses.

Does anyone have any experience in putting the lenses back in the correct order? Any websites showing the optical array as a diagram? I looked for about an hour and couldnt find one diagram on the net.

I am currently without a scope to even test it on, as my 12" scope is a few days away still :)

Any help is greatly appreciated on reasssembling the lenses.

If no-one knows in here maybe you could email TeleVue and ask them to email you the re-assembly diagram.

[Darkplague]

Tried to find Televue's email, but no such luck. They only give out their telephone no. in America. :(

Real sorry to hear of your problem... I would suggest contacting a local Televue dealer - they must be able to get that sort of information for you.

Even if they only have a phone number, ring them! You can do it off-peak local time and it'll probably only cost a few dollars. Considering the value of the EP, it will be money well spent!! It's always easier to get an answer on the phone than via e-mail.
Good luck!

Try asking Bintel - they're the only Televue supplier in Australia. I'm sure they'll help you out.

[Striker]

Yeah ring Bintel as Mike said.....mention my name and they will look after you...wait a minute...dont mention my name...you will better off.

I'll give you $75 for it.

Don't panic Dark! you could put It back together your self trial&error before you have to send It to Televue! It won't change anything now and you will get It right after a few goes.

bintel... like mike said :)
they stock them and I am sure they know how they go together too :)

[asimov]

Is a teleview panoptic a nagler? I have plenty of EP diagrams.....If it happens to be a type 1 nagler, I have a diagram.

[atalas]

Nope !

Louie

[asimov]

What design is it then?

[xstream]

John, this link might help you?

[Darkplague]

Its a 22mm panoptic. Any diagram would help me out atm. I would say the nagler would be similar in design so it would give me a good idea anyhow!

Do you have any links? :P

[Darkplague]

I rang Bintel today and they said they would ask Televue if they could get a copy of thow the lens array is situated.

But they told me that Televue don't really like doing that sort of thing so who knows???

[atalas]

Yes thats right Dark, they will want you to ship It to them.

Louie

[Darkplague]

I know how the 2 outside lenses are situated,

All I need to know is how the 2 inner lenses are faced.
If Televue won't even tell me that then I doubt I will buy another one of their products again.

Thats a good find John !

Louie

[asimov]

Yep. Had that for awhile now....I got all-sorts of "useless" info like that, never know when it's going to come in handy!

Hi everyone

I think it's human nature to do stupid things, here's mine. On friday I decided that I should make a plaster mould to make a lap tool. I used my nicely ground mirror (I was half way through the 9 micron stage). I put a little bit of cooking oil on the mirror and proceede to pour in the plaster. The plaster stuck onto the mirror and I couldn't remove it. I should have known this as this exact same thing happened when I made my grinding tool. I started to remove the plaster and no go. I left the mirror and the plaster in water overnight. The next day I removed it.It came off quite easy (with a little tap on the side). To my horror I discovered that I had two new scratches on it. I have had to go back 3 grits to remove them(320 grit). I tried going back one grit at a time but it was all in vain. While I was doing this I ran out of some grits and now I have to wait one week to get some more. So one moment of stupidity has cost me one and a half weeks grinding. Live and learn Ha. So those contemplating grinding their own mirrors these are some of the trial and tribulations you may go through. still all good fun.

Regards Cristian:bashcomp:

[asimov]

I dunno.....not really my idea of 'fun' Cristian! But yeah, I can relate. Had to go back 2 grades of grit once or twice myself.

[asimov]

Well?? How'd you go getting that EP back together?

[Darkplague]

Well I havn't recieved any feedbackback from Televue so I went ahead and
put it together anyhow.

It really wasnt as hard as I thought it would be.

Had a look at Rigel Kent through the EP and it was clear as a bell! Looks as though I put it back in the right order.

In the end though, I had to get an airblower to blow the small particles off the lenses after cleaning. They kept on showing up in the view :(

[asimov]

I know that scenerio well....years ago I pulled apart some .965" ortho's. Still dust in between the lens, even after pulling them apart AGAIN......still dust! Oh well. Glad you can see something with it though.
