I’ve just purchased this refractor which will be ready in 2 weeks. I opted for a feather touch focuser. The objective is being shipped from Russia and testing indicates a 0.987 Strehl. My understanding however is that this is only part of the story. I’ll be predominantly imaging but I’m sure I’ll have a peep through it as well smile.gif

 

I looked at a Tec 140mm but I wasn’t keen on what appeared to be a 9 month wait. Plus this was the last example of this scope available for 6 months so I jumped.

 

To those that know about this scope, what should I expect?

 

Simon

What should you expect?

Something close to and indistinguishable from perfection.

 

If you take to where other people are then take a box of tissue, and make sure that people understand that drooling over it, or even close to it is considered justifiable homocide.

 

Last one I saw of LZOS the lens had its own interferogram test report. It was absolutely perfect. The person that got the lens/scope/report didn't know what it meant and asked if they should return it. People offered to buy it from him immediatly for the full price he had paid.

Congratulations Simon,

I think it is safe to say that you can expect to have one of the finest refractors with simply superb optics in a beautiful optical tube assembly fitted with a glorious focuser.......  Enjoy 😊 

 

It is a big scope and really benefits from being installed on a sturdy mount/tripod combination....

 

Here is mine, yours will have a different logo on the dew shield...

Getting excited. I did a lot of research but one can only read so much; I had no access to other owners to test one out so there was a leap of faith element to it. I was looking for a scope I’d keep forever. Hopefully it will live up to its reputation!

It’s going in my observatory on my 10 Micron. Fun awaits!

I’m sure you will be happy with it..... but just in case you don’t like it, feel free to ship it to Canberra, Australia, I’ll gladly use it to make another binoscope.....

Hello Simon,

 

Almost two weeks ago I also bought a APM LZOS 152 from Markus Ludes with 99,4 % Strehl. However, as I am not an imager,  I took the 3,7" APM focusser. I am eagerly awaiting the arrival of mine. I think we both are in for an amazing observing experience ! I hesitated between the APM and a TOA 150. But the lower weight, price difference and the reputation and customer service of Markus Ludes made the difference. Can't wait to set it loose on Mars and the planets !

Waiting is hard !!!

"I just purchased an APM LZOS 152mm refractor; what should I expect?"......Seriously?????

 

You spent THAT kind of money on THAT scope, and DON'T know what to expect?????

 

You're kidding us, right?  You really didn't know if this would be any different than a 152 Celestron Achro?

Congrats.  My scope buying days are slowing down, but if money and opportunity were to intersect, the TMB version of your scope would be an exception.

Now that is an observatory!!   A worthy mount for that scope!

I’ve heard please correct me if I’m wrong it’s impossible to get an 10.00 strehl Acuracy so a 9.87 most be exceptional

I have been eyeing a 6" LZOS in the recent weeks. Why? Because I have an LZOS123 f/6 objective, that I use exclusively for AP and it is really excellent. The other LZOS I have is the 130 f/9, which I use for visual only. Since I have two larger scopes I cannot justify (in any possible way - you hear that you devil on my shoulder...) another six inch

I have not looked through a 6" LZOS lens, but reading about it and considering the quality of my LZOS scopes, I think you made a very good choice and you will be pleased with its performance. Let that be AP or visually.

Would be interesting to see how it compares with your TEC 140, and your CFF 185 scopes

I can certainly do a bunch of "+1's" to some of the postings above.  Mine was an excellent visual scope and the gent in the next town over that I sold it to, really likes it for imaging too.

 

The test certificate for my sample dated 2006, showed ~1/5 wave PTV, 1/36 wave RMS and .97 Strehl.  The DPAC images below, provides subjective proof to back those numbers up and the at focus image correlates very well to the contour plot provided on the LZOS certificate.  

 

Just a wonderful scope you will have.

 

Jeff

Simon, are you crazy...?!  Thanks God you asked this question to the Forum.

What should you expect...?! What should you expect...?!?!?!

I am telling you: by all means do not -- and I mean DO NOT -- get this scope close to you: that could provoke an endless series of unpleasant consequences on your entire life (too terrible to list them all here).

Please, please, stop the shipment.

 

Instead, do ask Markus to ship it directly to me, so that I can keep it at a safe distance from you and also do the need exorcisms to lessen its harmful power.

 

No need to pay me for this : it's indeed a gracious service I am glad to offer to a fellow astronomer.
I am so glad I can be of help that I am even ready to pay shipping and insurance.

 

Keep safe, man!

My TMB/LZOS 130mm F/9.2 is of 2006 vintage. It's probably the best scope that I have ever observed with. Your 152mm F/8 will be really superb, I'm sure laugh.gif 

 

If anything the tests that come with the scopes are a touch on the pessimistic side from independent tests of the optics that I have seen.

 

Congratulations !

Someone above said "perfection".

 

If your new scope is anything like the APM/TMB 152/1200 I had in the late oughts - then 'perfection' might be an understatement.

 

Make sure you have a mount that justifies your new purchase. Here is my kit from 2009 [ed: I just noticed you have a 10Micron - you are ahead of the curve and good for you!]
