No matter what I try I cannot get a nice deep dark dark field view, all I get is gray and I have try numerous size black dots on the filter. I am using an old Leitz Wetzlar Laborlux (1950's) equipped with achromatic objectives etc. Any ideas on what the problem is? Thanks.

I know anything is possible but what are the risks of getting sick from a pond culture? Should precautions be taken, I mean other than "don't drink it?" Thanks, Joe.

AmScope PA20X-B 20X Plan Achromatic Microscope Objective Lens with Black Finish...I realize it's a pos objective but it's all I can afford right now. Will this work on my 1950's Leitz Laborlux? Thanks.

Thanks for the replies....merry christmas!

Thanks for the replies...does this mean I will have to bite the bullet and pay the high dollar price on these old Leitz Objectives?

Other than parfocal issues would I likely experience any other problems if a put a AmScope PA20X-INF 20X Infinity Plan Microscope Objective on my 1950's Leitz Scope...(it does take 170mm normally) ... Thanks, Joe.

Thanks for the replies, I have to admit it was overwhelming however .. much of this stuff is waaaaay too advanced for me ... not being ungrateful mind you, thanks and merry christmas!

Hello, I live in New England where the ponds are close to icing over now so the water is obviously very cold now. My question is if I collect some "bottom muck" right now will I still be able to get a good culture started in my jar? Thanks, Joe.

I mostly want to look at pond life, what are the most practical objectives to use for this purpose? Thanks..Joe.

Correct me if I am wrong but Leitz scopes from the 50's - 60's (the old black enamel) use odd ball objectives of 170MM, which I assume means other companies from the same era objectives will not interchange and/or will result in poor imaging? Is this a reason to avoid these scopes? Thanks and Merry ...

Yes its the old black enameled one....Circa 1958 ... Thanks

Hello all, I have my eye on a Leitz Laborlux III for a very good price however there is an issue with the Ocular adjustment: The lever that lets you adjust the distance between the eye pieces is frozen solid in place. Is this the type of thing that can be repaired by a notice such as myself or is th...

Thanks for the replies

I am thinking of buying a Cycloptic M Series Scope. Mostly what I see online about them is pretty good, I have however seen a fair number of detractors. I even saw a post (on another board) from somebody claiming to have worked on Microscopes for decades that these scopes were "garbage"...he didn't ...

Thank you.

How exactly does one go about checking alignment on a stereo scope? Thanks..

Which scope would provide better images (all things equal of course ), The Kyowa or the AO Cyclops?

Hello all, how is this fella here for observing insects, etc? How about the price? Reconditioned, 175.00 shipped? Thanks....https://www.midwestbioservicecompany.co ... -stereo-3/

Got it, thanks for the replies.

So the 200.00 Amscope will have better optics than these old timers unless its a research level scope? Thanks for the reply

Under equal conditions which will give me better images; an old scope like a B&L from the 30-40's or a $200.00 new scope by Amscope? Thanks..Joe.

Thank you, I will order that book.

Hello, just wondering if this old timer would be suitable for insect viewing? Thanks... https://www.ebay.com/itm/255262229243?_trkparms=ispr%3D1&hash=item3b6ed082fb:g:lqYAAOSwLDtfPXvW&amdata=enc%3AAQAGAAACoPYe5NmHp%252B2JMhMi7yxGiTJkPrKr5t53CooMSQt2orsSg3Ye8yTWgOW7pmE1t838dmo1OSBEOirrrGQAw9WXiRr7oIx...

I am on a very low budget (200 bucks), I just want something to look at insects with... any recommendations?, Thanks.

Thank you for the replies

Thank you for the replies.

https://www.ebay.com/itm/165297316849?h ... Swsolh7ZUm How would the optics of this compare to something brand new in the same price range? I want to mainly look at insects, Thanks.

Thanks to everyone for posting to my questions....much appreciated, Joe.

Thanks for the replies. I bought an old 1936 Bausch & Lomb scope. What are the limitation on this scope as far as objectives? Thanks again.

It seems to this novice that the quality of the objectives is the biggest factor for image quality, yes? I mean for example, one can put high quality modern objective on an old scope from the 30-60's to improve image, correct? Thanks.
