Very detailed, nice shot !

Never came across one yet.

I didn't know that, thanks for the clarification Hobbyst ! I have one question. When looking through the x40 objective, the subject seems blurry, at any focus point given. As I received my isopropanol and the dust blower, I could clean my eyepieces, objectives and condenser correctly. However, the b...

Thanks ! I didn't know Zeiss condensers' filters were standardized.

I just received Isopropanol solution and a dust blower, gonna clean everything for the first time

Update with pictures of the said-slots: One with a lens: https://image.noelshack.com/fichiers/2019/11/5/1552653387-capture-d-ecran-2019-03-15-a-13-35-18.png The other one, above this one, without a lens: https://image.noelshack.com/fichiers/2019/11/5/1552653391-capture-d-ecran-2019-03-15-a-13-35-37....

Hi everyone, On my Zeiss condenser (46 52 70), I noticed there were 3 big lenses, which I think are slots for rings, such as D-stop etc. Ideally, I'd like to purchase some filters to see the differences between them. https://image.noelshack.com/fichiers/2019/11/4/1552597266-capture-d-ecran-2019-03-1...

Thanks Bill and John, I'm glad you like it.

Impressive ! What are you main subjects on this inverted microscope ?

Thanks both.

In this video, Maintenance is showed: https://www.youtube.com/watch?v=jM2lVHa ... x=4&t=337s

It looks about right for me. Yet, he didn't show the cleaning of the objectives. Is it the same process ?

Thanks for the tips Hobbyst. Is there anything to add in order to clean my microscope's objectives & oculars ?

Hi everyone, Is this item good enough to clean my objectives and oculars ? https://www.amazon.fr/Alcool-Isopropylique-disopropanol-liquide-nettoyeur/dp/B07DXD9DCM/ref=sr_1_6?ie=UTF8&qid=1550271562&sr=8-6&keywords=isopropanol https://image.noelshack.com/fichiers/2019/07/6/1550271792-capture-d-ecran-2...

Thank you a lot Einman

Thanks, I'll do that then !

Thanks 75RR for the links ! I actually tried to make one 2 days ago from cardboard, it was a complete mess Do you have a picture of a genuine one ?

Indeed, it looks like Licmophora sp. After some research, it could be Licmophora flabellata.

Thank you 75RR. What are the numbers "100/100, "80/20" ?

Fun fact: I actually saw this trinocular head, but couldn't buy it (I mentioned why in a previous thread if you remember). I am very sad aha !

Hi everyone,

Soon, I'd like to change my binocular head from my Zeiss Standard 14, to a trinocular one. There are a bunch on eBay. How do you know some kinds are suitable for my microscope, and some others aren't ?

Hi everyone, I came across this beautiful organization of diatoms attached to Ulva lactuca (green Mediterranean algae). https://image.noelshack.com/fichiers/2019/05/6/1549129719-diatome-fs20-x160-convertimage.jpg x16 Neofluar, zoomed-in while the picture was taken. What is the Gender & specie of the...

Thanks 75RR ! I just come back from the shore. So far, I'm able to see much more diatoms. The main algae I wanted to pick up is Ulva lactuca. I also came across some Cystoseira sp. (compressa ?). (Jar: https://image.noelshack.com/fichiers/20 ... 184023.jpg).

Great picture 75RR, Diatoms are lovely subjects, especially with a mastered DIC technique. How do you collect your samples ? Most of the time, your pictures are taken from sea's samples, I'm curious about your procedure.

Thank you Bill, interesting topic !

Thanks both of you !

Hi guys,

How do you clean your slides/cover glasses ? With water ?

Did you order a Phase telescope yet? I won't be able to order anything before the end of February. During this time, I'll check for a few things on Ebay/other websites: - Zeiss trinocular head - Zeiss oculars - Phase telescope - Zeiss Lens Cleaning, Isopropanol - Zeiss Phase Contrast x60 dry object...

Thank you 75RR ! I think I achieved Phase contrast on both x16 and the x40 objectives: x16 obj: https://image.noelshack.com/fichiers/2019/03/5/1547844024-img-20190118-212629.jpg x40 obj: https://image.noelshack.com/fichiers/2019/03/5/1547844034-img-20190118-213105.jpg There is a bright halo on every...

Thank you 75RR ! I took some green marine algae samples today. Here are some photos. obj x16 - Sample 1 - Focus stacking of 20 images. https://image.noelshack.com/fichiers/2019/03/5/1547838674-algue-verte-marine-fs20-x160-convertimage.jpg obj x40 - Sample 2 - Focus stacking of 20 images. https://ima...

Oh my, guys. I had a good laugh :lol: . Indeed, there were patches of bright light in the background. But do you know why ? Well, here's why: https://image.noelshack.com/fichiers/2019/03/5/1547773130-img-20190118-013043.jpg Yeah... There were these small things from the packaging beneath the microsc...

I can't say I'm not struggling on this one... I don't know if what I see is the filament or something else. As you will see, the image is repeated quite a few times, compared to your's on the slide.

https://image.noelshack.com/fichiers/20 ... 211326.jpg

Thanks for the quick reply 75RR ! Indeed, there are patches of bright light in the background. I did not try yet to focus the filament, because I wanted to show you how it was before trying it. Here were the steps: 1) Remove any opaque filters that may be in the light path. 2) Close the condenser ir...

Could you post a photo of a larger subject (an alga for example) with the field diaphragm in view (just visible along the edge of the field of view) and sharply focused. x6,3 obj: Field diaphragm sharply focused (50% of the field of view): https://image.noelshack.com/fichiers/2019/03/4/1547752060-i...
