Not finished yet but I had a busy week to prepare @ransonad new @INSS_UK microscope! 4 lasers, 3 @TOPTICA_AG one @CoherentCorp, 3 delay lines, 1 SLM, 2x RGG scanners. Thanks for having me and see you in the new year! #microscopie #multiphoton #neuroscience

[Lionel Tcatchoff @lioneltca]

@INSS_UK , we always like to see your sample when setting up a new microscope! That looks great!

[Bruno Pichler @brunopichler]

I had a great time with Jean-Christophe Billeter and Robin Bakema at the #GELIFES Institute at @univgroningen . It was my first time seeing an INSS 2p microscope being used to image sperm in the seminal receptacle of female drosophila. Pretty fast, the little buggers...

[Lionel Tcatchoff @lioneltca]

Looks like an exciting programme!

[EmilianiLab @EmilianiLab]

Heading to Chicago for #SfN24. As usual, I don't have a booth. Instead, I'll be roaming freely through exhibition halls, seminar rooms, and poster aisles. Please message me if you want to meet up for a coffee or beer and chat about 1-, 2-, or 3-photon microscopy.

[Sepiedeh Keshavarzi (@sepikeshavarzi.bsky.social) @SepiKeshavarzi]

Very excited about the latest addition to the lab & can't wait to see those twinkling cells! Thank you @INSS_UK for building this beauty🔬

[Lionel Tcatchoff @lioneltca]

Come and join us, it can only get better and it is already pretty awesome!

[INSS @INSS_UK]

We are looking for a multiphoton microscopy enthusiast to join our team. If you love tinkering with lasers and lenses and like Open Source DIY microscopes, please take a look at what we have to offer: https://t.co/qGnvTezphw

@brunopichler @Thorlabs @ptrrupprecht I have talked to @thorlabs today at FENS and the instinctive response was humidity problems, but the support team may have more insight

[Lionel Tcatchoff @lioneltca]

@trose_neuro @INSS_UK @ptrrupprecht @Labrigger I've seen a high turnover in very humid environment. But it looked more like tarnished/yellow, never the rim and dots as shown here...

[Lionel Tcatchoff @lioneltca]

Indeed I am there in Vienna. Do let me know if you want to have a chat! #fens2024

[INSS @INSS_UK]

Our Senior Application Scientist @lioneltca will be representing @INSS_UK at @FENSorg #FENS2024 in Vienna next week. Please get in touch if you want to meet with him and chat about 2p, 3p, mesoscopes, optogenetics, etc

@ValaAfshar Cautiously optimistic...

This may be the most important equation in business, politics and life.

[Lionel Tcatchoff @lioneltca]

Had fun installing a 2P setup for @TobiasAckels with @brunopichler using @TOPTICA_AG's FFultra 920 and 1050. System with dual color or imaging and photostimulation. Tobias's group will study spatial olfactory info processing. #microscopy #multiphoton #neuroscience #olfaction

[Fabian F. Voigt @voigtvision]

Dear #Microscopy hivemind: What's the current take on using the @Thorlabs Silicon Photomultipliers for multiphoton imaging? Has anybody played with them? Are people happy with the dark counts? @PodgorskiLab @brunopichler @Labrigger @ptrrupprecht https://t.co/EWNDLeFOrJ

[Bruno Pichler @brunopichler]

It was great fun to work on this preprint with @robmlees @ibianco3 @raacampbell @natorlova Darcy Peterka @labrigger @YatsenkoDimitri Che-Hang Yu & @paqio.
Hope this helps many people to characterise their 2p microscopes https://t.co/oGBfUNNkud

[Lionel Tcatchoff @lioneltca]

So true! Too much resources are wasted for the questionable learning experience. One learns more with a few hours of "expensive" expert consultation than several weeks/months of trying on one's own. But that has to be integrated in the funding process...

Why (and how) we need to professionalize neuroscience

[Lionel Tcatchoff @lioneltca]

That's a great start, but I'm sure @brunopichler is not limited to those topics!

[Bruno Pichler @brunopichler]

I'm also happy to discuss any other questions at #SfN2023, including the classics:
Is there a life...
... after leaving academia? 🥳
... as a microscope builder? 👨‍🔧
... as a bluegrass musician? 👨‍🌾
... after Brexit? 🤮
... after death? 🤷‍♂️
... before death? 🤯

[Lionel Tcatchoff @lioneltca]

Experts in #multiphoton 2P and 3P #microscopy wanted for #postdoc May be a #neuroscientist interested in the technical development of the technology and excited by the challenges of a different organ?

[Lionel Tcatchoff @lioneltca]

@LavivTal @brunopichler @INSS_UK @FloridaImaging @LavivTal happy to help! Let us know how it goes!

[Lionel Tcatchoff @lioneltca]

Happy mouse under @LavivTal 's new microscope! Happy clients and happy mice for 2P imaging make us happy @INSS_UK! Thanks a lot for having me the last few days and have fun!

[Bruno Pichler @brunopichler]

@Labrigger 's Cousa objective looking great on @INSS_UK microscope
