Meteorite Hangout

[@jeffdevries2269]

Fantastic job as always Topher!!! High quality material by all!! Thoroughly enjoyed this episode :)

[@TopherspinMeteorites]

Thanks Jeff 😁 It it always a pleasure to spend time with the Crew and you. Thanks for the IMCA letter too.

[@gametimegallery7661]

Excellent knowledge sharing session. Thank you for posting this, and your other videos. A few years ago there was nothing on the Internet on how to care for iron and stony-iron meteorites. Your videos have been an incredible help.

[@TopherspinMeteorites]

Thanks so much for taking the time to write this great comment. One of the reasons I started doing this was a lack of meteorite educators online. No, 'Meteorite Men' did not fill that void. 💚

[@ianmiller5027]

Once again a very enjoyable and informative hangout Topher. Congratulations to you and the crew members

[@TopherspinMeteorites]

Glad you enjoyed it even without any real show & tell of meteorites. Thanks Ian!

[@allocke8054]

Really good information tips & advice guys I'll definitely be looking into the cross polarisation now i understand it better & finding Sue's metbull updates really interesting & useful

[@TopherspinMeteorites]

Awesome 👍 Thanks for letting us know. Sue is so happy.

[@bettyjane978]

Aawww, thanks Al!! I am actually learning so much whenever I research the Metbull each month! If you told me four years ago that I would be doing a monthly segment about meteorites during Topher’s hangouts, I never would have believed it! Ha ha…. I have gone full nerd!! 🤣

[@allocke8054]

@@bettyjane978 very true meteorites are addictive & you're doing a great job with your part 👍

[@AstrogeoJay]

That was quite a dramatic contrast with the cross polarisation, I kind of thought I had a basic understanding of it, but when you see it like that its an eye opener! I have a decent DSLR similar to the one Domyan uses and a specialised macro lens , well I have 2 macro lenses but one is for really close stuff I think only Canon makes such a lens (called a MP-E 65mm f/2.8 1-5x Macro Lens) but they are quite pricey, even though mine was second hand it was still not cheap, certainly compared to some of the stuff Domyan uses which probably gives better results! but my light set up needs to be improved and after seeing this it is obvious I need to get some of that linear polarising filter. Thanks for hosting the meteorite hangout and for all the people who take part.

You can use CPL filters, especially if you want to keep using some of the automatic features MP-E may provide. I use two CPL filters on my main setup and a LP on my LED light. The trick is to always face the front of the CPL filter towards the subject. The 'back' side simply has a 1/4 waveplate so you face that side toward the light source and toward the camera sensor. If you already have two CPL filters there is no reason not to experiment with those. MP-E is a legendary lens but it's extremely overpriced. Most features you get are not needed. You are better off not using any of the automatic controls and the higher light gathering power compared to microscope objectives can easily be compensated by slightly bumping the power of your flash (I am still using it nowhere near full power).

[@TopherspinMeteorites]

This reaction is why we did the demonstration. Never underestimate the results of 2 thin films of plastic. 🏆 It was very nice to see you and Domyan chatting about photography details.

[@dsvilko]

It's absolutely true that for a more serious macro photography you are shooting in manual. And I mean full manual. Auto focus is useless - no lens can do auto focusing at those magnifications and you want full control and predictability for stacking. In macro photography you focus by moving the camera or the subject, not by turning any kind of a focusing ring. As you almost never have aperture control and as you HAVE TO use the flash (any exposure longer than 1/200s would produce motion blur from a shutter shake and no continuous light is powerful enough for such a short exposure), the only controls you have left are ISO (and you keep at at 100) and power level of your (also manual) flash. Even the white balance you want to keep on a fixed custom (calibrated) setting. You can't allow your camera to change anything between possibly hundreds of exposures needed for stacking.

[@TopherspinMeteorites]

Thanks so very much for making the video on macro photography and also for adding this extra information that you weren't able to fit into the video based on our discussion.

[@dirkjackson1267]

So very cool 😎 enjoyed much!

[@TopherspinMeteorites]

Glad you enjoyed it. I think it is packed with usable information.

[@jamesgraves6216]

Excellent demonstration Pat.

[@TopherspinMeteorites]

He worked hard to keep it short 😎 and hit a home run. Thanks.

[@mohamad3abdolah2]

A great set of professionally photographed meteor cameras

[@TopherspinMeteorites]

Yes, thank you for watching. I hope you are able to join us in learning.

[@kpixelz]

Great crew and best MetBull Update ever!

[@TopherspinMeteorites]

Thanks so much. That made Sue happy.

[@bettyjane978]

Thank you kindly!! Comments like this make my day!! 😊

[@TenesseeTuxedo1]

You blinded us with science! Great instalment

[@TopherspinMeteorites]

Yessir! That's the goal. I will be your Thomas Dolby and your Huckleberry!

[@conancarroll4780]

Nice hangout!.. Mike's advice on disc's vs sandpaper is the 💥..surely it works on earth rocks as well...thank you!

[@TopherspinMeteorites]

He is full of great tips! I learn a lot from all my friends. Pat already started using discs after last week. Thanks!

Topher thankyou for being you my friend. this is gonna sound weird but mad love bro!!

[@TopherspinMeteorites]

No worries - I like weird. Thanks for the great feedback and for watching.

[@freshimpactco.8698]

Ok so Pat this is a comment for you, you have no idea how long I have been waiting for your amazing knowledge on cross polarization of light. Pat can I ask if this is this something you studied and experimented with? Would you be willing to create both setups and sell them? I would be very willing to send you a free meteorite as a thank you as well. I would appreciate it very much, maybe I can buy it through your website Topher, I am also after 2 rare earth magnets. Pat is really ingenious.... Thanks to all of you for another amazing session, don't know about you guys but you deserve 30,000+ subscribers on your channel...

[@TopherspinMeteorites]

I passed this along to Pat. Thanks a bunch. 30k subscribers would blow my mind. The Crew is helping me get ready for this week's Hangout. It will be epic.

[@DR_SOLO]

@ 30:00 that should have screw threads. on it. to attach to a clip so you can clip on to your mobile device. 🤠👍🏼

[@TopherspinMeteorites]

Not for this handheld pocket size little tool to bring with you mobile. There are others that are designed to attach to your phone with a clip.

not for nothing I will never ask you again, with that being said. I found a shoebox size Rock / Stone, Strange to me that it word weigh 29.5 lbs . in this particular specific video you are holding a stone/ Rock in the thumbnail, that to my eyes and mind seems very similar to the one that I uploaded a video of here on KZbin asking for any insight on to what it might be. If at all or if ever you have a spare moment could you, would you be willing to take a gander at it and give me your expertise opinion. I don't expect much it's simply a video. I would never expect someone to observe something on the video and be able to give precise details or a exact identification. but curious to me is how similar they look. so what kind of stone / Rock is it that you're holding in the thumbnail exactly?. 🙄🧐🤔😳

[@TopherspinMeteorites]

There is no scientist or experts that would use a picture of a rock in a thumbnail taken from 20 ft away. That is not a diagnostic quality photo in any way or stretch of the imagination. I am holding the largest meteorite ever found and officially scientifically classified as a real meteorite from Massachusetts. It is named Barnstable, all of the information can be found on the MetBull. And, if you search my channel for Barnstable, you will see an interview and conversation with Stephen Amara the finder who's a personal close friend of mine. Every single video I've loaded in the past 300 have given you complete instructions and links where you can load pictures to have experts look at them. I do not look at them myself but if you load them in the group I may pop in and take a look at them.

[@DR_SOLO]

@@TopherspinMeteoritesI will go search the links and process them through those manners thank you I don't know why that slipped my mind appreciate the time you took to explain the meteorite that you're holding in the video done now cool beans.. many people will probably be disappointed when they find out that they're not holding the meteorite but for me it's the adventure it's the Wonder and sometimes not knowing is the best part.🤠

[@DR_SOLO]

because when you find out you don't have a meteorite it doesn't feel the same anymore if you know what I mean I'm sure you do
