Re: Problem achieving focus on my 100X objective

Well I followed Hobbyst46's advice and it does seem to focus properly. I guess it's finicky but ok. Oil was needed on top and it might have been a bit better with the condenser oiled as well. Thanks to all!

Problem achieving focus on my 100X objective

Hi all, after reading Roldforf's recent post on 60X objectives, I decided to ask about an issue I'm having with my "new to me" Reichert Microstar 410. I can't seem to achieve focus on my 100x CAT 1759 1.25 NA objective (using prepared Amscope sides). Seems like I can't get close enough to the sample...

Re: Microscope Cameras?

As Scarodactyl said, this type of adapter works pretty well for me. Smaller FOV than 10x eyepiece, but easy to use and good results in my opinion. https://www.amazon.com/OMAX-Microscope-Adapter-Canon-D-SLR/dp/B01D914LT2/ref=sr_1_fkmr0_2?keywords=amscope+CA-CAN-SLR&qid=1559610805&s=gateway&sr=8-2-fkm...

Thanks PeteM for your comments. I have been the recipient of significant input/advice from Apochronaut over the past few months.

more beach sand

Inspired by Hobbyist46's recent post, i put my beach sand on my AO110 with polarized light and stacked some images. The garnets are really nice. Used 40x and 20x objectives. Last image is the sand under the stereoscope. Pink grains are garnet.

Re: Shell picking from Red Sea sand

Very nice post and pics, thanks! I've been looking at local beach sand under the stereo scope too. I need to keep experimenting. Here is a sample.

The clear is quartz, pink is garnet (some with inclusions), black are iron/metal oxides. Brown looks like root beer soda bottle:)

porgy roe

Hi all.

Image stacks using my SZ7. At least two different spherical structures are evident. Does anyone know what the big translucent ones are vs the smaller opaque ones?

Porgy season opened this week on Long Island and I had some luck.

Other than the stray fibers, interesting tree-ring like structure, under polarized light.

Re: more crystals

Thanks jimur; yes, I like these too! My challenge has been with ascorbic acid where i've seen others with amazing results. I am working with pure crystal vitamin C, water and alcohol and i generally go for slow evaporation. I'll keep trying! Any other suggestions welcome.

Stitched images.

I haven't had much luck with ascorbic acid. The crystals are small and semi- opaque/muddy looking. Any suggestions from the experts? Thanks!

No, but I'm using HeliconFocus on a 1 month free trial on my mac and it works very well for me. I will purchase it when the period ends. Good luck.

Added a B&L SZ7 to my collection

Picked up a like new B&L R stand and then a beautiful SZ7. Really impressed with the view and quality. Joined my AO Cycloptic and 110. Pretty good initial results with focus stacking, cheers!
