My pollen and spores
Posted: Sun Apr 24, 2016 7:54 pm
Hi,
I hope to post my pollen and spore findings and decided to keep it all in one thread for my own and your sake. What better place to keep it than here
It's spring in Norway now and the first flowers to bloom, in my region of the country are
- Tussilago farfara
- Anemone nemorosa
- Campanula rotundifolia
It's April and a lot of other flowers and plants are joining the crowd. One of those is the Thlaspi Caerulescens. It has a curious story. It is not native to us but spread from the botanical gardens in our capitol in the 1870s. Now it's all over the country. You would think that the people working a the botanical garden would think of that!
I did a water mount. but it was still hard to find a nice photo target without depth problems. So, I did a 2 layer depth stack in Zerenestacker. I think this came out pretty clean. No dark field or anything, just my Nexus 6P.
One thing I learned, this time, is that with my setup, it is difficult to get pictures without some level of uneven field illumination. I think the sensor size of the 6P is large compared to the exit pupil produced by the eyepiece. I have applied an Astro imaging flat field technique to remove the gradient.
As you can see, I also have a slight alignment problem that probably affects the sharpness of the image. I'll fix that in my processing chain next time around.
Here goes!
