Funddatum /Collection Date:
17.09.2019: - colony showing full flight activity.
09.10.2019: Latest two females found crawling at nesting site during rain shower. Entrance holes were still visible but partially obscured, possibly by weather erosion.
25.10.2019: even though weather was sunny, and the slope of the nesting site was fully sun exposed, no bee was seen. Neither, any of the entrance holes could be identified.
21.09.2020 A sunny, warm day, but no evidence of a thriving colony, no evidence of a single bee at the nesting site! No nest entrances. A dead pine tree had shed bark onto the nesting site. But that bark was removed about a month previous to bee-hatching time. At the Schauenburg-Ivy bush two females and one male were observed on 21st Sept. 2020. One female possessed two parasitic larvae (triungulins) of the species Stenoria analis . Was the colony killed by these parasites or was it the storm-shed bark on the nests keeping the ground to moist? Or was it a nearby hornets nest....?

Jedoch flogen zu dieser Zeit keine Bienen. / Mating observed in nearby nesting-colony observed on Sept. 17. 2019. The nest opening were discovered in November 2018 but no bees were seen then.
The species is one of three sibling species with:
Colletes halophilus Verhoeff, 1944;
Colletes succinctus Linnaeus, 1758

Orion Nebula (M42), taken in Brighton, MA.
Camera settings: 70-300mm lens @ 200mm, F/5.6, 1.6 sec. per frame, 300 frames, ISO 1250. Stacked with DeepSkyStacker, a free software for stacking astrophotographs to increase the s/n ratio.
Dendrochilum filiforme 'Birthday Present'. From a distance Dendrochilum look a lot like grasses. You have to look closely at their long chained inflorescences to appreciate that they are orchids. Each individual flower is only 3-5 mm in diameter.

normal pictures of "snowing" scene don't look like what we actually see, because mainly of limited depth of field and different exposure mechanism between a camera and human eye:
human eye is a kind of fisheye lens so has tremendous depth of field. and it takes multiple shots within a 1/16-second frame and integrate them using complex algorithm. that's why we see so much snow.
using a DSLR, if the focus is on the background, there will be "grains of salt"-like snow close to the background but not the closer bigger-looking snowflakes. but if the focus is manually set to closer distance, the DoF will be extremely shallow. stopping down the aperture to extreme setting (e.g. F/22-64) doesn't work because this will lengthen the shutter speed so that free-falling snowflakes will become rain-like streaks.
so this is how I made the picture (kind of) like real snow:
1. set the camera on a tripod, pointing toward the snowy scene
2. set the lens to manual focus and turn the focus ring to about 0.5m
3. under aperture priority mode, stop down the aperture while keeping the shutter speed at 1/500s or faster until... the ISO can no longer support the exposure (i got 1/500s at F/11 and ISO 1600. the max ISO is 3200 but it is too grainy)
4. turn to manual exposure mode and enter the aperture/shutter speed/ISO as measured above. this is to make sure all frames will have the exact same exposure
5. turn on continuous shooting mode
6. lock the shutter using a cable release to take 100 pictures in a row
7. import the pictures into the computer
8. make a set of negatives corresponding to the 100 positive images using batch process
9. stack the 100 positives together using the software "Startrails" (this conveniently stacks multiple images by keeping the highest luminosities at each pixel -- good for making star trails for cameras w/o B shutter, but also good for any other multiple-exposure applications)
10. stack the 100 negatives together using the same software (note: the snow with the sky as background appears darker than the sky, so if I only stack the positives, the sky will be washed out w/o any snow.)
11. invert the stacked negative. this will contain snow on brighter background
12. normalize both stacked positive & inverted stacked negative, to make sure both have the same (or similar) levels
13. select highlight area of that inverted stacked negative, copy it, and paste it on the stacked positive
14. align, adjust levels and do noise reduction

Mice, squirrels and other animals will gnaw on antlers for their nutrients and to wear down their ever growing teeth.
A series of shots I took of a jumping spider feasting on a fly on the garage iron post while we
were preparing an old car for some DIY body painting. I rotated this horizontally for better viewing.
He didn't mind my presence but as soon as he was finished, he took off in a hurry.

Photography information: All of the images in this database were captured with the Macropod.
The Macropod is a rigid, portable photomacrography system, which allows the user to make razor sharp, fully focused photographs of small sized specimens at 18 to 26-megapixel resolution. It overcomes the extreme Depth of Field (DOF) limitations inherent in optics designed to image smaller specimens. Normally, lenses designed for macro will only render a very small fraction of the depth of targeted specimen in sharp focus at any one exposure. The Macropod allows the user to select and make multiple exposures in precise increments along the Z-axis (depth) such that each exposure’s area of sharp focus overlaps with the previous and next exposure. These source images are then transferred to a computer and merged by an image-stacking program. Zerene Stacker is used to find and stitch together only the focused pixels from each exposure into one image. The Macropod integrates industry-leading components in a novel and elegant way to achieve these results.

This flying ants is already dead when I found it, so I decided to take several photos and stack it in photoshop...so this is the result of 12 photos stacking...macro shot using Nikon D90 + extension tube + Micro-NIKKOR 55mm lens ( reverse lens )...
Small Moth (wingspan approx 4 cm). 60 photos stacked with a step-size 20um. The photos long side is approx 3mm in size.
C/2011 L4 is getting dimmer but easier to find as it approaches the Andromeda Galaxy (M31). Photographed at 8:18-27 pm on April 2 in Cambridge, MA, USA. Stacked from 109 frames of 3.2" exposure each at 190mm, F/5, ISO 1600 using DeepSkyStacker's comet mode. The color bandings in the background came from low clouds and my attempts to manually correct lens vignetting as I did not shoot flat flames for this.
I can't repeat what my roommate said when he saw this. Especially when I told him I caught it in his room. :)
