Male Hummer (Big)

Posted By Jeff Hapeman
This is from the same set of photos as the preceding female, same gear and specs. This one I wanted to post at native resolution so you could see the details...I found them amazing. This is a crop, but not otherwise reduced. The male never seemed to turn the right way so I could get the ruby throat to show, but this will do.

One last hummer

Posted By Jeff Hapeman
This one actaully really froze the action, but it took 1/3000s to do it.

I said I would...

Take up some dragonfly photography. We just bought a vacation home in northern WI. The property has lots of bogs--which I love--in addition to the lake. There is a bog on the property that is about 25 acres in size, and I went tramping out there today and got this picture of a female Calico Pennant (Celithemis elisa) while trying to photograph some sundews. More pics from the trip to come, but this is one of the prettiest dragonflies I have ever seen. Nikon D100, 200mm ED Micro-Nikkor lens.

Sundew

Posted By Jeff Hapeman
This is another shot from the bog on my place up north. It's a Round-leaved sundew, Drosera rotundifolia. The leaves are only about 1/4" in diameter, so they are tiny. I love the little jewel-like drops of sticky stuff on the hairs, but the insects that get caught in them sure don't--this plant is carnivorous.

Nikon D100, 200mm ED-IF AF f/4 lens.

Another Dragonfly

Posted By Jeff Hapeman
This is another picture from my house in northern WI. This is a male Chalk-fronted Corporal (Ladona julia). They are known for landing on the ground a lot, and that they do. They are also easy to approach to within 6 feet. With the 200mm macro lens on the Nikon D100, I can get a good shot at that distance.

Not quite enough depth of field here, but I still liked this shot. Nikon D100 and 200mm macro lens.

Animated Milky Way

Posted By Jeff Hapeman
I was on Kitt Peak last week doing some high-resolution imaging of summer nebulae and took some time to make this little animated GIF. This is--if I recall--28 images in sequence, covering two hours and fifteen minutes. I used my Nikon D100 with the 17-35mm ED-IF AF-S II lens set at 17mm (25.5mm effective FL) and f/3.5. I took a 30-second exposure every five minutes at ISO 800 and using the long-exposure noise reduction function. The images were stretched in PS to more clearly show the structure in the Milky Way, but that enhanced noise. However, that was resolved by reducing the image size, which was necessary to keep the animated GIF relatively small.

So, without further ado, here is the summer Milky Way rising over Kitt Peak--a wonderful sight at a wonderful site.

Light Pollution example

Posted By Jeff Hapeman
Even Kitt Peak has to deal with light pollution. This is the view to the ENE towards Tucson. There is a fairly decent light dome at Kitt from Tucson, even with the legislation designed to reduce light pollution. If you look carefully, you can clearly see the fires consuming Mount Lemmon at left center, and a smaller fire in the Rincons at right center.

This is a 10s exposure with the Nikon D100, 17mm at f/2.8.

Acorn Woodpecker

Posted By Jeff Hapeman
One of a bunch of shots I will be posting over the next few weeks from my trip last week to southern AZ. This was taken at Kitt Peak. This guy flew in and chased off a Mexican Jay I was trying to photograph, but I didn't mind too much.

Nikon D100 with 80-400mm VR.

Violet-crowned Hummingbird

Posted By Jeff Hapeman
An extreme southern AZ specialty. These guys are big, fast, and never landed anywhere but the feeder. Did I mention that they are also spooky, and with as many as 50 other hummers around, they never sat for long. I waited about 30 minutes to get one series of shots from about 8 feet away. The blue head does not show strongly here; it required the perfect angle for optimal refraction. The only shot I had that showed it was poor otherwise in framing.

This was taken at the Paton's famous batch of feeders in Patagonia, AZ last week. Nikon D100 with SB-80DX speedlight and 80-400mm VR lens.
