Back at Granite Gap

I left Ajo last week and drove to Granite Gap, just across the border in New Mexico. I planned to stay here awhile and do some astro and that has been working out OK. Otherwise, I think it is drier here than the Ajo area. There is not much vegetation that is green. There is a herd of cattle on this BLM land and I’ve been watching them eat prickly pear cactus. There is no grass for them to eat.

I’ve been adding more time to NGC 4725. I’ve lost track of the hours of exposure, but it must be around 6 or 7 by now. I think it is worth it. As always, right click on an image and open in a new tab or window for a larger image.
The larger, eliptical galaxy is M60. Eliptics by themselves are not very interesting but something else happened here. The small galaxy is NGC 4647 and what appears to be a star from our galaxy in the lower right portion is not. It is a Type 1a supernova in NGC 4647. I don’t have a before/after photo but a look at Stellarium confirms this. I read about this on Spaceweather.com and decided to try for it. Both galaxies are about 60 million light years distant in the Virgo galaxy cluster. Type 1a supernova involve a white dwarf in a binary star setting.
NGC 4753, also known as the Dust Devil Galaxy, is a lenticular galaxy in Virgo. It is known for the dust lanes that surround the nucleus. I wanted to see if I could capture those dust lanes. This is a very small galaxy and long way out there; the C8 continues to amaze me with its capabilities. The Losmandy G11 mount and the LaCerta MGen III autoguider gets a lot of credit too.
I’ve added more time to M104 too. The inner dust lanes are starting to show up.
Before I left Ajo, I went on one more night walk up Child’s Mountain Road. There, I found my 3rd Rosy Boa. It is quite fascinating to think about all the years I looked for this species and never found any and now, since last fall, I’m up to three.
There was also a Sonoran Lyre Snake. This is the only location I’ve found this species.

My First Quasar, Even Before the First Quasar

Last month, I posted about the first quasar that I had ever knowingly photographed. My story was that while waiting for the galaxy NCG 4151 to rise high enough to capture two quasars, I spent a couple of hours photographing M97, the Owl Nebula. Well, today I was reading some posts on Cloudy Nights forums and found that there is an easy quasar by M97. I went back to my photos and sure enough, there it was. I have probably photographed lots of quasars and didn’t even know it. Now I have three different identified quasars.

And there it is, 8.5 billion light years, I am photographing light that left the quasar before our solar system even existed.

More Nectar Bats

I had to go try again. There is something addicting about this, to keep taking photo after photo hoping for that one great photo to appear. It doesn’t happen very often. I can’t say that any of the images I got last night are great, but there were some keepers. As always, one can right click on an image and open in a new tab or window for a larger view.

My hosts have a tall step ladder to get closer to the agave flowers. Last night I used some bungie straps to fasten my tripod to the ladder and got this. I think I should have spent more time on the ladder.
I spent most of the night working the bats at the Octopus Agaves with a handheld camera/lens, prefocused. Here is a Lesser Long-nosed Bat taking off after getting a drink of nectar.
There is a species of bat called the Yellow Bat, but this isn’t it. A Lesser Long-nosed Bat covered in pollen.
It seems like there is room for all at these agaves but the bats have their conflicts.
Ow!
A bundle of bats.

Another Rosy Boa

A couple of nights ago I went back to Valentine Well to try for, once again, a good shot of a Townsend’s Big-eared Bat. I got no photos of that species. Bat activity at the well was pretty slow. All I got was more Yuma Myotis photos. I stayed until about 9 PM then headed back to Ajo on the Scenic Loop Road and Alley Road. As always, I was looking for snakes or whatever else might show and was pleasantly surprised with a Rosy Boa, only the second one I’ve ever seen.

The only keeper bat photo of the night was this Yuma Myotis.
Here the boa has rolled its underside up and one can see the black speckled markings there.

Nectar Bats in Ajo

Paul and Linda, fellow snowbirds and friends of mine in Ajo, own a home that has a remarkable variety of desert plants in the yard. There are several species of agave and some of these are blooming now. Nectar bats have appeared in good numbers, I’ve spent a couple of nights there photographing them. The laser trigger won’t work in this setup, so I just prefocus on a point and hope a bat comes to it.

All of the nectar bats appear to be one species, the Lesser Long-nosed Bat. This one had just finished feeding and is dropping off the flower.
While feeding on nectar, they get a lot of pollen on their fur. This species is an important pollinator of desert cacti and other plants.
This image isn’t very sharp but one can see the yellow pollen on the bat.
I find it very difficult to get a good angle on the bats and I don’t get many sharp ones, so I can’t be too picky about which photos to keep. I shot over 200 images and only a dozen or so are worth keeping.
Another bat leaving the flower, they don’t stay on the flowers very long.
I think this is my favorite one so far. As always, right click on the image and open in a new tab or window for a larger view.

A Supernova and Other Things

The weather continues to be nice. Birding hasn’t been too exciting except for a pair of Forster’s Terns that appeared on the ponds one day. These are the first terns of any species I’ve ever seen on the Ajo sewage ponds. Astrophotography has been hit and miss with clouds and wind.

This is NGC 3367, a galaxy that is so small in view that I wouldn’t typically bother with it. It is way out there, 120 million light years away. What makes it interesting to me now is the Type II supernova that occurred recently. Well, I should rephrase that, it occurred a long time ago and we are just seeing it now.
And there it is. I captured a supernova in the Fireworks Galaxy some years back but wanted to try this one too. This is the sixth supernova reported from NGC 3367 in the last 30 years.
One of the two Forster’s Terns at the ponds. First terns I’ve ever seen here.
Yesterday I was at Highway Tank and was pleased to find this male Belted Kingfisher. There are no fish in the tank but it was catching large aquatic insects, some looked like dragonfly nymphs.

Birds, Bats and Galaxies

It is that time of year again, where there is so much to do I can’t decide what to do next. One result is I don’t get much sleep. I finally caught up on sleep last night.

A couple of nights ago, I captured about 2 hours of the Sombrero Galaxy, M104, and added it to what I captured last winter. I’d like to get even more, weather permitting.
Same with M106, I added more to what I captured last winter. It is starting to look very nice. Even though these galaxies are tens of millions of light years out there, it is a sissy skip in distance compared to the quasars I posted earlier. Hardly even worth mentioning anymore.
And M65, one of the Leo Triplets, more data added to what I had from last winter. The frustrating thing about astrophotography is the amount of time it takes to get a good image. At least the nighttime temperatures aren’t as cold now and it makes it more enjoyable to be outside.
Last night I went to Valentine Well again and got this shot of a Pallid Bat in the act of getting a drink.
A female Gila Woodpecker showing its underside. There were four of them having some kind of dispute and they all liked to hang on the fence while doing it.

The Twin Quasar

I mentioned in my other post about quasars that there was another project I wanted to work on. This is it. This is one of those images I did just to see if I could do it. The Twin Quasar was discovered in 1979 and is the first gravitationally lensed object identified, thus proving Albert Einstein’s prediction from his General Theory of Relativity. Einstein thought that humans would never be able to actually observe this effect, but it has now been observed numerous times.

The larger galaxy is NGC 3079, also known as the Phantom Frisbee Galaxy. It is located in Ursa Major about 50 million light years from Earth. However, that is nothing compared to the Twin Quasar, which is 8.7 billion light years out there. This is by far the farthest object I have knowingly imaged. The age of the solar system and our planet is around 4.5 billion years; the light that is captured from the Twin Quasar left before our planet even existed.
What looks like two stars is actually a quasar with a galaxy between it and our planet. The galaxy (designated YGKOW G1 and too dim to see in this image) is about 3.7 billion light years and the quasar is 8.7 billion light years. The effect is known as gravitational lensing, the warping of space-time as it passes massive objects.

Read more about gravitational lensing and at this link there is a Hubble Space Telescope image in which the galaxy causing the lensing can be seen.

An Evening at Valentine Well

Friday afternoon I drove back out to Valentine Well. The weather wasn’t as warm as I had hoped but I still thought I could get some decent bat activity. About a mile before the well, I saw a sight that one does not often see here in the heart of the Sonoran Desert, an Osprey.

A rare sight around the Ajo area, an Osprey, and even rarer to see one perched on a Saguaro. I think I’ve seen Osprey maybe twice before. There is no water with fish for at least 60 miles, but the birds are common along the Sea of Cortez and of course will migrate through. But landing on a Saguaro?
The main reason I keep trying for bats at Valentine Well is to get a really good photo of this species, Townsend’s Big-eared Bat. It is always close but so far I have none that are really sharp and contain the entire bat. This one is not sharp but otherwise it would be perfect! My big hope is for a Spotted Bat to start using the tank.
Yuma Myotis are the most common bat out there and most of my shots are of this species. Therefore, I get more good ones. What I need is good photos of different species.
This Yuma Myotis is coming in for a drink.
They are very fast, and they don’t slow down much for a drink. As always, right click on an image and open in new window for a larger image.

Birding Report

Bird migration is picking up nicely. I’m seeing first of spring Bell’s Vireo, Warbling Vireo, Lucy’s Warbler, Wilson’s Warbler, Bullock’s Oriole, and many more. I went out to Valentine Well a couple of nights ago to try some bat photography. That didn’t work out but I did see a Poorwill. Nights are warming up, no longer do I need four blankets! The lack of rain results in very few wildflowers, unfortunately. It is very dry.

I’ve been hearing about a Lewis’s Woodpecker around town, it has apparently been here all winter. I finally caught up to it.
There are lots of Lawrence’s Goldfinches moving through the area. Some days I can see over 30 at the golf course. Here is a flock watering with a Gila Woodpecker.
These Lawrence’s Goldfinches were bathing at a pretty close range.
