The new moon has come and gone, and I had to deal with a lot of clouds, heavy dew, and cold. However, with the new filter I was able to take advantage of some good weather over the last few days and I had great results. Birding has remained extremely slow, nothing but the regular desert birds. I had nine photos printed for the Sonoran Desert Photo Show that is taking place in March. It is always interesting to see all the photos that are on display, I hope there is good turnout.
I tried this once before with the C8 but it is so dim that details were hard to catch when imaging at f6.3. The last couple of nights I used the 500f4 and the IDAS Nebula Booster filter and the results were amazing. This is the Medusa Nebula, or Sh-2 274 or Abell 21. It is a planetary nebula, what our sun will look like sometime in the distant future as it loses its outer layers of gas and transforms into a white dwarf. The Medusa Nebula is about 4 light years in diameter and 1500 light years distant toward the constellation Gemini. Also done with the 500f4 and the new filter, the Cone Nebula, the Christmas Tree Cluster, and the Fox Fur Nebula. The faint nebula is approximately seven light-years long (with an apparent length of 10 arcminutes) and is 2,700 light-years away from Earth. Thor’s Helmet with the new filter. I also used StarXterminator to remove the stars before processing. There are so many stars they overwhelm the image if they aren’t removed. I’ve never been able to get so much detail from the dimmer areas of this nebula. This is the Seagull Nebula, a large emission nebula between the constellations Monoceros and Canis Major. I could not fit the entire nebula in the frame with the 500f4. I may have to try a mosaic someday. You may notice the prominent bluish arc in the lower center area. This is a bow shock from runaway star FN Canis Majoris.I was at Highway Tank a couple of days ago and found this Least Sandpiper. Not exactly an exciting bird to see but it was the first one I’ve ever seen at Highway Tank. This bird puts my species total for Highway Tank at 120.This is a Desert Orangetip, the Pima variety. The Desert Orangetip ranges widely from far west Texas to southern California and into Nevada. The eastern populations are yellow on the upper wing (Pima Orangetip) and western populations are white. One of the earliest spring flying butterflies, this one is nectaring on Fairy Duster.
It is hard to believe that it is already February. It is also hard to believe how much rain the Ajo area has been getting. The ground is soggy and the mountains are green. Barring an unwelcome spell of freezing temperatures, there should be another spectacular spring bloom of flowers. Already, some are showing up. Birding has been very slow but there are signs of migration, friends in town reported seeing a Rufous Hummingbird today!
I have added more time to the Dolphin Head, I’m up to about 6 hours of exposure now. Using the new duoband filter sure makes this pop out. This is Ten-mile Wash a day after the heavy rain last week (January 22-23). Some areas around Ajo got nearly 4 inches. I’ve been coming to Ajo for almost 10 winters now and have never seen the wash with flowing water. This morning it was running again, after another inch of rain last night. Ten-mile Wash is about 1/2 mile from my camper. This morning Vikki Jackson and I hiked up McGrady Wash. We saw one butterfly, this Sara Orangetip. Fortunately, it landed a few times and let me get some photos. It has been a long time since I have had any good butterfly photos to show! Some consider this to be one species within the Sara Orangetip complex, the Southwestern Orangetip. A Canyon Wren that eventually came close enough for some photos. We also found this flowering plant, Pseudorontium cyathiferum, common name Deep Canyon Snapdragon. It is the only species in the genus Pseudorontium. It is native to the deserts of northern Mexico and adjacent California and Arizona. I’ve never seen it before, apparently it is not very common in Arizona according to records in iNaturalist. The leaves are hairy and glandular, the flowers small. Another view of Deep Canyon Snapdragon.
