Venus and Saturn in the pre-dawn hours 1-21-16

This is my last post of the night, and involves Saturn and Venus. Saturn is on its way up in the pre-dawn sky and Venus is on its way down. Saturn is at an apparent magnitude 0.53 and peaks on June 2nd at 0.00 apparent magnitude. The rings of Saturn are a crown jewel in our Solar System, and viewing them through a large or small telescope is really out of this world.

Venus, on the other hand has already reached its peak brightness on September 14th, at an apparent magnitude of -4.53 and currently is at a -4.00. Venus is actually taking shape and shining quite bright. The last time I did any imaging of Venus (other than the daytime Venus/Moon conjunction here) it was more of a crescent shape. Venus goes through phases similar to our Moon, because it lies in front of the earth and closer to the Sun. As it rotates around the Sun, different phases can be seen from here on Earth.

And in case you missed my previous posts today about Mars, and Jupiter here are the links

Mars - An Amateur Astronomers View 1-21-16

Not only did I take some amazing pictures of Jupiter last night (link here), I also stayed up late enough to catch a couple of the other bright planets, including our nearest neighbor Mars. This was my first attempt at really imaging Mars, and I didn't expect much out of it. Mars is currently at an apparent magnitude of 0.99, and will not peak in brightness until May 22nd at an apparent magnitude -2.06. This is when you should expect some amazing amateur astrophotography pictures of Mars!

Jupiter and the Great Red Spot 1-21-16

Jupiter is putting on an amazing show during the winter months here in the Coachella Valley. The gas giant is currently at an apparent magnitude of -2.30, and gaining in brightness each day until peaking on March 6th with an apparent magnitude of -2.49 for the year. These sets of images show the great red spot and storm bands of Jupiter as it rotates across the night sky. My goal for the evening was to really capture the movements of Jupiter's surface in the span of a night. I think it went quite well, for an amateur astronomer.

The Moon is currently in a waxing gibbous phase, which means its almost a full Moon. The Moon played a small negative factor in last nights observing, but overall didn't affect the images too badly. After this months full Moon, which occurs on January 23rd, I recommend a wonderful opportunity to pull out your telescopes and cameras and view the largest planet in our solar system, as well as 4 other bright planets (Mars, Saturn, Venus, and Mercury) all in our night sky at the same time!

Stay tuned for a future post on exactly when and how to spot Mercury here in the Coachella Valley in the coming weeks. It is currently very low on the horizon at dawn and hard to catch with the mountains and palm trees in the way.

I have pieced together a GIF of this evenings Jupiter pictures showing the planetary rotation and movement of the great red spot. This was a really fun project to put together and I could not be happier with the end results.

Next, we have the images that make up the GIF above. These are all stacked images with Avistack, 1800 frames to produce the final images. Taken with a Celestron Nexstar 6SE and a Phillips SPC900NC webcam.

Here are my final images of Jupiter for the night. I wanted to catch the moons Io and Ganymede, as well as a close up of the great red spot and a bit more of a magnification on Jupiter in general, enjoy!

That is not all we have for today! My next few posts will be about imaging Mars, Venus, and Saturn! I hope you enjoyed my post and I look forward to your comments and feedback via social media and the likes. Clear skies!

Jupiter Ganymede Shadow Transit and Great Red Spot 1-11-16

The seeing here in the Coachella Valley was excellent last night, so I had the opportunity to spend the night outside with clear skies, and my trusty telescope. It was quite cold outside, for the valley anyways, so hot cocoa was flowing like water. These are definitely my personal best images of Jupiter, so far! I was actually speechless while processing the videos, but that was more than likely the cold temps outside. I am quite satisfied with the results and I hope you enjoy viewing them. Clear Skies!

Image details - Each image is a 1600 frame video stacked in avistack with minor wavelets adjustments at the end. The first image is actually a composite of two, one for Jupiter and another with high gain to show the moons Ganymede, Europa and Callisto.

January List of Events in the Coachella Valley

moon and San San Jacinto Mountains
The first month of 2016 will be an exciting start to a new year for astronomy enthusiasts. There is going to be plenty of celestial events, and interesting observations so keep your eyes on the night sky.

Unfortunately, El Nino is coming our way, and that means clouds and rain. Now this may sound great for obvious reasons, such as the drought, but it does not bode well for astronomy and astrophotography. Clouds make it generally very poor for stargazing.

First we have the annual Quadrantids Meteor Shower on January 3-4. You can catch the meteors starting after sundown on Sunday night, and watch them throughout the evening and into Monday morning. The best time for viewing is the actual peak, which starts at 3am and ends at the first light of the day. This particular meteor shower is above average, and NASA is estimating around 80 meteors per hour in areas with dark skies and little to no light pollution.

January 2-6 Spot the space station! Early morning hours seem to be the sweet spot for viewing the ISS in the Coachella Valley. Head on over to Spot the Station via NASA here to see dates/times and other information related to local sightings.

January 9th @ 7:00pm Star Party hosted by the Sun City Palm Desert Astronomy Club, located at the east greenbelt off Donny Circle, just south of Alliance Way in Palm Desert. More info here.

January 10th we have the New Moon, which is a great time to view the galaxies, nebulae, star clusters, and other types of deep sky objects. Without the interference of the Moons glow, faint objects in the sky can be more clearly seen.

January 16th 5pm-8pm Star Party hosted by the ASTRONOMICAL SOCIETY OF THE DESERT, located at the visitors center. Directions and information can be found here.

January 24th is this months Full Moon,

January 27th @ 7:00pm is the monthly general meeting of the Sun City Palm Desert Astronomy Club. Located in the Tahoe Room at the Lakeview Clubhouse. This month, they will be talking about "Hubble and the Sagittarius Star Cloud". More info here.

Jupiter, Io, Ganymede, and Europa 1-1-16

I couldn't contain myself New Years Eve and did a bit of backyard telescoping during the celebrations. With wine bottle in hand, the Wife and I set up the Telescope and listened to the symphony of celebrations being orchestrated  in and around our neighborhood. The seeing in the Coachella Valley was not in my favor, and the fireworks and waning gibbous Moon offered no real help either, but I did manage to photograph a half way decent shot of Jupiter and 3 of its moons. I hope everyone has a fantastic New Years, and cheers to 2016 in the Coachella  Valley!

Equipment used was a Celestron Nexstar 6SE, a Philips spc900nc webcam and a 2x barlow
