Vega is the 5th brightest star in the night sky and is located only 25 light years away. Epsilon Lyrae, otherwise known as the “double double” appears as four stars at high magnification through a telescope. Hints of the piercing white and crystal blue from Vega can be glimpsed through a telescope but it’s true elegance is revealed through imaging.
The Saturn V Rocket was feeling a little lonely so I bought a companion. The LEGO Lunar Lander is a wonderful piece to commemorate the 50th anniversary of Apollo 11. Building these models gives an extra sense of satisfaction seeing them displayed. This will eventually be making it’s way to my desk at work come August.
People image the night sky for various reasons. My two main goals are to share a small part of my experiences with those who may have an interest in amateur astronomy while also showing people the glory of God by way of His most magnificent interstellar creations.
Few objects check off both of those boxes as well as M13, the Hercules Globular Cluster. This “cloudy” cluster of hundreds of thousands of stars is one of the best shows our galaxy has to offer. Through a telescope, it appears as a dense core with fine pin point stars becoming more apparent as your eye moves slightly away from the core. What I did not expect from this imaging session was how prominent the colors of M13 would be. It’s core shows a gorgeous mix of white, amber and blue stars that appear from our perspective to fuse together from it’s gravitational lock.

Having just gotten into astrophotography, I am beyond pleased to show the results of my latest imaging session of M81 and M82. These two galaxies have been a favorite of mine since I first observed them roughly 10 years ago. At a distance from Earth of 11.8 million light years, the beautiful spiral arms of M81 span about 90,000 light years with the galaxy containing roughly 250 billion stars. But, my favorite out of these two is M82, the Cigar Galaxy. Nearly 18 million light years away, it’s complex core reveals sharp divides and interesting colors that are the result of rapid star formation. Galaxies such as these truly reveal the glory of God and his hand in creating the universe.

Clear summer nights with low humidity are a hard thing to come by. With the forecast looking good, I jumped at the chance to “stretch the legs” of the SkyGuider Pro and do some observing of the Messier List.
Less than a month into using the SkyGuider Pro, I couldn’t be more pleased with it’s performance and quick set up. Yet again, I trained it on M81 and M82. This time bumping the exposure up to 2 minutes and taking the ISO down to 800. Results from over 1 hour of exposure time will be posted in the Astrophotography page.
With the SkyGuider Pro and DSLR tracking and imaging, it approached midnight and several Messier objects began to rise in the Southern sky. As the DSLR shutter open and closed, I brought out my dobsonian telescope and quickly found M4, which was a fairly bright globular cluster that revealed some fine detail. Next up were my two favorites of the evening, M6, the Butterly Cluster and M7, Ptolemy’s Cluster. Of the two, I was most impressed by the simplicity and elegance of the Butterfly Cluster. From there it was a race to see how many faint Globular Cluster’s could be viewed before the DSLR was done shooting light and dark frames. After moving the telescope to see above the tree line, M69 and M70 were my final targets of the night. Both of the these were very faint and if not for clear and steady skies with low humidity, wouldn’t normally be visible from my house that low on the horizon.
Failed attempts at the Trifid Nebula, Sagittarius Star Cloud, the Eagle Nebula and M55 show that I will have to travel to the Blue Ridge Parkway for these this Summer. Some enjoyable views of Jupiter, including the Great Red Spot, Saturn and the Ring Nebula made for nice breaks between the hunt for faint Messier objects. With observing done, I moved back over to the SkyGuider Pro and took the Bias and Flat frames for post processing before packing up and heading inside for some rest around 2:30 am. I don’t know how many night’s like this I’ll get this summer and am glad I put the clear skies to good use.
As for the Messier List…5 Down…7 to go!
After months of research, I have purchased my first tracking mount for astrophotography. Many websites, forums and youtube channels led me to the iOptron SkyGuider Pro as an entry into this new aspect of astronomy. I plan on writing and filming a full review in the coming weeks but until then my initial impression after a few nights of use is that this mount is easy to use, very portable and solid in it’s performance.
Below is the end result of my first processed image using the iOptron SkyGuider Pro. The Owl Nebula with it’s “eyes” looking out and M108 float in the void of space surrounded by hundreds of stars. Given the size and faintness of these two objects, I was really pleased with the results of my first imaging session.

Leading into tonight and after nearly 2 years, I had observed 71 of the Messier objects. The remaining 39 objects consisted of 3 Nebulae, 3 Open Clusters, 7 Globular Clusters and 26 Galaxies. It is those last galaxies that give me the biggest mental roadblock and there is no cluster of galaxies more daunting than those in the Constellation Virgo.
8:45 PM to 9:25 PM: Failure in Ursa Major
The evening was originally going to consist of objects in and around Ursa Major. I had a list of 6 targets planned but seeing conditions and light pollution only allowed me to view M106 in Canes Venatici. No other object would show a hint of detail. Frustrated, I noticed that most of Virgo had risen above my neighbors tree. I had not been planned on jumping into this daunting region of galaxies tonight, but thought it was worth a shot.
9:35 PM to 10:45 PM: A Surprisingly Pleasant Trek through Virgo
Starting in the northern portion of Virgo led to initial discouragement with objects such as M96, M85 and others not showing up. At this point, I was starting to become frustrated. Of the 10 objects I had attempted to observe thus far only 1 had been visible. For all others, the star patterns matched perfectly with my charts but where the galaxy should have been a dark void existed. At this point, I’m thinking I will have to go off site to darker skies for more Messier objects than I had bargained for.
I decided to give a few more attempts before calling it a night but this time started from the southern point of Virgo. To my surprise, two galaxies, M59 and M60 appeared in the eyepiece. Moving up Virgo, I used M89 as a central point to jump to M90 and M58. Star hopping took me to M87 and then up to Markarian’s Chain, M84 and M86. One final sweep through Virgo revealed M88. With Ursa Major a bit higher in the sky and observing conditions improved, I moved back over and was able to catch M102 before concluding the night.
Galaxies such as M88 and M90 at +9.36 magnitude were pushing the limit of what I was comfortable verifying as observable targets through my skies. Using 96x magnification and averted vision helped with these observations. Others such as M87 were surprisingly easy to view. Depending on the size and surface brightness of the object it appears the limits of my sky and telescope are around +9.5 magnitude. What I thought would be a nice evening in Ursa Major ended up being a surprisingly productive evening in Virgo. It appears I’ve overcome my Virgo phobia.
