An early morning with the planets and the TEC 140.

---

The planets are all lined up in the early morning sky, and the summer atmosphere here in DC can really settle down at night. The Sun begins to rise at around 5 AM, however, so getting up early enough to see the planets means sacrificing sleep. Still, I couldn't resist setting out twice, over the past few weeks, to catch glimpse of Mars, Jupiter, and Saturn. 

First, on June 25th, I marched over to a nearby soccer field with my Takahashi in hand. Seeing with supposed to be better than average, while transparency was a little worse. When I set up, however, I realized that the atmosphere was actually surprisingly turbulent around the eastern horizon. That kept me from getting a good view of either Jupiter or Mars,  which was quite disappointing given how tired I was. When I swung the refractor over to Saturn, however, I realized that the atmosphere was better towards the south. I had a really nice, crisp view of the planet and its rings before wisps of high-altitude cloud convinced me to pack up.

A few days later, I celebrated my daughter's sixth birthday. While hauling stuff to her party, I realized that a little wagon would really help. It also dawned on me that a big enough wagon could carry my TEC 140, together with its tripod, mount, and eyepieces. I pulled the trigger and bought a ​UIDYGGD Folding Wagon, hoping that I could use it to haul my biggest telescope to a nearby field. In summer the leaves are just too thick, and the streetlights are just too bright, to use the TEC 140 in or near my backyard. 

On the early morning of July 11th, I loaded everything into the wagon and began to wheel it towards the field. After about thirty seconds of hauling, I nearly gave up. I was dragging everything uphill, and my back was on fire. I paused, then persisted - and after fifteen minutes, reached the field. It occurred to me that there was no way I could have made it there while holding my telescope case in one hand, and pulling my rolling suitcase - which stores my tripod, mount, and eyepieces - in the other. 

After I set up, I turned to Mars and was rewarded with easily my best view of the planet this year. Not only was the south polar cap clearly visible, but so was a latticework of dark albedo features spidering up towards the planet's equator. Turning, to Jupiter, I was delighted to see the shadow of a Galilean moon, just beginning to emerge onto the planet's western limb. This time seeing really was better then average. It seemed there were more cloud belts than I could easily count, and there was that sensation of infinitely intricate detail that the clouds can have when Earth's atmosphere is sufficiently stable. 

Saturn, however, again stole the show. I've never had a view of Saturn using the TEC 140 that was quite as good as those I've enjoyed of Mars or Jupiter. But this time, with Saturn fairly high in the sky, I was treated to perhaps the sharpest view I've ever had of the planet. Not only was the Cassini Division plainly visible for the entire length of the rings, but I could make out multiple rings - which is rare for me -and the shadow of the rings on the planet was a perfect, velvet black. I also made out a whole slew of moons, and beautifully detailed, turbulent clouds on the planet's creamy yellow-white disk. It was a view that fully justified my lack of sleep - in fact, one of the best views I've ever had of a planet. 

I usually prefer viewing Jupiter and Mars to Saturn, because the appearance of the closer planets changes much more than that of Saturn. But when the atmosphere cooperates, the night sky offers nothing more beautiful - or more hauntingly alien - than Saturn and its rings.
