 Waning Moon on the first autumnal morning of the year. The weather has been stormy over the past few weeks, but this morning the clouds cleared and the seeing promised to be good. I woke up at 2:45 AM and walked out the door by 3:20, hauling my APM 140. As I reached my local park, it dawned on me that conditions were essentially perfect. The sky was wonderfully transparent, the temperature was perfect, and there was a thin misting of dew on the ground. The rabbits and fireflies that used to give the park such a magical air, however, have largely disappeared (for now).  Observing Moon and Mars in the field, and at home after my little guy woke up. It was a special morning for more than one reason. The Moon had just passed in front (occulted) Mars, and the two worlds were still right next to each other in the night sky. It was a stunning sight as I set up the APM. Then, when I wheeled the big telescope around to have a look at the Moon, I was just floored by the spectacular, razor-sharp detail. Rilles and craterlets snapped into view as I've never seen them, and I thought I could actually pick up gradations of color on a Moon that has always looked monochrome to me.  False color in this image is entirely a consequence of my iPhone. It was easy to get lost in that view, but I had a job to do: observe Mars as it approaches opposition. Now, it's around five weeks away - hard to believe! - and wow does the planet look big and bright. The APM revealed it in spectacular detail, with Syrtis Major huge and dark on the planet's surface, arcing north from a south polar cap that now seems small (but bright), with Nodus Alcyonius obvious nearby. It was easily the best view of Mars I've had. By 4 AM the view softened a bit, as a turbulence entered our terrestrial atmosphere. I think I noticed a hint of the planet's rotation between 3:45 and 4:45 AM; Syrtis Major seemed just a bit offset from where it was when I set up.  Everything must have a beginning.... I knew my iPhone would never capture even a half-decent image of the view, and I kicked myself for not bringing a sketching pad. Still, I have an app called "Paper" on my phone, and I used that to quickly just down what I could easily see. An enormous amount of detail is missing, of course, including many subtle grays south of Syrtis Major. Yet I'm hopeful that I'll get better at this, and I could tell that it helped me observe more closely and carefully.  Someday - someday! - I'll take better pictures. By 4:30 AM or so, the highlights of the winter sky had climbed above the horizon. Of course, I had to have a look at Orion. To my surprise, six stars were visible in the Trapezium - a first for me, if memory serves. Through the APM, the nebula looked about as impressive near the light-polluted horizon as it does while near zenith with my Takahashi (or maybe even a little better). Rigel B was much easier to spot than I can remember, and the Pleiades were just spectacular. Venus, also rising in the east, was lost in atmospheric turbulence. But still, I observed its half-disk for a minute or so.
I've praised it before in this space, but wow - I cannot say enough about this APM refractor. There are times when I've fantasized about selling all my gear in exchange for an Astro-Physics refractor - something truly high-end. Yet I just can't see how the APM can be improved. I see less false color with the APM than I do with the Takahashi - even with the Takahashi's focal extender screwed in - and the detail, contrast, and color I can see on planets is just otherworldly (sorry). Bright deep space objects are a joy to observe, and the every last detail on the telescope - from the focuser to the dew shield - is a pleasure to use. Like my TV-85, there's something magical about this telescope. It's a true keeper. Also deserving of praise: TeleVue Delos eyepieces. They are, without doubt, the best I've used in terms of clarity, contrast, and comfort for my eye. Maybe I'll get another come Christmas.
