Sinus pressure killing my ability to sleep. I'm going to be a snot zombie today.

First light for my new ZWOASI120MC cmos camera which I got for Christmas. We've had the mono version for years and I loved it, but it stopped running on my Windows 8 laptop and nothing we tried would stop it from crashing each time I plugged it in. So I haven't used it for a very long time and it's in fact now used as a guide camera in our observatory set up! I got the colour version for Christmas but hadn't even plugged it in because I assumed I would have the same issues that I had with the older camera. Today I just figured I'd give it a try and to my astonishment it worked!

Taken from Oxfordshire, UK with a William Optics 70mm refractor, and the ASI120MC camera with a 2x Barlow attached. The whole assembly was on an EQ5 Pro mount on a permanent pier.

2,000 frame video shot using SharpCap, the best % frames were stacked using Autostakkert! 3 Beta and wavelets adjusted in Registax 6. The image was then processed in Lightroom, Fast Stone Image Viewer and Focus Magic.

Ongoing series of double-exposure silhouettes I'm working on, using my iPhone with the Hipstamatic app. I can't see the first image when I take the second one, so lining things up is a bit hit-or-miss.

Despite being plagued by high cloud yesterday evening I managed to get this image of the waxing evening moon.

The sweeping curve of the jewelled handle is visible, emerging form the terminator near the top of the image.

This is actually the sweep of the lunar Jura Mountains interfacing with the adjacent "flat" plain of the Sinus Iridum or Bay of Rainbows.

Imaged with an 80mm refractor and a Nikon D5300.

This image was again captured on the evening of 02.12.14. Close to part of the terminator in this 10.4 day old moon the image shows many features within the Sinus Iridum/Mare Imbrium region. The starkness of lunar day and night is very evident with the rising sun picking out a lot of highland detail with sharp shadows being cast by peaks onto the lunar plains! The angle of the rising sun has also nicely highlighted many wrinkle ridges - looking like giant creases on the moon`s surface.

Sinus Arabicus

The front seat of this 1952 Dodge Meadowbrook at the abandoned Pearsonville junkyard was filled with spare interior parts and other debris, so I slung it all into the back seat. Unfortunately, it created a terrible toxic cloud of dust that I accidentally inhaled. Within 24 hours I had a terrible sinus Infection that lasted a month. Anything for art.

Sinus

This field of view presents a lot to explore. The dark circle in the upper left corner is Copernicus, which spans 58 miles (93 km) in diameter. The low angle of illumination accentuates the ejecta blanket that surrounds the crater. Many chains of smaller craters are visible, which are secondary craters formed from debris released during the formation of Copernicus.

Numerous secondary craters can be observed scattered across the faint remnants of Stadius Crater. The outline of its 43-mile (69 km) rim is barely visible as it rises from the ancient basaltic lava flows.

Eratosthenes crater measures 36 miles (59 km) across and has a depth of 2.2 miles (3.6 km).

Sinus Aestuum, which translates to Seething (or Billowing) Bay in Latin, is the anchor target in this view. It features a nearly smooth surface of low-albedo basaltic lava, marked by a few minor impacts and some wrinkle ridges. Pay attention to the darker highland area in the southern part of Sinus Aestuum.

Mons Wolff reaches an elevation of nearly 12,000 feet. Mons Ampère stands 1.8 miles (3 km) tall, while Mons Huygens rises to 3.3 miles (5.4 km).

Observe the volcanic dome near Gambart C crater, which reaches 383 feet (117 meters) in height. (Measured with NASA's Moon Trek)
