<![CDATA[Capturing Comet Catalina]]>

I got the comet but it isn’t what was hoped for – a faint fuzzball in binoculars.

This was Comet Catalina (aka C/2013 US10) in the dawn sky this morning, December 6, with the comet appearing as a fuzzy star below brilliant Venus in binoculars, and just revealing its two short tails in photos. It’s the cyan-colored object near the centre. Venus is the brilliant object.

This image is with a telephoto lens, and covers a little more of the sky than typical binoculars would show. I knew this would be a binocular comet at best, but it’s barely that. This is more a comet for telescopes.

But as the Moon departs the scene and the comet climbs higher the view may improve. Still, if you are pining for views of Comet Catalina and are stuck under cloudy winter skies at home, don’t be worried. You aren’t missing too much. Except …

The arch of the Milky Way in the northern autumn and early winter sky, from Arizona on December 5, 2015. The Milky Way extends from Aquila to the left, in the southwest to Cassiopeia at top right, to Perseus and Auriga at far right, in the northeast. I shot this from the Quailway Cottage near Portal, Arizona, latitude +32° N. The view is looking north toward the celestial pole. Polaris is just right of lower centre. This is a stack of 8 tracked exposures, each 3 minutes at f/2.8 with the 15mm lens and Canon 6D at ISO 1600, with the ground coming from one exposure to minimize blurring. The camera was on the iOptron Sky-Tracker.

This was the view of the autumn Milky Way from here in Arizona last night. Pretty impressive under nearly perfect sky conditions. And then there’s this …

Orion and the northern winter constellations and Milky Way setting at dawn over the Chiricahua Mountains of southwest Arizona, near Portal, AZ. The waning crescent Moon in the west provided the illumination in this dawn shot from December 6, 2015. Orion is just above the main peak at centre, with Sirius, in Canis Major, to the left and Aldebaran, in Taurus, to the right. The Pleiades are setting at right. The star cluster at top is the Beehive, M44, in Cancer. Bands of airglow add the red streaks. The site is the Quailway Cottage near Portal, Arizona. This is a stack of 4 x 2 minute exposures, tracked, at f/3.5 with the 15mm full-frame fish-eye lens and Canon 6D at ISO 1250, for the sky, and the same specs for 4 exposures, untracked for the ground. Each set was mean-combined stacked to reduce noise.

This was the winter Milky Way with Orion setting into the west over the Chiricahuas at dawn. Turn around from looking at the comet and this was the view. So who cares if the comet isn’t too great? There’s lots more to see and shoot. With no snow, no frost, no dew.
