Crescent Moonrise in Conjunction with Dabih (Beta Capricorni)

I was taking my dog out at 5:50am this morning and noticed a slim crescent moon rising over the apartment buildings next door. What luck! Another example of how owning a dog is good news for skywatching because it gets you outside every couple hours or so.

I didn't notice it at fist, but the moon was right next to a star in the twilight sky (more apparent in the longer exposures). I looked it up using Stellarium, and it appears to be Beta Capricorni, traditionally known as Dabih "the butcher." (Every time I say that I think of Dobby the house elf).

I shot a variety of exposures, and stacked the moon twice in Registax. Here are my best shots with acquisition details:

2 sec, ISO 200, f/4.5, 75mm, 6:02am facing SE
21 subs stacked in Registax, each ISO 200, 1/250 sec, 300mm, f/5.6
21 subs stacked in Registax, each ISO 200, 1 sec, 300mm, f/5.6
