The Big Dipper

I headed to northeast Colorado last Friday to see if I could spot the aurora borealis caused by a large Coronal Mass Ejection. Unfortunately with a nearly full moon (86%) I didn't see it. I did play with my modified Canon 60D and got a few shots. This was one of a few shots I did get that was presentable. I was happy with the performance of the camera as I got it last year when we reached the peak of the covid lock downs. I'm looking forward to getting out more to play with the camera later this summer....
Info: Canon 60D modified, 18 - 55 mm kit lens, ISO 1000, 5 seconds at f4.5.

Neat shot of the Big Dipper. You captured the naked eye double star of Alcor and Mizar at the bend in the handle of the Big Dipper (The brighter on is Mizar). At higher magnification Mizar itself is an optical binary and each component is a spectroscopic binary making Mizar a quadruple star.

Excellent focus, as evident from Mizar and its twin.
I would have probably pushed the exposure to 10-15 seconds with the lens you used but that is just my preference.
I had full spectrum modified and stock 60D's at one point. Great little camera for astrophotography!

I think I've read it's really a six star system. At our public star parties, in pre covid days, people would ask about naming a star scam. I would tell everyone to just pick Mazar because it's up all year and easily found. There also that it was used for an eye test

I really appreciate your comments... Yes, I should have exposed longer. At least the learning curve is still going up.

ASTRO is tough, real tough. Longer exposure means more earth rotation.

Nawww....
It means guiding. Then you can go into longer and longer exposures...
Money... money... and more money.
Remember, the skies the limit.

I know guiding is tough, lot of factors going on at same time, guide scope adds weight to mount also. My buddy did all 110 Messier over few years and made a disc for club members

regular guiding getting you close if you're exactly polar aligned which noone is. I just bought a pole master for improved polar alignment. Better check periodic error too. The list goes on. These photos people due are hard but I need acceptability to me
