Help with 60D "Busy"

Hello all-

I just joined up. I'm at my wit's end. I was doing some astrophotography a couple weeks ago and I stared getting that giant, non-blinking BUSY message on my LCD. I've been doing my research, and I can't come up with a reason for this message. Maybe somebody can help. Here's the facts, ma'am:

Full Manual mode.
Noise Reduction is OFF.
Single shots only, no bursts.
Almost brand new low-level formatted SanDisk 32gb Ultra class 10, 80mb/sec.
No Temp alerts, 55 degree F ambient.
Live View on full-time (it was so, so dark) and LCD was against body, not articulated. (Rookie move for astro.)
Shutter speed range 20" to 30".
ISO range 2500 to 3200.

So, after taking about 25 shots, I suddenly start getting roughly 25-second BUSY message on my LCD. After I finished my 5-frame pano, I lowered my ISO and shutter a tad, and the message went away. It was really acting like NR would behave, but NR was OFF. But then, without changing any settings, it happened a few more times -- randomly. I've taken a few hundred photos since that night, and no more BUSY message. I've been continuing to use the same SD card, but shooting at lower ISOs and shutter speeds.

I can't figure this out. Do any of you think it could be the SD card? I mean, like a faulty/iffy card? I don't know how the 60D firmware handles card writes (well, card write errors.) Anybody have any ideas?

Oh, here's the pano: https://flic.kr/p/VNor​vm

Thanks,

There's more than one type of noise reduction setting, high ISO and long exposure, page 254 of the manual. Symptoms seem to indicate long exposure is still enabled.

Holy smokes! You kinda nailed it...

I had disabled NR within a day or two of getting the camera, but I did a reset a couple weeks ago, which must have re-enabled the high ISO NR. But I checked it anyway. I thought the first of the two noise reduction menus turned off NR altogether, and the second menu only chose the type/strength of the NR. Actually, the Long Exposure NR was disabled, and "Off" was at the top of the menu. But on the high ISO NR menu, "disable" is at the bottom. No wonder it was acting exactly as if NR was enabled... I had it set to "standard." Is the fact that I'm a programmer and I would *never* write an interface that way a good excuse?

Thanks a million, old vultureface! And you too, Mark!

I love this place!

Nice pic too

Just so you are aware, there is no such thing as High ISO NR off/disabled. It is just a setting they give you to reflect something lower than the low setting. There is always NR being performed even at lower ISOs like 1600 and 3200 on the JPG images (embedded or otherwise).

Agreed.

It also shows up on the RAW file if you process in DPP.
