Do you use mirror lock-up?

I usually do but I forgot to this time. It makes sense to use it.

Yep - this is what I do. If you use an intervalometer, the camera needs a short delay between the end of one shot and the start of the next. If you use "continuous" drive mode then you can lock the shutter button and it's a much faster shot-to-shot rate. You do need a remote shutter release that has the lock slider on the shutter button (but that's not an expensive item and most "wired" shutter releases will have a lock slider.)

I tried doing star trails with an intervalometer but the delay caused the trails to be dotted lines. Now I only do continuous unless I need exposure times more than the camera can do by itself.

Write speed shouldn't be a problem since these are long exposure times. Any modern camera can buffer the last frame taken and write it the card while capturing the next frame. As long as it can write a frame within the 30 second time then you should be good. Most cards can write a frame to the card within a second a couple of seconds.

I'm guessing most DSLRs on the market can probably buffer at least 5 RAW frames. Higher end models have larger buffers and can handle many more. But given the 30 second exposure time, it will never need to buffer more than a single frame.

I don't think you know what I'm talking about. You probably are using a much newer camera than my XSi 450D . I can do a 30-sec exposure but at the end of the exposure it may sometimes take 2-3 secs to finish writing to my card , meanwhile manually I have already tripped the shutter for the next exposure . If I use a slower card it will not allow next exposure to trip until the previous exposure has finished writing to the card . A faster card will eliminate that wait time . Being as educated as you are you should know what I'm talking about . Sometimes I don't read all your post cause they are such long replies . I feel like I'm at a college class trying to listen to a professor explain a simple situation . Sometimes replies need to be short, simple and to the point ....

No, not needed for WF long exposures . Hook up to a high power lens or scope then yes .

For wide angle shots you don't need mirror lockup, the only time I use that is when I'm taking exposures at 150mm or longer where the vibrations of the mirror going up can cause issues.

Got it. Thanks.

Are you using "continuous" drive mode, or are you using a remote shutter release to trigger each frame?

I've never owned an XSi (based on DIGIC III). My first EOS was a T5i (based on DIGIC IV). So perhaps your model is different than new models.

However, I've also noticed that if I use a a remote shutter release then the camera wants a couple of seconds between the end of the last frame and the start of the next frame (e.g. programming an intervalometer with no delay between frames often results in a missed frame). But if I use "continuous" mode it goes from one shot to the next and happily writes the last frame while recording the current frame (simultaneous).

I tend to write based on experience of helping (often frustrated) people. I notice which missing details seem to trip-up people and make sure I include them. I often get people who go out of their way to thank me for writing things out clearly rather than leaving too much to assumption. If I'm describing something you feel you already understand, then there's no need to read it through. But if a person doesn't already understand it, they are happy for the information.

Continuous mode while using a Remote at same time .

Yep - I had my 15 minutes of APOD fame 5 years ago, kinda cool http://apod.nasa.gov/a​pod/ap110805.html (external link)

Both of those composites I mentioned here are bw! material for APOD

the main advantage of using mirror up or shooting from live view ( default mirror up) is that it lessens
camera shake from shutter release. all you hear is a tiny click instead of a loud kerchunk ;-)a

so for that single reason alone, I always prefer to shoot from live view

Shot a few hundred and got about a dozen, plus satellites. My widest angle was a 28-135 at 28 with a crop body. So. I just aimed where I thought they might go. Saw 65 Thursday and 8 the next night. This was my brightest and longest capture.
