Nicely done, I'm curious what your delay was between photos?

I set the camera to 2 min between shots and the counter set for 999 shots. That gives me more then enough shots of the eclipse phases, plus it's easy to stop the interval shooting, adjust the ISO a bit as the moon darkens, and get the interval mode back on. This composite is about every 4th frame stacked in Startrails. The Moon moves it's own distance about every 5 min, so you could set the interval to 4-5 min and get about the same results as the photo.

Damn! How did you maintain focus as the moon was moving?

A tripod and the focus for the moon or stars with my FA50 1.4 is infinity, so it's always in focus once you set it.

That's interesting. I had manually focused my DA 55-300mm on the moon at infinity and the photos were blurry. Bringing it in slightly from infinity fixed the focus.

Infinity is different on all lenses. sometimes it at the very end of the focus travel, sometimes a bit backed off. Some lens have an infinity mark and it might be a bit off also. And with a lens like the 18-135wr that have no stop, infinity can be hard to find in the dark. I used the FA50mm 1.4 and infinity is all the way to the end, on my copy. With a 300mm lens infinity for the Moon would be out of focus.

I pre-focus for infinity and the stick tape on it to keep it there.

Focus on a bright star in live view at 10X magnification. That does look pretty good however.

I'm new here, as well as relatively new to astrophotography with my Pentax. I must say that I am finding a great many helpful and creative ideas regarding astrophotography and equipment posted here. That said, perhaps I can get some advice regarding a question that has been troubling me. I'm shooting with an older Pentax *ist DL @ ISO800 employing a range of Pentax telephoto lens. These are carried on a small driven mount at a celestial rate. My problem is the long delay between the taking of my 60-120 second exposures and the camera processing the image (normally taking slightly longer than the exposure itself) and the camera resetting itself before I can start the next exposure in a series.

I've checked the camera's manual a number of times, but don't see anything directly addressing the situation, nor ways around it. I assume this is because most typical exposures are expected to be factions of a second, not minutes. So, is there any camera setting or way to obtain a series of extended exposures that circumvents/delays the camera's handling of new images until the series of shots (5-10 in number) are completed?

You probably have "long exposure noise correction" on, meaning that for each light frame, the camera will take a dark frame of the same exposure duration and subtract that dark frame from the light frame.

In the ist DL camera menu, go to "Custom Setting" and disable "Noise Reduction" in the second line from the top.
