This is a pic I took last Thursday night. Its 30-5min images at ISO 800 using a Canon 10D and a FSQ-106 @F8. It was processed in Images Plus and Photoshop. The images is 50% size.

Thanks,

Nice one Mark. Just when I start to catch up, you raise the bar another couple of notches;-) 30-5 minute images! That is a lot of images. Did the 10D battery last that long or did you have to use more than one battery.

Excellent image on a difficult subject Mark! I'm very envious .

Mark,
I recently read a discussion on a link from the Yahoo digital-astro site that discussed the effect of series of many shorter frames vs. fewer longer frames. It seemed there was advantages to both.

The longer frames added significant noise (Depending on cooling, CCD type etc) after extended imaging. ON the other hand, adding many shorter images added a certain type of noise each time you added another image.

Question: Have you found the upper limit on the 10D where one more additional image will add more noise than image improvement. (clearly - 30 frames works great).

Hi MArk.

Excellent image! What mount/tripod setup do you have?

Thanks for the image!

Very, very nice Mark!!
