Closeup Shot of Lunar Surface
Nov 14, 2013 16:47:31 #
Going back over some of my old images that I have basically forgotten. Here is a shot of the moon that was taken back in 2005 with a 14 inch Meade telescope operating at f/30 (12,600mm FL). I used at the time a small video camera purchased from Orion Telescopes and a frame grabber. This is a stack of 125 frames from the original that was saved on a VCR tape. A long drawn out procedure at the time but it worked. Now we have better means of taking these images that is a much easier task.

This is very cool, but even cooler is what you had to go through to get this image. Thanks for sharing.

Nice capture of the Straight Wall
This is my best shot of the Straight Wall after many, many tries. Thank you.

It sounds difficult but actually it was not, mostly time consuming sorting through all the images to pick the very best of the shots to stack.

Jerry could you share ideas on stacking digital images to obtain better sig/noise? Thanks for your post.

Basically it means taking as many images as possible and with the object centered with very little movement between images. Watch carefully for drifting in the frame, eg, if you have 100 images and the first frames line up each time but let's say you notice a very slight drift upward in the field of view. By the time you get to the 100th frame there will be a noticable difference.
Next, you will need a good stacking program. I use Registax (free) and it does very well. It comes with a tutorial so you can read the detailed info on how to stack images with their program.
One thing I failed to mention, some objects, Jupiter in particular rotates so fast that you are limited to about 10 minutes worth of exposures, anything greater than this will result in blurring of the image surface details.
I hope this helps. If you have any further questions do not hesitate to ask.

Thank You Jerry for your time to reply. I will surely apply my self to learning more and attempting this in the future.

Amazing picture, it doesn't have that "fake" look I see with many stacked moon images.
