Well, I had time and the skies were clear so I shot a few familar objects with my 8 bit CCD camera and an Orion 120 short tube achromat. I just added a guide...
If I played with the monitor settings, quite a bit of textured structure could be seen in the spiral arms, particularly in M51. M101 looked more ragged, but...
Shot 20 200 second images of M51 before the moon rose last night. Also improved upon my guiding by working with the 80mm guide scope at f/22. More images...
Thanks, Ray, learning this stuff has been great fun, though I do see a problem. Not unlike aperture fever, I now find myself contemplating a 16 bit camera...
Took advantage of the clear skies here in Livermore over the holiday weekend. Each image is made up of 25 or 30 @ 200 seconds exposures. 12cm achromat @ f/5,...
Interesting thought and one that might not have been discussed here but what difference does a graphics card make in image quality? I know there has been some...
Hi Mike, I like the ATI Radeon series cards... the 9600 Pro has 400 Mhz DACs and is more than what you would ever need for 2D image processing and can be found...
