While imaging saturn - I have been getting a lot of images that appear to be ragged and jagged - any clues as to how to fix this - I am using a DSI Pro II (BW) with an LX90.  Thanks.

Here is an image of Jupiter that shows the same effect - Every other row of pixels appears dark.  About 90% of my images show this effect.  Any suggestions?

Thanks

Bob

your imager has the capability of a resolution of 752 x 582 pixels.
This image yo have posted is 90 x 81 pixels. It appears you are using too low a resolution.

Actually that is a cut out of a more complete image - the posting would only allow 128 k to be uploaded.

Barbara I also e mailed you this but ill post it here too.

Barbara
this is called interlacing and if your imager isnt set right it can and will happen as you see.
Planets are more difficult to shoot with the DSI  imagers but can certainly be done.First off open up Envisage then hit the ctrl button.
set the line delay to 1 0r 2
This is the setting for 1` second exposure or less.
Adjust exposure time accordingly
May be as low as .250 seconds or faster.
open ctrl panel again and select auto color or white balance.
Make sure you have the exposure time set low not to born out the planet sphere
Manually adjust the histo to have the planet look its best.
Then you should be all set.
If the interlacing pops up again you can de interlace it is PSCS or PSP.

If you need further help please feel free to ask.
