hi
I use a DSI pro camera and encounter some problem with images.
on my pictures I see some regular and parallele lines (allways same direction).
Is someone can help me with this?
thanks
Hi
In the Envisage software there is a setting once you press the CNTRL button, called Line Delay. For the Pro I have found between 2-6 is a good range. For the Pro II - seems best at 2.
I've seen lines at different times and I believe they are also due to other factors
1. Appropriate darks - if you take darks at one temp and the temp changes during an imaging session you can see a range of effects. I take lots of darks at different temps and keep a library of them. Keep the dark temp limit setting below 5 to reduce variation
2. USB 2 - I have had problems with noise and striping using USB 1.1. I stil get problems with USB 2 from time to time if I run other things off USB at the same time. A lot of folk recommend getting a USB 2 hub with separate power source
3. Exposure time - you will see far less stripes and other noise for that matter if you take longer (or many shorter) exposures
Thanks for that. The lines were on prime focus and 2x barlow moon shots taken with an 8" F5.5 and DSI Pro with filter. Sometimes the are there at other times not. Mind you, this is my first foray into CCD Imaging.
