Meade DSI

[Graeme Bluestar]

Hi all,
Wondering if anybody can give any suggestions - I presently have a Meade DSI 2 fitted to a 16" F4.5 Lightbridge reflector. This has been giving good sharp star images, however I recently replaced the camera with a DSI 3, only to find the star images now appeared as a short streak, not a sharp point. Any ideas on what is causing this - maybe something as simple as collimation??

I have same cameras. Sounds bizarre if theres no change to the scope and exposure time or tracking. Post a picture?

Glenn,
I will take some photos with both cameras this weekend and post them up for comparison. Assuming this rotten cloud will eventually go away!!
