Asi2600mm fan vibration

capacitor

I have only had this camera for a little over a month and at focal lengths around 400mm I have not had any issues. Once I jumped up to about 1300mm I was seeing what looked like uniform star trails even with short exposures of 2 seconds and with guiding at .5 arc-sec. After a lot of trial and error I found I could eliminate the trails by just turning the cooler off. Without the fan running stars were pin-point. Some searching online and I found out quickly that this is not an uncommon issue. Was even more evident when a satellite crossed the field of view and instead of a perfect straight line you could see a very uniform oscillation in the trail.

Coming from the asi533MC pro I never had this issue all the way up to 2000mm focal lengths. Is there a replacement option for this fan since the camera becomes unusable at higher focal lengths. Attached screenshot of star trails with satellite track.

After testing the toric rubber rings, I've concluded that they do not provide a comprehensive solution to the fan vibration issue. These toric rubber rings don't eliminate the direct contact of the screws with the chassis. This is a design consideration that could potentially be improved upon. One possible approach could be to seek out specific fans without vibrations or redesign the fan mount to minimize any contact or proximity with the chassis and components. This could enhance the overall performance of the camera, especially in terms of vibration control.
