=MsoNormal  Slipping during imaging session. This issue is that the filter has started to slip when imaging. The filter is not lined up with the camera sensor and shows a line in image. When I manually rotate filter it centers back up and image is ok, but after about 5 300 sec images it starts to slip and filter moves and there’s a dark edge of on image showing the side of filter wheel filter frame. Any ides on how to fix tks

You can recalibrate it and see if that fixes the problem. If it is new, just return it and get a new one and not aggravate yourself over it.

I have had similar issues in the past. There is a setting in the driver or your acquisition software that will tell the filter wheel to move in only one direction. I find this setting makes the filter wheel perfectly consistent. I have had this problem with filter wheels from other manufacturers as well.

Does it have 7 filters in the wheel? You could be unbalanced if there isn't a full filter set in there.

Rick, the only time I've ever had mine not work correctly is when a filter was screwed in too far and it was scraping on the other side. I've never had it move out of position once it was set but would be curious to know what the fix is when you get it.

@Rick Fair I have the same EFW with screw in 2” filters and I’ve only seen this kind of behaviour only when the wheel is unbalanced just as Brian suggested. Did you try redistributing the filters more evenly around the wheel?

I had the same problem and reason in my case was, that I had 2 empty slots in the 7x2" and did not use them opposite of each other - so a disbalance in the filter wheel pulled the wheel down leading to the same effect.

I had a similar issue with EFW-5, but the problem was in the non-standard filter (too thick), after the filter’ s replacement works fine.

If you add a thick ring, you could change the mechanic position of the wheel or rotate your optic train in the eyepiece holder. It could help to change the move of your filter wheel. It is just an idea.
