Astro Imager's filter wheel question

I just purchased one of these 5 position manual filter wheels. I'm
wondering if there's any way to reduce the wheel tension so it turns easier.
Anyone know?

Thanks,
Jon

I just purchased one myself and I can see what you say about the
tension. I don't know how to change the tension.

The positive lock and tension during turning appears to be an
astrophotography feature and not a bug.

Although the tension and positive lock may jar and offset the fine
tuning of your tracking, I believe it is intended to always register
the position of a filter with respect to a CCD chip in exactly the same
place and orientation. That way flat-fields made earlier in the
evening using more than one filter will always register the optical
defects in the filter at the same location. An error in the flat-field
registration of the filter cannot be corrected post-exposure.

Conversely, if tracking of the image is jarred slightly between
exposures as a consequence of rotating the filters in the filter wheel,
the digital images taken through each filter can be easily
re-registered post-exposure by using software.
