Hello,

Your bi-directional CFW3-M/L filter wheel is not always consistent and it's difficult to get consistent flats because of possible backlash in your filter wheel even though your advertisement of your filter wheel says it never have issues with backlash but it does have issues. Please allow us to choose direction of spinning carousel in your filter wheel assembly like only one direction (CW or CCW) or bi-directional by making simple changes to filter wheel firmware. ZWO made a change in their firmware to allow users to choose type of direction of spinning their carousels. I hope you will do the same.

Thank you,
Peter

Hello,

Sorry for using your topic, but I was opening a new one with the same question.

If someone can, please take a look at the attachment, I believe that what is causing this issue is a not perfect wheel (re) center, and I think that changing the filter always in the same direction can be much better.

Thank you very much

There is no reason for bi-directional movement of the carousel. We are not in a hurry to move to the next available filter as quickly as possible. It's much more important to get the best possible image even if it takes a few seconds longer to move to next available filter by moving in same direction all the time.

What good is it to buy the best camera in the world when the filter wheel is not landing in the next position accurately?

Please fix it!!!!!!

Can you tell if this option is being considered in the near future? If not, is there any chance that the QHY team will let me change the Firmware and the ASCOM Driver to implement this funcion?

Thanks
