Nice disks Robert. It appears in the WL image that the details on the left side of the image appear sharper than on the right. Maybe some tilt in your imaging train? You are right, Warren, but I think it may be the reducer is the culprit as well. I tried today (25th April) without it https://live.s...

This is fixable. The screw acts on a slanting slot to compress the etalon filter to adjust tuning. Trial and error to chose which hole to put it in. Mark Townley is the man to explain properly.

Perhaps presenting both the monochrome and colour is an option.

Yes good idea, thanks.

UV filter does block CaK. You can use an IR filter. The Barlow is ok between the module and camera. I have been using this arrangement for several years with an ED80 and ED100. No issues so far. Good luck.
