Thanks Martin,
I should have been more precise,; there is a colour version of the ASI 1600, though it is no longer in production. The ZWO site does indeed quote 17.5 mm, but that also includes an 11mm threaded collar . My question was really about the number and thread sizes needed to link up with the flattener
Sorry if my question wasn't very clear, but thanks for the response.

I'm in the process of upgrading my current setup to one more up-to-date and more portable. The new setup is a Sky-Watcher Evolux 82ED OTA on a Sky-Watcher AZ EQ5-GT Go-To GEQ & Alt-Az mount. I intend this to be an imaging setup, and to that end the scope is fitted with a Sky-Watcher .9x Reducer/Flattener . The imaging camera is an ASI1600MC with a back spacing of 6mm between the camera case and the chip. My difficulty is deciding what spacer combination is needed to achieve the required 55mm backspace between camera and reducer. I wonder if any kind soul has any advice on what spacer combination I will need ?
Thanks in advance for any help,
Roy

Well, the hard work certainly paid off.

Thanks Mark and Paul. The over enthusiastic noise reduction was my way of dealing with very noisy subs - high humidity and quite misty conditions.

That's an impressive selection, I particularly like the image of M101. What are the imaging details?

I managed to capture these two images during a rare clear spell over two nights last week. They were taken with an ASI1600MC pro (OSC) mounted on a SW 200PDS and comprise 25 and 27 subs respectively , each of 300 secs. The subs were captured using APT and were staked with calibration frames in APP.
