I am not sure I understand your statement. Does it mean you are making an adapter now or you are waiting you get requests? This is my request!
36mm filters are MUCH cheaper than 2 inch filters. If an adapter was available, a lot more people would buy an APS-C cooled camera such as the 2600MM.
Making a "2" -36mm" adapter makes more sense than a "2"-1.25" adapter". 1.25" filters will vignette A LOT on an APS-C camera. 36mm filters will not be a problem with an APS-C camera. That would save a lot of money for ZWO camera users and make them buy more ZWO cameras like the 2600MM!! I would buy those adapters right away!! 7 of them!! and buy the 2600MM.
