SWAP Filter Drawer OR WHEEL FOR 21MM SPACER

dhmiller123

Hello I am currently using a 2600MC Pro on a Skywatcher Esprit 100 ED. The last spacer in the imaging train in front of the camera is a 21mm spacer with 42mm on the female (front/telescope) side and 42mm male on the camera side. I want to swap this spacer for a ZWO filter drawer, also 21mm, but the ZWO 2-inch Filter Drawer includes M42 * 0.75 external thread (camera side) and and M48 * 0.75 internal thread (telescope side), not 42mm like the 21mm spacer. Please tell me exactly how to adapt the ZWO 2" drawer so it will exactly replace the 21mm spacer that came with the 2600MC. DO you sell this adapter or do I need to find a 48mm to 42mm female adapter of some kind.
Also, the ZWO 5- position electronic filter wheel is also 21mm and would it also swap with the 21mm spacer that came with the 2600, or do I need also some type of adapters if I were to prefer the filter wheel? And when will these products be available again in the US of A. THANK YOU.

Yes but the last spacer in the imaging train in front of the camera is a 21mm spacer with 42mm on the female (front/telescope) side and 42mm male on the camera side.

DO you sell this adapter or do I need to find a 48mm to 42mm female adapter of some kind. The filter drawer has a different size thread than the 21mm.

yes you need the M48-M42 adapter for your telescope side

I do not understand your comment: "Also supply the the new 55 solution by the new 36 filter wheel". What exactly do you mean? And will the threading be exactly correct to substitute the 5-position filter wheel for the 21mm adapter that came with the 2600MC Pro?

IF you have the 2'' 5-position filter wheel

Yes, you have sent me that picture twice already but you did not explain your comment, which I do not understand. Please respond to this question: "Also supply the the new 55 solution by the new 36 filter wheel". What exactly do you mean? What "55 solution" and what "36 filter wheel " are you referring to?**

And will the threading be exactly correct to substitute the 5-position filter wheel for the 21mm adapter that came with the 2600MC Pro?
