I'm planning to upgrade from my Canon 70D astro modified to ZWO ASI533MC to use it with my William Optics ZenithStar 61II. I'm just wondering how to connect the ASI533MC to the Telescope with Flat61 (not the Adjustable one) , is everything included in ASI533MC box or I have to buy an additional adapter to be able to connect it? Also, I'm planning to use the Optolong L-eXtreme 1.25" filter and not sure if that will affect anything with the back focus.
This is my flattener: https://agenaastro.c...ttener-z61.html
