I am trying to correctly choose the appropriate astrophotography equipment for my Takahashi FC-100DZ. I think I have an idea of what I want/need but would like to get some other eyes on it to be sure. I currently have a Tak FC-100DZ and intend to use it with the FC-35 reducer as well as the Tak flattener. Native the Tak is f/8 so 100mm lens and 800mm fl. The flattener is 1.04x (f/8.32) and the reducer is .66x (f/5.3). Astronomy tools shows this seems to cover me for average to good seeing. Of course with good seeing the limiting factor will likely be the telescope resoltuion.
I've been on the fence about whether or not I should purchase a monochrome or color camera and have been leaning toward the ASI-2600MC but I could be persuaded otherwise. I only lean that way for convenience but like the idea of monochrome and the other things I can use it for. One of the things Im not sure about is back focus. The ZWO website talks about how to get the proper back focus (55mm) for most telescopes but how do I figure that out for my fc-100dz?
Any other thoughts or suggestions as I go through this? In town where I live, and using DarkSkyFinder, the skies are bright yellow. I have a farm about 30 minutes away and the skies are dark blue there, so much better.
