I have a local buyer interested in purchasing my Takahashi FC-100DF. I used it strictly for visual but his intended purpose would be AP. His camera is a ZWO ASI2400MC Pro. He's asking what adapters/flatteners he would need to make this work and I have no idea. He's not on CN so I offered to try to help. Any assistance would be greatly appreciated.

 

Thanks.

Here's a link to the Tak FC-35 reducer which is made for the Tak FC-100DF: https://takahashiame...35&_ss=e&_v=1.0

 

No, not cheap.

 

And here's the system chart for a Tak FC-100DF using an FC-35 reducer:  https://cdn.shopify....df?v=1657737288

 

It looks like the required back focus -- the distance from the reducer's threads and the camera's sensor -- is 72mm. So the buyer would have to make sure he uses adapters/extenders that produce this distance. The camera comes with multiple extenders/adapters but inexpensive ones are also available from resellers if he needs more.

 

I couldn't find a flattener made for it.

Thank you for the response. While I understand the benefit of faster, at native f/7.4 is a reducer necessary? I'm assuming it is. Is there a less expensive brand reducer that would work?  Thanks again.

Yes, either a reducer or a flattener is needed… otherwise the stars will be increasingly malformed away from the center. A camera pics up way more than what our eyes can see. I suggest you give a call to the good folks at Texas nautical (Takahashi America) because they know way more than what can be found on their website… there may be less expensive options. Good luck!
