Help! Need someone to answer this question so I can image!

I have a question or need help I just got a explore scientific 102Mm F7 Triplett ED Telescope… now I just received a field flattener reducer 0.8x which would drop my scope to a f5.6 and focal length 571mm… so my question is under telescope tab settings and sequence generator pro… do I have to change my focal length to 571mm in stead of 714mm in sequence generator pro before imaging??? Thank y’all again

Yes - and the imaging scale for the camera too. It just helps with the plate solving as it can anticipate the imaging scale better.

Awesome thanks for the info…
