Just substrackt from the 60,4mm back focus length the camera (17,5mm) so you see that you have 42,9mm left for the UFC.
#2459132 is 4,1mm
#2459110 is 13mm
#2459115 is 2mm
These would be the Items you´ll need anyway but still 23,8mm left to bridge with extenders like:
2459141 is 5mm
2459145 set to 18,8mm
Important note on Hyperstar-Adaptation
The distances for adapting a camera to the Hyperstar system must be done with a precision of +/-0.3mm or better, otherwise the image quality will suffer. Please take a look at the following image showing the necessary Backfocus.
Example: A Celestron C11 has got a backfocus of 59.7mm; in addition, the focus shifts 0.66 in the extrafocal direction, if you use filters with a thickness of 2mm (as they are usually used for 2"/M48-housings). As a rule of thumb, a filter moves the focus in the extrafocal direction for 1/3 of the filters thickness. Substract the flange focal distance of the camera from this value (runded 60.4mm). The remaining distance is adjusted by the UCF and its adapters. If you aren't sure, please let us know which Hyperstar and camera you will use, when you place an order.
