 It is important to note that before mounting the above adapter combination, the long M48 adapter, usually present on the reducer, must be unscrewed to expose the M76 thread.
+**Note:** If the off-axis guider is not used, a 20mm M68 extension must be used instead of the 10mm extension.

 As mentioned earlier, the working distance from the M78 thread is 77.5mm, with the camera including filter wheel, filter, and off-axis guide having a back focus of 56mm. The remaining 21.5mm is bridged by the above adapter combination.

-We also have a [[https://www.baader-planetarium.com/en/baader-cool-ceramic-safety-herschel-prism-markii.html | Herschel Prism Mark II from Baader Planetarium]], which allows us to observe the sun in white light with excellent quality. The Herschel prism can be equipped with different filters, allowing it to be configured for visual observations as well as camera observations with very short exposure times. Details about the Herschel prism and its operation can be found in the associated [[en:ost:telescope:herschel_prism | article]].

-The Herschel prism can be used in many different configurations, for example, with and without a Barlow lens. However, the standard procedure is to insert it directly into the 2" eyepiece clamp of the APO.
