Fluorite Flatfield Converter (FFC) / 3x-8x
In follow-up to my first question, please tell me the mechanical length of this device, really its optical length in mm from mating surface to mating surface excluding the protruding threads. The charts you mentioned do not provide this information, and I need to determine if there is sufficient backfocus distance on my optic to install it.
Answer rated: 1The mechanical length of the 2" plug-in sleeve is 55mm (measured from the ribbed stop ring down)Answer by: Baader Web Team (Admin) on Apr 13, 2021 12:43:00 PMRated: 1

Baader SC / HD Ultra Short T-Adaptor, 7mm optical length
I have Celestron Evolution 8 EdgeHD scope with a 2" SCT thread on the rear cell. I am struggling to find the correct model diagonal for that rig, can you please provide additional information? I read the primer helpfully provided, but there are two options that are both recommended, the SCT-Clicklock visual back + the clicklock diagonal CLDIAG-2, and the same diagonal but this time mounted somehow flush on rear cell. Which is actually better? The eyepiece I was most is my Mark IV 8-24mm Zoom w/Barlow combo, if that matters.
Answer rated: 0The ideal backfocus of the Edge HD 8 telescope is 133,35mm behind the 2" thread on the rear end. The closer you come with the eyepiece field stop to this point, the better is the star image on the edges of the field. The mirror has 112m optical length. The ClickLock 2" clamp for the rear end of the telescope has 47mm optical length. Means either way works similar good, you are always a little more tahn 20mm from the ideal focus point, wich is not an issue for visual observation with this telescope, especially not when observing with high magnification. When attaching a camera, you will need to take care that you are exactly in the right distance with the CCD sensor, as described in the manual of the telescope.Answer by: Baader Web Team (Admin) on Apr 13, 2021 9:15:00 AMRated: -1

Diamond Steeltrack® T-2 Adapter
Can i use this with a coma corrector threaded to the telescope side?
Answer rated: 0Unfortunately we don´t know a combination with a coma corrector that will fit. Coma Correctors like our MPCC have 2" barrel to come in the right place in the optical path. And they provide a different thread on the camera side that is not fitting to this adaptorAnswer by: Baader Web Team (Admin) on Apr 13, 2021 8:16:00 AMRated: 0

Steeldrive II motor focuser with Controller
Great product! Is it possible to control the motor directly from an astrophotography software on the PC using the RJ-45 connector and an Ethernet cable (PC => Ethernet => motor), without going though the controller (PC => USB => controller => Ethernet => motor)?
Answer rated: 0Thank you! Unfortunately you cannot connect the motor directly to a PC program, you always need to go through the SteelDrive controllerAnswer by: Baader Web Team (Admin) on Apr 13, 2021 8:20:00 AMRated: 0

2"a / T-2i Zero-length reducing piece (zero optical length)
May I use the 2"a / T-2i reducing piece to connect a 2" / 90° Astro Amici-Prism diagonal in a T2 quick changer system?
Answer rated: 1Even if it mechanically is possible, it will have one big disadvantage: T-2 has 42mm aperture, 2" Is 50mm. Means, you step down the aperture of the prism so that you will experience a vignetted field when viewing with long focal length eyepiecesAnswer by: Baader Web Team (Admin) on Apr 8, 2021 9:18:00 AM
