Special eyepieces (Guiding, Diascope etc.)

For visual use the ClickLock diagonal and the 2" SC ClickLock clamp is great. According astrophotography you need to go another way
because the telescope requires a dedicated back focus distance to the camera. Therefore Celestron is offering a special adapter #93644 which is made of two pieces. Without reducer at f/10 the back focus length is 133,35mm, with reducer at f/7 it is 105,0mm. At last you´ll need a matching T2-Adapter for Nikon. https://www.baader-planetarium.com/en/baader-t-ring-nikon-to-t-2.html
I know it is less convenient to change accessory but for astrofotography you have to spend more attention that you´ll be successfull.

Unfortunately this will not fit. The dovetail on the base of the finderscope has around 32mm width and will not fit in a 14mm clamp

Right now there are three different Hyperion Zoom eye pieces existing - the Zoom, the Zoom Mark III and Mark IV. The first generation has no
M43 thread but only SP54 so you don´t need this adapter. Thank you for the hint - we will change the description of this item.

Unfortunately it is impossible to reach focus with one of our bino viewers in a spotting scope, doesn´t matter wich spotting scope. The focus mechanism of any Spotting Scope is internal and therefore focus travel is too much limited to allow attaching a binocular viewer

For a 52mm lens, you need:
- Baader DSLR-2" Filter Holder M48/SP54 # 2408166
- Baader Hyperion DT-Ring SP54/M52 for DT-Adapter II&III and Hyperion Eyepieces # 2958052

You can screw all mounted 2"-filters into the filter holder which use the astronomical 2"-thread of aproximately M48x0.75 or M48x0.6 (we try to make our threads so that the common 2"-filters fit, although there is no real standard for this thread.)

Our filter-cells like # 2459252L are made for round filters with a diameter of 47,4mm and offer a free aperture of 46,9mm.
