The MPCC Mark III had been designed for an f/ratio of f3.5 to f6. If it is used outside this range, slight losses (coma) in image quality at the edges of the image field can be expected. At f/7, you will hardly notice this.

Please advise as to whether this will work on a Celestron Omni XLT 120? Will it fit directly onto the bear focuser draw tube? I don't have the adapter/end cap that fits onto the end of the focuser tube.
The tube does not have an external thread nor an internal thread. I think that it uses a flange-like fitting.
If you have a model that will work, which one is it?
Depende de la distancia focal de su telescopio. Las Pléyades tienen una extensión de aproximadamente un grado en el cielo, lo que equivale aproximadamente al doble del tamaño de la Luna llena. El campo de visión del telescopio se puede calcular con la fórmula: Campo de visión ocular x distancia focal ocular / distancia focal telescopio. Con una distancia focal del telescopio de 1000 mm, el cálculo sería 72x36/1000 = 2,6 grados. Eso sería suficiente para obtener una vista completa de las Pléyades.
It depends on the focal length of your telescope. The Pleiades have an extent of about one degree in the sky, which is about twice the size of the full Moon. The field of view of the telescope can be calculated with the formula: Eyepiece field of view x eyepiece focal length / telescope focal length. With a telescope focal length of 1000 mm, the calculation would be 72x36/1000 = 2.6 degrees. That would be enough to get a complete view of the Pleiades.
