Yes, the magnification is reduced by the same number printed on the reducer. In this case, it would be by .63 No Focal Reducer, a 25mm eyepiece = 2032mm/25mm = 81.28x With f/6.3 Reducer, the 25mm eyepiece = 1280mm/25mm = 51.2x If you divide 51.2x by .63 it equals 81.28x Therefore, whatever factor of focal length reduction is done by the focal reducer, the same is done to your eyepiece magnification.

Dear Cody, thank you very much for your videos! I've got really lot of useful information about astronomy in general and Celestron SE8 and different accessories for it in particular (I have Celestron C8-SCT, so it's pretty much the same). Can I ask your advice please? Regarding the brightness of picture and deepsky objects applicability: - In online shops & forums there are a lot of positive reviews about the applicability of f/6.3 reducer for visual observation of deepsky object - that it gets more visible, brighter etc.; - It is interesting to compare two options (for Celestron C8 SCT): - If I use the eyepiece [ES 82° 14mm without f/6.3 reducer] then I come to something like this: [145x magnification] / [0.56° FoV] / [1.40 mm exit pupil]; - If I use [ES 82° 8.8mm with f/6.3 reducer] then it should give pretty much the same: [146x magnification] / [0.56° FoV] / [1.40 mm exit pupil]; So the question is: - If I come to absolutely the same characteristics (magnification, FoV and exit pupil) in these two options - does it still make a difference in visual perception of deepsky objects? I.e. - will [145x / 0.56° / 1.40mm with f/6.3 reducer] give a nicer experience with deepsky objects than [145x / 0.56° / 1.40mm without f/6.3 reducer]? - PS: Of course, 145x is too high for many deepsky object - I used it just as an example, because the characteristics of [14mm without f/6.3] turned out to be absolutely the same as [8.8mm with f/6.3]. But the question is still valid in general: for any common [magnification / exit pupil] which can be reached both with and without f/6.3 reducer - does it make sense to use f/6.3 option to have a better experience with deepsky Best regards, V

Hey Simon, good vid, thanks! I do have a question though. I am new to this and so far I think I prefer a refractor for quality and viewing enjoyment. You said you like to keep the focal reducer on pretty much all the time on your SCT. I’m sort of understanding that to mean that your focal length of the SCT is too long for the type of viewing you enjoy. My thoughts for myself would be to buy a 120 mm refractor with an FL of about 850, and then use a 2x Barlow to get a longer (1650) focal length. Does this make sense to you? I’m really conflicted as to what kind of telescope I should buy…. 🤔😀 cheers!

Would a focal reducer be of use when looking at planets or the moon?
@Theothercrappyname4 жыл бұрын
Generally no, A focal reducer lowers the focal length or "Zooms out" in a sense, the faster f/ratio also providing faster exposure speed. This makes them suited for large widefield objects like Nebulae, or star clusters like the Pleiades. Astrophotographers use them for these wider sharper field of views, and that it allows shorter exposures. For Lunar+Planets you tend to want the opposite, you want a very long focal length to "Zoom in" as planets are tiny objects. That's either wanting a telescope with a long native focal length, the use of a Barlow to increase focal length, or a camera with a very narrow sensor. One example though I can think of where you would use one here is if you're into lunar photography and the native focal length of your telescope is long so that only a portion of the Moon is visible but you want to take photos of the whole moon. Often you would take photos of each visible portion of the Moon and stitch them together to make a higher-res image of the whole moon, but if you don't want to do this you could use a focal reducer to "zoom out" so that photos would show the full disc of the moon. If you were looking at the Moon visually, I'd recommend a wide eyepiece instead of a reducer.
