Re: Vixen ED81S f/8
The finderscope can be illuminated if required for centering a object if you require.
The flip mirror is not great but when imaging you do not use a diagonal anyways so you can use it visually.

I found 1 reducer. Not sure if it flattens too. I'm hoping I can find a 1.0 flattener so I can use maximum focal length. Any idea if there is 1?

A flattener barely changes the focal length, really a unneeded item.
You can purchase flatteners, reducers, extenders, flat/ reduce combo.
The lowest weight is just the bare tube with no accessories at all.

Re: Vixen ED81S f/8
So if i want to image at the longest focal length, i only need a flattener, right? If i want to shoot at a reduced focal, I need both a flattener and reducer? I thought the reducer also flattened, but I guess not unless I find a special combo item.Lady Fraktor wrote: ↑Sun Nov 13, 2022 4:50 amThe Vixen part numbers should be in the manual, Explore Scientific is the USA distributor now so you should find the items on their website.hatflyer wrote: ↑Sun Nov 13, 2022 12:22 amDo u know what components go between the scope and myLady Fraktor wrote: ↑Sat Nov 12, 2022 5:24 pm The focuser is a good rack & pinion, dual speed is a add on option.

So, I guess I need a 1.0 flattener when I don't want to reduce, and also a reducer/flattener combo to increase the speed? 2 items, but only 1 is ever used at a time on the scope.
What parameter should I look for in terms of connectivity to this scope if I use a cheaper version of reducer and flattener? Is it a diameter, thread, focal ratio? Not clear from the manual.

Re: Vixen ED81S f/8
The manual gives you the part numbers so you can look them up on the Vixen Japan website.
All the thread sizes and such will be listed with the part.
I have no ideas about substituting parts. I am sure you can, just match threads and sizes.

Re: Vixen ED81S f/8
If so is it a ED or SD? There may be differences, you will have to find out.
The Teleskop-Service one says for ED, the full kit I gave a link to is for SD.
Email TS and ask if it will work for which ever version you are getting.
If it will work you will still need spacers, extensions and camera to focuser adapters.

I emailed TS.
It's the ED.
Is this all I need?
Vixen Reducer & Flattener 0.67x for ED
TS-Optics Optics T2 Adaptor for NIKON Cameras
Vixen adapter from M60 to T2
The manual diagram isn't clear on whether the tube and spacer ring are needed if using a combo reducer/flattener.
Actually, with this scope and dedicated reducer do I even need a flattener? Or when shooting at 625mm?
Thanks.

Re: Vixen ED81S f/8
I'm getting just the field flattener/reducer combo (almost cheaper than a flattener alone) as I know I want a reducer, then I'll see if i need a flattener alone for 625mm shooting. Seems maybe I won't need a flattener, depending on whom I ask. Not getting the whole $500 kit from Vixen.JayTee wrote: ↑Mon Nov 14, 2022 7:25 pm My approach is the slow approach. I could never get enough info on the proper gear from the git-go, so I bought my ES 80mm APO with no extra gear. My thoughts were that if the FOV shows pinpoint stars all the way to the edge then I don't need a flattener. If they aren't then I go ahead and purchase an appropriate flattener. Next, do I really need a reducer? I look at the FOV of OTA vs the objects I want to image. If they don't fit, then a reducer is needed. I never buy just a reducer, it is always an FR/FF. I never want more pieces of glass in the optical train than are needed.
