My little Vixen

[John]

During a cloudy patch earlier tonight I snapped a few pics of my Vixen ED102SS on the AZ-4 mount. You don't see many of these scopes around - they were produced in Japan around 10-12 years ago. The optics are an F/6.5 doublet with an ED element which is probably FPL-51 although Vixen didn't disclose the glass type used. I've owned this scope for quite a few years now and find it extremely versatile. With the 31mm Nagler in the diagonal the true field of view is around 3.8 degrees which is enough to fit the whole of the Veil Nebula complex in . At the other end of the scale tonight this scope was showing a clear split of Eta Orionis at 248x with the colour differences between the two stars nicely differentiated.

It's a really nice, portable, capable, hassle free scope

Great setup!

With the 31mm Nagler in the diagonal the true field of view is around 3.8 degrees. How to count this?

Thanks.

The 31mm Nagler with this scope gives a magnification of 21.4x. The apparent field of view of the Nagler 31mm is 82 degrees. To find the true field you divide 82 degrees by 21.4 which gives 3.83 = the true field in degrees.

That's a nice setup John - ideal, perhaps even essential given our climate!

A lovely scope John. Most of the ones you see are the f9 (920mm) versions.

I have to admit John, even though it's a frac, your scope's as lovely in the pics as it is in the flesh.

I appreciate that compliment Shane - thanks

Thanks Matt

You don't see many of the F/6.5's around.
