A suggestion for Iceman's planetary eyepiece

Hi Ice,

Woke up this morning before the kids and was thinking about space stuff of course. I thought about how much i am using asimov's 5mm vixen.

Like using it every night!!!.

I have had terrible seeing, yes, but even 12mm would be no use!. So it is not thaht the seeing has been perfect cos it hasn't!

I would honestly recommend / suggest getting a 3mm, 4mm, 5mm, 6mm & 7mm vixen lv on loan and take them to lokstock. Write up a review on what you think.

If i go the vixen (and at this stage i will) , i will buy a 4mm & a 5mm , no questions about it.


I simply use the 5mm every time i am out there!! I would be seeing detail on mars (it will still benefit with from an ir/uv filter) 8 out of 10 times with the 5mm!

I would hate to see you get the 7mm and then find you could of gone a 5 for most times and a 3 or 4mm for special seeing times???

Just trying to work out what magnification that equates to, your F/L is about 1250mm I think, that would make the mag with a 5mm at 250x, that's equivalent to 8mm on my LX. I wonder how the Vixen's go on SCT's...

Phil,

The Vixen LV's are a fine planetary eyepiece, infinitely superior to anything made in the far east but very marginally behind a good ortho or top grade plossl. Just as sharp on axis but slightly down on light transmission IMO by about 5%. This however, is something that takes an experienced observer to detect and to a lot of people the difference would be undetectable. Considering they preserve the 20mm of eye-relief in all focal lengths they are very hard to beat. AFOV is narrow compared to the premium widefields and similar to an ortho, however on a tracking scope as a planetary eyepiece I don't see that as an issue in any way.

Highly recommended at the current selling price of about <$A170.
