Widescan 111 16mm 84DFOV

[astronut]

I have for sale a eyepiece made by Kokusai Kohki in Japan and sold in Australia as a Widescan 111, it's a 16mm 84DFOV. 1.25" barrel.
I've had this e/p for about 10 months.
It comes in as new condition with both end caps + eyecup and original box, also in as new condition.
This e/p gives great contrasty views and in a scope of F8 or slower does not show any field distortion.
In a faster scope it is a little more noticeable, but not annoyingly so.
The views are wow!!!!!! there's no other way to describe it.
The reason for the sale is that I've found that it only just comes to focus in my LB 12" and I run out of inward focus with a barlow.
For a slower reflector or a refractor or a Schmidt - Cassegrain or similar slower F/ratios, it would work very well.
New price $ 299
My Price $210 including postage within Australia

Hi,
I'm keen but, I would probably encounter the same focus problems in my f5 12" GSO dob perhaps??????
Cheers

Unfortunately yes, Doug:sadeyes:

Was it only in the barlow that you couldn't reach focus?

Was this dependant on the type of barlow - or is that wishfull thinking?

Cheers

I imagine it would depend on the type of focuser and how high/low profile it is, too?

Doug, It will reach focus on the crayford focuser on the LB. The barlow is a Meade shorty type, so the eyepiece is not disadvantaged by this.
I've taken the 1.25" adapter out and held the e/p barlow in the light path, it would only have to drop another 10mm and it would reach focus:doh:
