Wow! A 6mm plossl with 17mm eye-relief for only $30?

Ian,
I just PM you to place reservation for item 3 (Skywatcher Ultrawide 15mm ; AFOV 66deg ; Eye relief 13mm).

BTW, here is a link to the Sky-Watcher UltraWide eps specs...

Hi, Alvin,
Will reserve the item for you, in fact I got two pcs. The other one still up for sale if anyone else keen.
And thanks for the link

Cheers

I don't believe the eye relief if 17mm :?: (more towards 7mm maybe) I got that from a website, in order not to mislead anyone I edited that in the original post.

Cheers

I think the eye relief would be more like 5mm. Plossls eye relief is about 80 percent to its focal length.

Hi Ian,
For item 2 (Skywatcher Ultrawide 6mm ; AFOV 66deg ; Eye relief 13mm), do you also have a matching pair? If you have, I'll add that to the single 15mm UW ep I intend to buy from you. Read my reply PM for more details. Thanks!

PS:
Ian just replied through PM that he has only one pc of all other ep. Anyone else has the same ep (Skywatcher Ultrawide 6mm ; AFOV 66deg ; Eye relief 13mm)? I will combine the purchases IF there is a same ep around for sale.

Upzz, still have some cheap and nice ep to sell (see original post)
The skywatcher ultrawide series is equivalent to the orion expanse wide field series.

Cheers
