Pentax SMC XW10mm vs TV Delos 10mm

Hi All,

Received my First Pentax Eyepiece Yesterday a SMC XW 10mm, (fok4tel ), for a second hand unit it appears to be in Pristine Showroom Condition.

Assuming clear skies and no other interruptions I plan to do a direct comparison of this against my TV Delos 10mm which should arrive tomorrow afternoon.

Some first points to note for the Pentax is:

The packing and supplied documentation is very good.

The Pentax comes with a Bolt Case and 2 foam inserts in the case to protect the EP. It has good Top and Bottom end caps.

The supplied documentation clearly describes all the physical construction parameters of the EP such as:
  • Weight 405g
  • Lens Construction 7 elements in 6 groups
  • AFOV 70deg
  • ER 20mm
  • JIS Class 4 Waterproof
  • Exact dimensions
Overall the Pentax appears to be extremely well constructed similar to what I would expect from Takahashi or other professional Astro Company.

I was very surprised by the inbuilt EP Height Adjustment. Simply twisting the top part of the Eye Cap makes fine adjustment in height of the EP/Cap. First thoughts are that this is very nice but I will reserve judgment for how it works out practically.

Keep an eye out for the direct comparison which I will add to this post as it moves ahead.
