Hey guys! Very nice to meet you all - and of course to see U995 again I was especially happy to see the attention the HMS Marulken devs paid to everything! Oscar (Oskar?) asked in-depth questions and clearly had the drive to truly understand things, the kind of drive I see in the best technical oriented game designers! I think the future is bright

I'll post my pics too in a while, though this time I was not really shooting much and I was careless with the pics

Regarding the periscope question, I found something interesting in the British "Report on HMS Graph" (captured U570) - http://www.uboatarchive.net/U-570/U-...tishReport.htm - page 32

Zeiss Periscope No. 2523 (Watchkeeping Periscope)

Optical Data

Optical length 7 m. 55.

Main eyepiece:
Magnifications 6.1 and 1.54.
Angular field
High power
7° 15' vertical.
8° 46' horizontal.
Low power
29° 2' vertical.
36° 38' horizontal.
Exit pupil 7.0 mms.
Eye clearance 1.5 in.

Second eyepiece:
Angular field
High power 7° 3' circular.
Low power 28° 36' circular.
Eye clearance 0/75"
Elevation movement to 90°
Depression movement to 10°

So, as far as I read, one of the eyepieces presents a round image that can be raised up/down to check the sky, and the other one presents a ellipsoid image that is fixed?!

I haven't looked closely but think this might be of interest: http://www.uboatarchive.net/U-570/U-570Plate27.htm
