Precise spacing of 383L+ , is it 17 or 17.5mm?
« on: November 25, 2012, 10:19:33 pm »
Hello everybody.
Just few weeks ago I purchased second hand atik 383lc+ to use in my newton N6 and triplet 90/600. I used to read this forum since August but this time I would like to ask for little knowledge.
For N6 I have baader's coma corrector mpcc that requires 55mm distance to chip and for triplet I have two FF/FR with different backfocuses (56 and 118).
I am to order dedicated T2 extenders, and I am a very precise man. For 383l+ the chip distance I found a value of 17.5mm in mechanical drawing and value "approx. 17mm" in manual.
Anyone can tell me exactly the chip spacing? Please let me know which value is correct (17.5 vs 17 vs other) so I can precisely design extenders.
Regards,
Pawel.
