Hello Excuse me for a while’ I did not hear but work commitments are deadly in this period. However, I am ready to return to work this weekend and I'd like to start with perfecting the image acquisition of the Ronchi and in this regard I really wanted to ask Stefanosky How do you create these images so sharp because in fact it is difficult to make a diagnosis when are so bad as my .
I tried some applications or rather I downloaded but now I have to test to see the result. I think it's important First solve this before entering into the debate on how to correct any defects in shape because at least so I can get a report of the process for future lenses.
However, the image I posted is obviously intrafocale
Kill what is complex…once before it was soo.
Anyway I hope you understand how it is put, the central hole is now more extended, but less deep than before; I should just work area 3/4 external, to remove the step before the border…
Well meanwhile Thank you all for your very warm welcome. I would like to be able to post some pictures I made of Ronchi but I do not know how to make a quality picture; I use a tablet 8 inch so it's not exactly the best as practical. Here on the site I can not find a button “attached” and then also the bad image that I made I can not post it and anyway I'd like to know how do you make those shots so clear your mirrors is also a great way to have a book with various jobs.
I did a little’ CoC alternating with mirror above and below but I think that goes with tool over slightly better.
It must be said that the disc is often 55 mm and with mirror above is a blow for how heavy.
Thanks for the tips I will try not to spill over the sidesWell yes we say that the gim’ s Mobile at the time was a great tool, Optically perhaps still is but we visualist we do not need so short because of focal undertake to greater obstruction of the secondary and then often the eye position is really uncomfortable, for this reason I had an old Marcon lens with an edge that most replied that I flat-spotted defined… I put it under the grains and 1500 I reported to the focalle 1700 with the classic mistake to stretch it a bit’ too much. Now we are in 1770 but fair enough and therefore are at an advanced stage and polishing with the usual mistakes I was doing well in his time… then I've got a slight central hole that however I am correcting with short COC movement then I'm looking for a moment to check the usual edge retorted that it is still very contained the most difficult part was to readjust the pitch which was obviously on the curvature of a ' other perspective that I made at the time so 1500 scarce and it took me a while’ time we say to mix it and adapt it to this 1770 so it took a little’ of time. Even for preparing the tool I used the tiles of stoneware with a simple cement glue Millechiodi support and which proved to be phenomenal
