Here I am again operating! I had a busy schedule but now I can go back to devote myself to the telescope (I want to finish by summer).
I am therefore left with the spherical mirror and an unreliable foucault tester. The pitch tool is stopped by 3 month or so but being the rather cold temperatures it is kept intact at the sight. In addition of course to wash, keep it in hot water and ripressare several times to get him back on the right impression, recommended brushing the surface or have other expedients?hello Luigi, I too welcome! And good luck to your glass, a very similar job to my 300/1800. I'm trying to set up a foucault tester that allows me precise and repeatable measurements, then I will finish the parabolizzazione. I've been a little busy the last few weeks but I should get back to work shortly
ops! Sorry, I looked everywhere except in the download section!
However it could work my setup, I think the main problem is to place it on a nice smooth and stable base. I have to find a way to make a mirror port that allows me to place it at the meter level with different settingsThis is why it did not work Ronwin2.0! Figurexp I torvato and installed but I can not find a working link to Foucault Test Analysis.
However before you use one or the other must necessarily have a reliable setup that currently do not believe I have for different reasons. My 3D printed project is too small, lightweight saw the plastic material used and this does not allow me to maintain constant image.
Prior to meddle in the mirror I need to put together a setup that gives me confidence in what I do. Well, for peace of mind, however I will still have two or three rounds of the table with 1 / 3D. Now I need you…
Partirò with the races W Mot and will use only the Ronchi until reaching a conical around -0,5 Also insert after which Foucault. I am using RonchiZ as software because the others I've tried I do not work on windows 10, This, however, does not allow me to do many things, even to save a reference image.
For Foucault frankly I'm a little troubled. I still do not understand what software to use Agree (I see that many such use FigureXP while here using an excel file) also my setup as well as being a little too “leggerino” Apparently not allow me to create decent images and then I'm afraid I'll have to redesign one. in conclusion, I do not know if you realized but despite having read the guide Giulio'm Foucault continues to scare me quite a while
It seems to go a little better. However, when I approach very fire you are always sees a deformation of the line near the outer band, sign that we have not yet. Tomorrow reopen the tool channels because now begins to do a bit of aquaplaning and I will try to work a little bit more long-Tot. Hopefully sooner or later the ball is partorirla!
And this should be the easiest thing. If I think of what it will take me after pulling out a decent dish comes already anxiety
I said that badly, I did not mean an overcorrection of the real center, I meant that the two lines at the edge seemed more open me the previous Ronchi but this may also be due to the fact that most are placed externally, therefore closer to the edge, compared to the previous.
Thanks Giulio! Massimo apology but I thought long past Tot worked over the central area while the court Tot worked over the edge. Vice Versa Against, Court worked downtown and also worked long edge. However, I tried about twenty minutes Tot 1 / 2D but it seemed tended to sovracorreggere downtown and stopped.
I will try with past W Tot, specifically those:
UNDER MIRROR:
W passed to apply this "modified" in the mirror mode under, It will allow us to act more effectively on the circular mirror outer ring, It may be useful in cases where it is progressing in parabolizzazione, but the edge of the mirror tends to remain spherical, or if you want to attack a raised edge without, however, excessively modify the surface of the parabolic trend.
I alternated and Tot Mot 1 / 3D to try to even out a little bit areas, after which I worked a little Mot 1 / 2D to break down the edge but it was not enough. Then I tried to work with Tot past court, 1/4D about but the “Turned up edge” I will not let go. Tips?
Thanks Massimo, I suspected it was the most suitable choice. I will work to improve the figure and connect areas in the hope that the quality of my network allow me to distinguish any small errors.
I will proceed further by working past the board with 1 / 2D and Mot, once you reached the goal, I will try to standardize the ball with the classic 1 / 3D and alternating Tot Mot. At work!
More or less I should therefore be asking, it is essential to search for the absolute perfection of the sphere or this may already be an acceptable figure on which to work?I did not refresh the page, and your post I had escaped Giulio. Now I do a nice studied what you put! Thank you
I would say the second option is functioning properly, if everything goes the right way tomorrow, with a 20 minutes of work should finally get a good ball and be able to start with parabolizzazione
More than anything I'm happy because I finally started to understand how to behave glasses with various types of processing, I began to realize pitch, the pressures etc.… the step of polishing is decidedly less intuitive of the previous phases but by beautiful satisfactions. I still miss the most critical phase but positive!We assess the situation:
At this point it should fail again shortly to the ball. I am undecided whether to continue with Mot and spend 1 / 2D or Tot and spend 1 / 3D or shorter. The first should expand the processing center bringing it towards the edges, but my fear is that it is not sufficient to pave the raised edge. The second theoretically should work more on the outer edge, especially with past rather short. I almost feel Mot 1 / 2D, you who say?
Edit: You think, the edge is more raised than before or the optical effect is given by the fact that the lines are straight now to a larger diameter, and then the final curve is sharper?
