Hi Mogi,with subsequent correction strategies. with subsequent correction strategies, with subsequent correction strategies, with subsequent correction strategies. with subsequent correction strategies, with subsequent correction strategies, with subsequent correction strategies……. with subsequent correction strategies, with subsequent correction strategies, with subsequent correction strategies, for some, a goal that is difficult to reach, for some, a goal that is difficult to reach, for some, a goal that is difficult to reach. All that said, : for some, a goal that is difficult to reach……. for some, a goal that is difficult to reach. See you soon
I would say to keep it in evidence, if you can then create subtitles that would be a great thing!
It is precisely Dobson's approach and the level with which he presents the work that makes self-construction absolutely attractive to beginners. And this, as we have already shared, it is a fundamental element for us.
Welcome Massimo,
Ti ringrazio anticipatamente per il contributo che saprai dare al blog. Qui stiamo cercando tutti di dare il proprio piccolo o grande contributo per costruire uno spazio di condivisione di una particolare passione. Penso che ciò che ci accomuna tutti sia soprattutto il desiderio di far trovare ad un astrofilo italiano che si affaccia su questo mondo ciò che noi tutti non abbiamo trovato: una banca informazioni su ciò che occorre per costruirsi la propria ottica ed il proprio dobson.
Ti invidio anch’io……stasera “azzardo” una serata all’osservatorio di Novezzina che organizza la “occhi su Saturno”. Giusto perchè mi porto dietro mio fratello che non ha mai visto l’osservatorio e perchè, mal che vada, c’è comunque una conferenzina, a bit’ di gente con cui fare due chiacchere e, se il meteo costringe a tenere chiuse le cupole, un bel giro nell’osservatorio con aggiornamento sulle attività di ricerca.
Hello and welcome Emiliano between scratchers!
You were probably abundant in the request for carborundum……A little bad: the limit you will remain for the Toggle Next Mirror
If you are looking glass 20mm, making a round of phone calls between the glassworks in your area we will definitely find.
Of course, remember to point out that should NOT be tempered glass, possibly, made cutting discs from a plate not too young.
We have published some articles in the workplace: if you have not already done, I invite you to read them. If you do not have much time and you already know that appoint it several months, Do not underestimate the location you choose, to be at your disposal.
For the first phases of the work, Here you can find all the tips to start off on the right foot.
My advice in general at work are those already mentioned here and there:
1) if you're too tired, not to work on the mirror;
2) if you hurry, not to work on the mirror;
3) If you can not wait to indulge in the mirror and you have fun to scratch, what is a good time to scratch.
good job! My best wishes go to everyone, but especially to us, that we hope to accompany as many people as possible towards this strange passion.
I have a very ambitious goal in mind for 2015……but I'm keeping it for New Year's greetings…… hello Henry, welcome
In addition to what you advised Massimo, If I were you I'd do it a thorough cleaning of the workplace. In particular, if the lines are always the same size: maybe you have traces of larger grains in the workplace, the sponge you use to clean, etc
ps: I also left too early in the chordal and now I find myself a f6 (and certainly I will not go focal with finer grits….)hello Maurizio.
What test did you use to measure the focal?
Surely it is still better to wet the mirror to the measures.Hello Astrotechnician: Hello Astrotechnician
Hello Astrotechnician: Hello Astrotechnician, Hello Astrotechnician (Hello Astrotechnician……). Hello Astrotechnician?
Hello Astrotechnician……
Good job, Mirco, thank you!
I do not know if I would be able to build a similar machine…….But if I could build at least one electric rotating floor, therefore without arm, I could do all the processing phases, from roughing to parabolizzazione?
hello Maurizio, bentrovato!
If indeed you have not already worked a lot with 120, I counsel you to return to the chordal, possibly with 80. I left the chordal and 80 until 3 mm arrow and I can guarantee that, with the 1/3 COC without variants, It goes down very, very slowly. I think you can safely stop work with chordal a couple of tenths from the final arrow, the limit you can always put a mirror under.
