Ho questi pezzi da un po', prima o poi mi ci metterò, anche se non ho tutte le competenze necessarie.

In the web there are several aid, you have to have the desire and time.

A dire la verità hai commentato l'unica foto che illustra un lavoro morto lì; il motivo è che ho acquistato una slitta Wemacro motorizzata. Non ho le tue competenze ( ho scaricato i tuoi programmi e le tue tabelle) purtroppo, e per gli sketch di Arduino mi devo affidare a quello che trovo in rete. Non è detto però che prima o poi non termini anche questo progetto, benché sia pesante e che poi non saprei dove metterlo. Ho (abbiamo, ho un "amico di stacking") ammirato i tuoi lavori sin dagli inizi del mio interesse per questa tecnica, quando cercavo in rete esempi ed informazioni.
Per me il divertimento è anche costruire i "banchi" per la macrofotografia e quelli che ho li considero molto versatili, quindi l'attrezzatura ce l'ho, se non faccio belle foto è perchè proprio non sono capaceSorriso.
Grazie dei complimenti, ma se hai critiche e suggerimenti sono bene accetti.

Luciano

We probably have the same disease ... photography is only a means to pursue other interests :)
But seeing that beautiful Del-Tron abandoned hurts the heart ... if you want to finish it I'll send you a card to be inserted on Arduino, scketch and management program (only runs on Win), and in five minutes you're done.
And 'the system that I use ... in addition to the motor control calculates the optimal length of the steps depending on the operating parameters, operates two light channels is adjustable so continuous illumination is im impulsive type flash, the shutter control in the channel IR.

Hi, I post I even I in conversation. The Andrea card and 'a panacea to power the desk. No frills but with all that you need. It is constructed with little expense and the result 'of course. Of course not 'and' all resolved, but at least a good part of it. Since using it I had the chance 'to concentrate on other aspects (lights, position of the subject, post production etc. etc.) even if the road and' still long. Personally I use two Del-Tron I find them much better than other much more 'noble and expensive sleds.
Hello walter

Andrea, thanks to supply and accept it although I have not Windows, or I through Parallels on the Mac.
Me it would take two cards, one for my friend already mentioned, it has a lot of equipment like mine, including the Del-Tron (and also the slide Wemacro). I thought I was doing a stand alone system without connections to the computer, but having already Wemacro which in theory can bring to the field, it's OK to me a fixed system in "study".
If you communicate to me in MP all the details (costs to be paid, information etc) you agree to ship.
Thank you, you're so kind.

Thank Luciano for giving me involved in this thread - I introduce myself: I am the friend of stacking mentioned Luciano - and I'd be very interested in developing the Del-Tron. So thank you from now Andrea (which is true, I really enjoyed the photos, and I thought more than once about a Mitutoyo that I bought used and that gives me good pictures, to ask him for advice on possible investigations ... and interventions) if you would help us.

Hi Nicola,
Mitutoyo for the causes can be many ... some others are not solvable :-( if those linked to the use / tube lens and so on. There are no problems, but reading on various forums some 10x at some point no longer go well and the mitutoyo said that no repairs ... so if you have been unlucky enough to run into one of these there is nothing to do.
Let me however to know what kind of goal is that the tube lens use, and step length do during the stack, also a crop at 100% would be helpful to see it.
For Del-Tron I have a friend who drives a (Nema 23) with my card and it works well, but also for you that is what I said to Luciano ... check before if the program runs on your machine then I can send you a card to be inserted on arduino (though it is one of the prime I did and did not have the light control and IR remote shooting)

Ciao Andrea, grazie per la tempestiva risposta. Purtroppo credo che il mio Mitutoyo 10x sia uno di quelli per cui non c'è niente da fare .. L'ho comprato usato su ebay e forse chi me l'ha venduto se n'è voluto disfare, o forse il danno è avvenuto durante la spedizione; la scritta sul contenitore "do not fall or drop, the performance may deteriorate" mi dà da pensare, forse il pacchetto è caduto o è stato un po' troppo sballottato ..
Comunque: per il Mitu 10x utilizzo dei tubi di prolunga con lente Raynox 150 macro, circa 20 cm di lunghezza, calcolata per mettere il Raynox a fuoco all'infinito. Al termine del tubo, fra il Raynox e il Mitutoyo (che si trova a circa 4cm di distanza) ho messo un diaframma che chiudo un po' per limitare i riflessi. La fotocamera è una Sony nex a6000 (24 megapixel su sensore APS-C) ..
Con lo stesso sistema utilizzo anche un Mitu 5x, ottenendo buoni risultati. Lo step che utilizzo col Mitu 10x è di 4-5 micron. Per la somma delle immagini uso sia Zerene sia Affinity photo, non ci sono grandi differenze nei risultati. Il peggior difetto delle foto, oltre ad una definizione non eccelsa, è un effetto di 'abbagliamento' dei punti più luminosi ..
Ti invierei una foto per chiarire meglio quello che intendo, come mi consigli di fare? (non sono esperto di forum e praticamente non ho mai postato foto finora!). Grazie ancora per i consigli che vorrai darmi, a presto

Quindi dobbiamo escludere l'attrezzatura che è tutta OK .... la lunghezza di step è anche troppo corta ... io a 10x utilizzo 7.5 e qualche volta anche 10 micron ..... quindi escludiamo anche quella.
Anche per la distanza lente di tubo sensore non ci dovrebbero esser problemi Mitu è un'ottica abbastanza tollerante ... io per trovare la distanza corretta più che al calcolo ricorro agli occhi Sorriso ovvero metto a fuoco un punto all'infinito solo con la lente di tubo ma ho visto che pur allontanandosi sensibilmente da questo valore ottimale non si hanno sensibili degradi.
L'algoritmo di fusione piramidale PMax di Zerene e C di Helicon tendono ad esaltare effetti d'abbagliamento intorno ai punti molto luminosi in particolar modo su sfondi scuri ... DMap e B da questo punto di vista son ben più tolleranti .... per eliminare questi problemi, sempre che la causa non sia l'obbiettivo, occorre diffondere la luce e in queste foto il diffusore è tutto .... cosa utilizzi come diffusore e luci?
Chiudere il diaframma equivale a perdere in risoluzione e va usato con molta parsimonia diciamo meglio non toccarlo ... potresti ottenere migliori risultati da crop in 5x.
Per la foto la via più semplice è d'inviarmela per e-mail ti mando le mie coordinate per MP

Oh yeah I forgot lighting: use the flash Canon Macro Twin Lite MT-24 manually with speakers (dedicated) further attenuated with white paper inside. actually I could put an additional speaker (white plastic) between the flash and the subject ..
Thanks for now, try a couple of significant crop 100% tonight and you send them ..
