Io Transit to Jupiter (Oct 14, 2023) sent on October 17, 2023 (9:55) by Motofoto. 10 comments, 556 views.



Ottica C8 arancione del 1976 (mai ricollimato), barlow 2x celestron made in Japan dell'epoca per una focale di 4046mm a f/20. Montatura a forcella classica, con inseguimento solo AR. Guida "a occhio" con variatore di frequenza appena riparato dopo 20 anni di morte apparente. Ora l'inseguimento è stabile...come un ubriaco appena uscito dall'osteria. Fotocamera Canon 6d (ormai vintage pure quella). Di recente c'è solo lo stack software: EOS Camera movie record, pipp, astrotrakkert!, winjupos, wavesharp e photoshop. Ripresa in liveview a 5x,30fps: sette video di circa un minuto l'uno. L'immagine è un po' sottocampionata perchè i pixel della 6D sono troppo grandi per la barlow. La derotazione ha lavorato bene sul pianeta, ma ho dovuto disabilitarla su Io perchè mi lascia aloni che diventano problematici in post.

For me, the orange C8 is an excellent job,
that of advertising with Leonard Nimoy

I'm surprised by the result too, since it's the first attempt with a capture and post-production chain that I've never used before.
It must be admitted that, nowadays, the availability on the web of information relating to the configurations and operating procedures to be followed, and also the free programs to be used in post production, make everything easier than 50 years ago. Back then it was hard to know what to do without joining an amateur astronomers' club.
Books on the subject were also rare (Walter Ferreri's Astronomical Photography was published in 1977).
Not to mention post-production: the unsharp masks were made with negatives superimposed in the darkroom, other than AI, convolutions and bilateral filters at the touch of a mouse. 8-)

Chapeau for technique, execution and final result.
Now the chase is stable... like a drunk who has just come out of the tavern.
