Not bad. Too bad for the excessive exposure that emphasizes the fringe and penalizes the overall contrast. Still a good result. What optics were you using? Non male. Peccato per l'eccessiva esposizione che enfatizza il fringe e penalizza il contrasto generale. Comunque un buon risultato. Che ottiche stavi utilizzando?

@AstroC I did with the smartphone's night mode and it was a point-and-shoot. It's certainly not a professional image, but in a discussion we were talking about smartphones and I uploaded it to share it. To your question I will answer: I photographed with a smartphone resting on the eyepiece (if I remember correctly a 14mm) mounted on an 8-inch by 1200mm Dobsonian telescope @AstroC ho fatto con la modalità notturna dello smartphone ed è stato un punta e scatta. Non è di certo un immagine professionale, ma in una discussione si parlava di smartphone e l'ho caricata per condividerla. Alla tua domanda quindi rispondo: Ho fotografato con uno smartphone appoggiato all'oculare (se ricordo bene un 14mm) montato su un telescopio dobson da 8 pollici per 1200mm

By using it in projection from an eyepiece, you simply took advantage of its sensor. Doing it freehand penalizes the result because of the inevitable move. On the market they sell special supports to be applied to the eyepiece, making it much more stable and obtaining images on a par with those obtained by any camera, net of the optics used. It's a good helper and a starting point for good photos. In this case, the resolution of the dobsonian is in sight. You can clearly make out the outline of the Rupes Recta. For shots of the Moon, however, I would have avoided the night mode. The light on an 8 inch should be more than enough. Less overexposure and less fringe on the edge. Utilizzandolo in proiezione da un oculare hai semplicemente sfruttato il suo sensore. Farlo a mano libera penalizza il risultato per via dell'inevitabile mosso. In commercio vendono appositi supporti da applicare all'oculare rendendolo molto più stabile ed ottenendo immagini al pari di quelle ottenute da una qualsiasi fotocamera al netto dell'ottica utilizzata. È un buon aiuto ed un punto di partenza per buone foto. In questo caso la risoluzione del dobson si intravede. Si riesce a distinguere chiaramente il profilo della Rupes Recta. Per scatti alla Luna avrei però evitato la modalità notturna. La luce su un 8 pollici dovrebbe essere più che sufficiente. Meno sovraesposizione e meno fringe sul bordo.

Thanks for the advice! I've seen the supports, but so far I haven't taken them because I don't have a tracker, so I could take shots with fast times and with magnification factors that are not too high. Basically, I imagine not much better than what I get now by putting the smartphone on the eyepiece. But having little experience in this regard, maybe I'm wrong Grazie dei consigli! I supporti li ho visti, ma finora non li ho presi perché non avendo inseguitore, potrei fare scatti con tempi rapidi e con fattori di ingrandimento non troppo spinti. In sostanza immagino non molto migliori di quello che ottengo adesso appoggiando lo smatphone al l'oculare. Ma avendo poca esperienza in merito magari sbaglio

The lack of tracking unfortunately limits a lot on all fronts. Even in visual observation only. It tends to make everything a little less relaxing. I hope you will soon make up for this lack so that you can take full advantage of the optics even at high magnifications. La mancanza di inseguimento purtroppo limita molto su tutti i fronti. Anche nella sola osservazione visuale. Tende a rendere tutto un po' meno rilassante. Spero ovvierai presto a tale mancanza così da poter sfruttare a pieno l'ottica anche a ingrandimenti sostenuti.
