WOW! congratulations, you have to have closed all the stars so beautiful? if you kicked the ISO to 3200 had definitely more noise, but maybe it was not so useful because you can see really well! The reflector is a great "means" sin clutter is not always easy! the mount of respect and envy! You also took the trail of a meteor on the left, that great! WOW !! complimenti, hai chiuso tutto per avere le stelle così belle ? se alzavi gli ISO a 3200 avevi sicuramente più rumore, ma forse non era utile perchè così si vede davvero bene !! Il Riflettore è un gran bel "mezzo" peccato per l'ingombro non sempre comodo !! la montatura di tutto rispetto e invidia !! hai preso anche la scia di una meteora a sx, che grande !!

Thanks for all the comments! And sorry for the delay for the answer! There is reason Astro_kiara is a spike of mars. It can not be a meteor because it is present in all the 5 photos I took. @ Matte: the reflector is a beautiful instrument, collects lots of light. Unfortunately also suffers from flexing, which is added to the defects footprint. Anyway I really like this tool. Is giving me a lot of satisfaction. Use 800ISO is a great compressed between signal and noise in long exposures with canon in astrophotography. Raise more (at least with my 450D) is not recommended. The focal ratio of this tool is F5. Spikes are natural to bright objects. Grazie a tutti dei commenti!! E scusate il ritardo per la risposta!! Si ha ragione Astro_kiara, è uno spike di marte. Non può essere una meteora perchè è presente in tutti e 5 le foto che ho fatto. @ Matte: il riflettore è un bellissimo strumento, raccoglie tantissima luce. Purtroppo soffre anche di flessioni, il che si aggiunge ai difetti dell'ingombro. Ad ogni modo mi piace un sacco questo strumento. Mi sta dando tante soddisfazioni. Usare 800ISO è un ottimo compresso fra segnale e rumore con la canon nelle lunghe esposizioni in astrofotografia. Alzare di più ( almeno con la mia 450D) non è consigliabile. Il rapporto focale di questo strumento è F5. Gli spike sono naturali per oggetti particolarmente luminosi.
