Ho sempre molti dubbi sul come deve essere l’istogramma corretto, in ASIAIR …
Sapete darmi qualche indicazione in più, per un istogramma corretto?

1. Non c'e' *un* instogramma corretto. L'unica accortezza e' di non saturare (troppo) le ste;;e piu' brillanti.

2. Stai raffreddanto troppo la camera, ci sono tracce di condensa sul sensore.

3. Nelle tue condizioni un filtro di soppressione dell'inquibamento luminoso o meglio ancora a banda stretta e' assolutamente necessario.

Che occhio clinico🙂… ho usato una foto in un certo senso a caso, solo per un esempio di istogramma.. mi avevi forse ancora tu spiegato il problema della condensa/ghiaccio per la temperatura esterna piuttosto alta (sopra i 20C impostare al max 0 C)… 
Cosa intendi in pratica, cercare di non saturare troppo le stelle più luminose? come capirlo..( quanto ho ancora da imparare).
Sto usando già un filtro antinquinamento luminoso.. Antlia Quad band.. con bortle 7/8..
e un bibanda 7 nm H-alpha OIII per varie nebulose..

Guarda a destra nell'istogramma e se c'e' poco o niente sei a posto.
