Description

First LRGB test without RGB! :-D

Sky condition was very bad, strong haze, bright half moon and a strong light toward our observation field...
...as a result HUGE stars, low definition, strong noise in the background and RGB data was so bad to be unusable...
...but after a lot of rainy weeks even a bad shot is better then nothing and so here my very first test with my CCD and a luminance filter.

For sure not my best shot but I'm quite proud of it: it's mine first L ... (RGB)

Also visible the galaxy PGC25034 in the lower left corner and another small unknown (for me) galaxy near NGC 2685

Prima prova di LRGB senza RGB! :-D

Condizione del cielo veramente pessime, foschia, una luminosissima Luna al primo quarto e un faro puntato dritto verso il nostro campo d'osservazione ...
...risultato: Stelle ENORMI, bassa definizione, forte rumore sul fondo cielo e dati RGB talmente compromessi da essere inutilizzabili.
...ma dopo un sacco di settimane di pioggia, anche uno scatto pessimo è meglio di niente e così ecco il mio primo test col CCD e un filtro di luminanza.

Di sicuro non è il mio scatto migliore, ma ne sono abbastanza fiero: è il mio primo L ... (RGB)

Visibile anche la galassia PGC25034 in basso a sinistra e un altra galassietta sconosciuta (per me) vicino a NGC 2685
