Pelican Nebula … and North America Nebula

1/3 : Back to Sardegna. Last year, I got one shot (Helix Nebula) and I stopped everything after it : humidity was reaching 90% and my setup was sweating. I said in a previous post that the island is tough, some year it’s dry, some year is humid … I got the dry weather this time. I spent five nights, shooting from 10PM to 3AM (there wasn’t even dew … incredible) letting the setup outside until the morning without any anti-dew equipment (dry, dry, dry … perfect !)

Heart Nebula. Preview

I got a new setup. I promised to one of my colleagues a gift for her new achievement in life and that would be the Heart Nebula (IC 1805). I checked all configurations with Stellarium and N.I.N.A., but I knew that the Tak Mewlon and the C9 will not be able to get the full frame. I thought I got a chance with the Hyperstar on the C9, but I would have needed a bigger camera sensor (or using the APN, but as this nebula is so faint, I forgot about it)

Laguna Nebula, second try.

I got the reducer 0,67 attached, the ZWO 183MC Pro … and I was wondering if I got the right object. Clearly, the reducer helped to get a lot of light, faster a bit, but the colors felt wrong … the core is full of details, so I was okay about this at least. It was about 40 shots of 20s, camera cooled at 10 degrees C, and I made an effort to get flats/darks and biases shots. It was on July before I burnt my credit card on the Hyperstar. Stars are round, black seemed black to me … yeah, overall it was a big effort, getting all the setup C9+AltAz mount+ Equatorial Wedge + Reducer + Cooled Camera (44kg of setup)
