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)

Helix Nebula

I’m back in Sardegna, my second home …Last time I was there, I caught a glimpse of Laguna Nebula. This time I have the Hyperstar and I really aim for shooting a lot … but I forgot how stubborn this island is.

Laguna Nebula, third try.

Always a special feeling with this nebula. It is currently my first shot with my Hyperstar lens. I started astrophotography with my APN Canon EOS 550D attached to the Schmidt-Cassegrain C9 on this object. When I got the Hyperstar from Starizona, it was a slap in my face getting these details.

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)

Equatorial Wedge

This picture shows two new things I added up. But this post is about the equatorial wedge and my attempt to compensate the earth rotation for my astrophotography shots. You can see the tripod and on top the wedge and the AltAz mount.

Great Orion also named Messier 42

This picture is important to me. That’s my first shot I’m kind of proud of. Messier 42 is a winter nebula but March was a good month to catch it.

Laguna Nebula, first shot

I have a special feeling about this nebula. First, it’s because it was my first shot with my Schmidt-Cassegrain and my APN Canon on September 2021, when I was in Sardegna. The result is what it is, but getting the red spot was a thrilling moment
