CTB1 - Finally …

I've been patient ... I have this supernova remnant in my mind for a very long time. I knew I needed to step up my game and skills to get it, especially for the blue-green part of it (Oxygen 3 gases). I also knew that despite my fast setup, I would have needed multiple nights to catch the best of it. Here's CTB1.

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)
