This is my first attempt at photographing Rho Ophiuchi while on vacation at a dark site. Antares is my favorite star, so I've been excited to grab this since I started AP. Thin clouds were passing the whole night, so I had to prune my session of 91 frames; the orange/yellow blurry corners are cloud smears. I had a telescope pointed at the Iris concurrently but I couldn't figure out why the exposures were so short (when I got home I discovered the camera was set to Av mode bawling.gif). Monsoons decided to crop up early, and only during the week I was there, and this was my only clear night. crazy.gif

 

I was very happy to capture the dark nebula and detail in M4, but then found an extra surprise in the Blue Horsehead Nebula while violently stretching. One day I'll plan another trip to get this constellation again.
