M31 – Andromeda Galaxy

Subject: M31 - Andromeda Galaxy
Telescope: Celestron CPC 800 with f/6.3 reducer
Camera: Canon Rebel T1i
Technique: 1 light (30 seconds at 6400 ISO)
Prime focus. Noise reduction in Photoshop

Tonight was a spur of the moment night for astrophotography. Sarah and I were outside enjoying the Perseids when I realized it was the clearest night I’d had in months. So, I set up the telescope in the dark and took some quick shots. This was one of them.

This was one of the brightest (deep sky) objects in the sky so I was able to get away with a single shot (i.e., no stacking), albeit a bit noisy at that high iso. There are a lot of things wrong with this picture such as the focus, star trailing, noise, and vignetting. I attribute all of these things to not having time to prepare...

M26 – Open Cluster

Subject: M26
Telescope: Celestron CPC 800
Camera: Canon Rebel T1i
Technique: 1 lights (30 seconds at 6400 ISO).
Prime focus.

Tonight was a spur of the moment night for astrophotography. Sarah and I were outside enjoying the Perseids when I realized it was the clearest night I’d had in months. So, I set up the telescope in the dark and took some quick shots. This was one of them.

As with my previous cluster shots, this was bright enough to require only 1 photo. This particular cluster doesn’t have a name, but is very noticeable if you are star hopping in the galactic core (which is very enjoyable). This, along with the Omega Nebula were the main reasons I decided I couldn’t skip tonight’s clear sky opportunity.

As with my previous shot of the Andromeda Galaxy, here are a lot of things wrong with this picture such as the focus, star trailing, noise, and vignetting. These are mostly due to the fact that I basically just whipped out my telescope and started shooting without any preparation. I expect to get much better shots of the Omega Nebula in the future.

Galactic Center

Subject: Milky Way Galaxy
Technique: 30 seconds at 800 iso, f/3.5. 18mm. Post-processed in Photoshop

Tonight was a little cloudy, but I managed to get this shot when the clouds parted. As usual, I had to fight with light pollution in the post-processing. Doing so is much more difficult with large subjects such as the galactic core.
