200 mm f/5.6 2 sec exposure at ISO 800.

Observation Log:
I drove from Murrieta to Lake Elsinore to the observation point on Grape Street. After offering the Maghrib (sunset) prayers at 7:03 PM I setup the camera and tried some test shots. At 7:23 PM I saw the crescent moon appear as the sky got slightly darker. Any prayers we make upon sighting a new moon are surely accepted, so I immediately raised my hands and made a few special prayers. I then started to look for the comet using my Orion WorldView 10x50 binoculars. At 7:27 PM I sighted the comet, Alhamdulillah. I could also make out the tail as you see in the pictures above! By 7:30 PM I was able to spot it barely with the naked eye, too.

I took a total of 46 pictures, bracketing around the optimum exposure, as the camera indicated. I also tried different zoom settings and some vertical shots. Finally at 7:53 PM the comet followed the moon and set behind the mountains.

The two pictures above are the best of the 46 shots I took. No processing was done except for reducing the image size and adding the text, and jpeg compressing of 75%.  Unfortunately, blogger seems to compress it more, thus reducing the quality even more.

A couple was also observing at the other end of the parking lot. Closer to me was another guy just hanging out in his truck. I walked up to him and showed him the comet with my binoculars. He was thrilled and very pleased. Another guy walked up from the road with his dog and asked "what kind of resolution do you need to take a picture of that?" as he started to play with his little iPhone. Resolution??? What you need is aperture, and the ability to control the exposure time.

Day 2: I drove with my family to a turnout on N. Main Divide off of Ortega Highway (Hwy 74). I was able to observe the comet with my binoculars briefly before it disappeared behind the mountain. This location was not very good. Then we quickly got into the car and drove to the other side of Ortega Highway on the next turnout on S Main Divide. From there we were able to see the comet for about twenty minutes or so. The last picture above was one of the better ones from the ninety pictures that I took from S Main Divide.

Subhan Allah. And Alhamdulillah these pictures turned out to be rather good.
