Backyard Solar Astronomy in New Jersey

Solar image taken with a Nikon D3x and Questar 3.5″ Telescope fitted with a sun filter (ISO 400, f/16, 1/1000 sec). I didn’t see any sunspots. A good source for solar activity is SpaceWeather.com.

I didn’t have anything from previous years for this day so I went out and took an image of the moon tonight. The image was taken with a D3x and 400 mm AF-S f/2.8 D II with a AF-S TC20EIII teleconverter. ISO 100, 800 mm, 1/200 sec, f/8. Processed using Capture NX2, Photoshop CS5, Focus Magic, converted for web and sRGB using Photoshop CS5. The white balance in the camera was 3030 °K. This probably could be made a bit warmer.

Gone to See Hawaii, Maui Day 3: Sunset over Haleakala Satellite Tracking Station

I left the meeting early to get to the Pu’U’Ula’Ula peak in Haleakala National Park for sunset. When I got to the parking lot I saw this bird, which I later identified as a Chukar. The elevation here is about 10,000 feet, and as the sun went down it got windy and cold fast. The thermometer on my GPS indicated 30°F, and I only had a light windbreaker. I didn’t think to carry cold weather gear for the trip to Hawaii. I did get several great images of the sunset over the nearby Haleakala Air Force Satellite tracking station and observatories.
