Excellent, Floyd. I also like the little background galaxies.

Death Valley Gains Dark Sky Status

Posted By Fred Lusk

I saw that. It's great news. I remember reading online a few years ago that one of the astronomy clubs in the Las Vegas area wes using the Mesquite Springs Campground for an annual star party. That campground is in the black part of the light pollution map, while the southern part of the park is in the gray due to the Las Vegas light dome.

I have a slight chance to pull off a 3- or 4-day camping trip to DVNP in April, but it would be around the full moon.

Comet Pan-STARRS and the Moon Setting

Posted By Fred Lusk

That's a beautiful image. Where in the Sierras were you?

I've been stuck in Fresno all week and haven't had the chance to venture out to a better site to see the comet. I saw it a couple times this week, including the same night you took this photo, but only through a gap in my neighborhood trees and only through the valley haze.

My wife and I hosted a star party last night for about 20 people, but the comet was behind clouds the whole time and we chased holes overhead. We got some solar viewing in and the Moon, Jupiter, Orion, etc put on a nice show when they were in the clear. I may have to go out again tonight.

Yosemite Reflections and Moonbow

Posted By Fred Lusk

Most of Yosemite's waterfalls have rainbows at some time during the day, but a few even have moonbows when conditions are right. Dr. Don Olson, Texas State University, San Marcos, covered this in a Sky & Telescope article in 2007. Here are some links:

This photo was shot with an Olympus E-5 and 50 mm f/2.0 macro. ISO = 800, t = 10 s, f/ = 2.8. It was a full moon last night (like I need to remind Astromarters), which is what illuminated the landscape.

Yosemite Reflections and Moonbow

Posted By Fred Lusk

This photo was taken at about 9 p.m. The moonbow isn't much here, but I picked up enough stars to outline a few constellations. I annotated this photo and the next two for our club meeting last Saturday.

I need Help with astrophotography!!

Posted By Fred Lusk

Rob…

I suggest starting with the Moon. It's bigger and brighter and easier to get focused properly with a DSLR.

There are some books on the subject, though I don't own any of them. smile You may want to check out "Digital SLR Astrophotography" by Michael A. Covington. I have his older "Astrophotography for the Amateur" (it's mostly film-based) and it's quite good.

Good luck.
