The above portrait of the Horsehead and Flame nebulae is stunning. Created in Hydrogen-alpha light, this monochrome image is filled with wispy tendrils, puffy molecular clouds, dark lanes, and glowing gas. It really brings out the interplay of shockwaves and ionizing radiation at work in this region of the much larger Orion Molecular Cloud Complex.
You can compare this image with the color one below of the same region. The red hues are dramatic, but we lose a sense of the “sculpting” that is taking place in the gas and dust.
The Horsehead (Barnard 33) and Flame Nebulae (NGC 2024) are separated by the bright blue supergiant star Alnitak (center-left in the above image), the easternmost star in the “Belt” of constellation Orion. Like a giant neon sign, the “Flame”, below Alnitak in the image, is “lit up” by ultraviolet light from the star. The flame-like appearance is enhanced by dark “branches” of light-absorbing gas in the nebula. As for the Horsehead, its appearance is due to the three-star system Sigma Orionis “above” the “horse” (bright star along a line through the horse’s neck and head). It causes hydrogen gas to glow behind a dark concentration of dust that has the distinctive appearance of a horse’s head.
Tele Vue’s product quality, consistency, and reliability are well known in amateur astronomy circles. So, it shouldn’t come as a surprise that our top-tier optical performance also attracts the interest of professional astronomers looking for “off-the-shelf” solutions for their experimental needs. Tele Vue also provides researchers with the in-depth technical analysis necessary to determine if product integration is feasible or if custom solutions are required.
In this multi-part blog post we’ll explore some of the published science using our standard gear and take a look at a future science mission that called for a custom designed Tele Vue lens. Note that all the studies in the series, except the last one in this part, were produced with products bought off-the-shelf, same as you would receive from Tele Vue.
Tele Vue telescopes spread out along the center-line of the Monday, August 21, 2017 North American Eclipse. Our employees and friends report on their eclipse experiences. Our second report is from Al Nagler’s totality trip to Columbia, SC.
A year ago, Judi (wife and Tele Vue co-founder 40 years ago) planned this eclipse trip, our 4th. I decided, agreeing with Neil deGrasse Tyson’s recommendation, to concentrate on the unforgettable visual experience of totality. Boy was he right!
We reserved rooms at the Hilton Embassy in Columbia, SC and drove there starting on Saturn-Day (pardon my passion for changing the name) August 19th, arriving on Sunday afternoon to meet-up with our good friends Gail and Matt Cowit to share the experience. I immediately found a good parking spot with my car trunk facing a large open area and nearby trees for shade benefit :-).
What I like about star parties is meeting and speaking to all the fine people that travel long distances for great observing experiences. Sometimes the conversations continue after the event. This is an excerpt from a note I received from Bob Danko, of Warren Ohio, soon after returning from the Cherry Springs Star Party this June.
