In September 2019, I attended a presentation at our local New Jersey library by Mike Greene, a NASA Ambassador. The 50th anniversary of Apollo 11 was the featured story as part of a very complete presentation of the entire Apollo program. I had no idea that 1,000 NASA Ambassador volunteers were passionately giving these free history lectures around the country.
Of course, I couldn’t resist telling Mike about my connection to the program, and he enthusiastically accepted my request to contribute to his future presentations at libraries in northern New Jersey. After Mike delivers his presentation, he introduces me by explaining my relationship with the Apollo program. Continue reading “Al with NASA Solar System Ambassador Mike Greene!”
Apollo 11 made a splashdown in the Pacific Ocean 50-years ago today after an 8-day mission. Thus ended the mission that made the historic first manned landing on the Moon with the Lunar Module named Eagle.
Over the past 8-days, we’ve been reminded of the audacious journey, made 50-years ago, to set foot on Earth’s nearest neighbor: the Moon. A constant in our sky, this orb has been gazed upon by countless generations of people who thought it beyond reach. The Apollo moon landings changed all that and left a mark on our human psych. The phrase “Moonshot project,” for a large-scale, ground-breaking endeavor has been in the public lexicon ever since. Images looking back at Earth from the Apollo missions put our planet in a new perspective and prompted American poet Archibald MacLeish to write: “To see the earth as it truly is, small and blue and beautiful in that eternal silence where it floats, is to see ourselves as riders on the earth together, brothers on that bright loveliness in the eternal cold — brothers who know now they are truly brothers.”
We recently received an interesting letter from Stephen Pizzo, discussing his solar imaging work with Tele Vue Powermate™ amplifiers. Most of the time (90%), he uses our 4x Powermate™ on a Hydrogen-α scope — either a LS152THA (900mm focal length) or LS230THa (1,600mm focal length). This extends the effective focal length of these dedicated solar scopes to 3,600mm or 6,400mm for breathtaking, close-up images of the activity on the Sun’s chromosphere. The choice of scope depends on the seeing conditions. If conditions won’t support the 4x, Stephen employs our 2x Powermate™ with the LS230THa for an effective focal length of 3,200mm. Stephen also notes that he normally uses 3″ to 4″ of extension between the 4x Powermate™ and the imager to get another 0.5x of magnification. The imager itself is very unique: a RED Dragon Epic monochrome 18-megapixel camera — a camera usually associated with the world of professional digital cinema.
He shared the images created with the bigger scope and 4x Powermate™ with us. As you can see below, they are spectacular!
