Not too long ago, Tucson, Arizona was surrounded by Titan Missile Silos as in this diagramatic postcard. This particular silo is now called "The Titan Missile Museum".

Here is Volcán Maipo, located exactly in the border between Chile and Argentina, in the Andes mountain range, with Laguna Diamante in the background, totally in the Argentinian side of the border.
This picture was taken by my pilot friend César Dariman, when flying from Santiago (Chile) to São Paulo (Brazil), soon after having taken off on 31st January 2020. It was later processed by me.
Very distantly, a beautiful Cumulonimbus cloud with a huge top of Cirrus clouds (the distinctive anvil formation) contrasts with soothing deep blue skies, on the account of the temperature inversion layer immediatly above.

Na imagem, em primeiro plano, o Vulcão Maipo, localizado exatamente na fronteira entre o Chile e a Argentina, na Cordilheira dos Andes, com a Laguna Diamante ao fundo, situada inteiramente no lado argentino.
Esta imagem foi capturada pelo meu amigo piloto de aviação comercial, César Dariman, ao voar de Santiago (Chile) para São Paulo (Brazil), pouco após ter decolado, em 31 de janeiro de 2020. Foi posteriormente processada por mim.
Muito distante, no lado direito, nota-se uma bela nuvem do tipo Cumulonimbus, totalmente desenvolvida, com nuvens cirriformes ao topo, no característico formato de bigorna, contrastando com límpidos e lenitivos céus azuis, por força da camada de inversão térmica logo acima.
This image shows how close Jupiter and Saturn were on 20 December 2020, seen from Maceió-AL, Brazil, at 21:00 UT.
This was the first image where the two planets fit mutually in the Field of View (FOV) of the 12-inch telescope in prime focus with the QHY183C camera. During the two days that preceded the occasion, I had to use a f/6.3 focal reducer in order to accomplish that. And, before that, I had resorted to a 80 mm APO with a 2x Powermate, and, then, a C8 with the f/6.3 focal reducer.
30% out of about 1500 frames were stacked with AS!3 and then post-processed with Photoshop.
I was pleased with the results. And I hope you can enjoy!
This image was achieved with the collaboration of my friend Romualdo Caldas.
The California Zephyr, ready for boarding and Eastward-bound, sits on a track alongside the Union Station in Denver Colorado. With a familiar orange “Union Station, Travel by Train” sign on both the railyard and public entrance sides advertising its primary purpose, the great hall, which was built in 1914, still functions as ticketing and check-in location for Amtrak. The site is now owned by RTD Denver, and it underwent a complete renovation in 2012 (about five years after this photo was made) as a transit oriented center for buses, light rail, and passenger trains. The remodeled Union Station complex also hosts a hotel, restaurants, and retailers serving both travelers and the general public.
