Your 2021 Sky Event Planner

The Jupiter and Saturn “Great Conjunction” was well-publicized and well-imaged. Even though the closest approach between the planets was Monday, they’re still in the vicinity and worth a look tonight! This gallery contains some of the best images of the event we found on-line, acquired with Tele Vue products.
Dear Tele Vue Aficionado,
Thank you for your continued enthusiasm for our products. Weāre sorry for some product delays due to an unexpected increase in demand during this pandemic time.
Hereās an announcement Iām making today thatās unique in my lifetime, leaving me conflicted between happy and sad:
Weāve sold out of our limited edition special production run of the Apollo 11 eyepiece celebrating the 50th anniversary of the first Moon landing.
Yes, Iām sad they are gone, but happy to have spread more joy among our astronomical community. Little did I know in the 1960s that my design for the LEM Simulator optics, showing a 110° star field to the astronauts would change my life, inspiring me to eventually share wide-field views with fellow amateur astronomers by founding Tele Vue Optics, Inc.
Iād appreciate your taking a few minutes to see my PowerPoint presentation, I Thank My Lucky Stars on the Tele Vue blogĀ to share my life path with you.
Stay well,
Al Nagler
Our readers followed the story of the development, arrival, packaging, and distribution of the Apollo 11mm eyepiece on our blog. See the following links:

According to a recent Solar Activity Update by the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center, “Solar activity picked up at the end of November into early December, 2020, as several sunspot groups emerged or rotated onto the visible disk”.Ā The update continues: “Solar activity is anticipated to slowly increase over the upcoming years towards the predicted solar maximum peak around July, 2025.” This is great news for observers of our nearest star! At times this year, there had been month-long sunspot “droughts” with no or few sunspots on the solar disk.
The return of Sun as a target of interest has led to a sudden uptick in Solar image postings to social media these past few weeks.Ā
Is it just us or did it seem that 2020 was a longer than usual year? Yet while both the year and big Mars Opposition are waning, we can still look forward to some astronomical sights and surprises in the “20/20” sky. We list them in this week’s blog.
Even though we’re past the point of closest approach and opposition, Mars continues to loom large in the sky and is higher each night at the same time. In the northern hemisphere, the nights are coming sooner and lasting longer. Until mid-November, Mars will appear bigger than at any opposition until 2033!
You can use the excellent Mars Mapper 2020-2021Ā web app (mobile version) on the British Astronomical Association website to identify features on the planet when you observe or image it.
If you’d like to try your hand at imaging the planet, study the next sections carefully as they contain image processing tips from top Martian imagers on the Internet.
We’ve reached the peak of the current Mars observing season with the planet closest to Earth:62-million km or 38.5-million miles on October 6/7th. At -2.5 magnitude and 22.6″ in diameter, Mars is aĀ conspicuous, intense orange target in the sky that is brighter than any star, except our Sun and is only outshone by Venus and the Moon in the nighttime sky. When it reaches opposition next week, on October 13th, it will still be 22.4″ in diameter and a tad brighter at -2.6 magnitude.Ā It will remain greater than 20″ in diameter for the whole month. So, weather permitting, put an eyepiece in the scope this month and show it to all your friends!
The public will likely learn from the media that the Mars Opposition is a “one-night” event, on October 13th,Ā when the planet rises at sunset and is brighter and larger in appearance than usual. However, amateur astronomers know that the 2020 Mars Opposition is more like a “season,” where the planet grows in size each night over months, stays near peak size for a while, and then slowly fades away over the weeks. This gives us an observation window much longer than a single night!Ā Ā
