The Return of the Messier Marathon! Members’ Night, March 17th

March and Early April are one of the most amazing times in the celestial calendar. In the Northern Hemisphere (depending your latitude), on nights from late March through to the first couple of weeks of April, astronomers can view a good rotation of the night sky. If you’re intrepid, from dawn to dusk, there’s the opportunity to see ALL of the objects in Messier’s catalog!

M1 – M110 will be available, but it is a challenge to see them all. But, many amateur astronomers have taken up this challenge – to see all 100, or at least a majority of them, during a 10-11hr window. There IS a real strategy to achieve this goal, but it is doable! It is a real testament to an astronomer’s stamina, astronomical planning, observing, and logging skills to achieve it.

Fast Track 203: Optics and Filters

Fast Track 203: Optics and FiltersWhat is the difference between a 20mm eyepiece and a 25mm eyepiece? What does 60°, 80°, 100° really mean and why is it important? I see two 20mm eyepieces, but one is 1″ vs 2″ – what’s the difference? Why does my object look different on my 6″ vs someone else’s? Or – why is it very challenging to view The Horsehead Nebula, when I know I’m right on it?

Join us for the next Fast Track event which focuses on Optics and Filters! Bring eyepieces and your scopes, and we’ll talk about the differences in eyepieces (and what focal length really affects), understand a field of view, and learn some of the quick calculations so you can understand what optics should work better for your equipment ahead of making these critical purchases.

We will also look at the techniques around selecting filters: what are they, how do they help, what is the composition of our objects, and why do they help immensely for some observing and certainly towards capturing images.

And as always, once we finish the daytime class portion, we’ll set up our telescopes and practice using these techniques or learn how to anticipate and see the differences in combinations.

Terry Phillips has agreed to lead us again, and I’m sure it’ll be awesome!

Please bring your astrokit, along with your log for classroom notes and observing notes. You’ll also want to prepare for cool weather, chairs, snacks. We may view a few things inside the observatory as well.

As always, please sign up so we have enough materials for the night. And yes, it’s a members-only event! Any questions, please contact Member Services team!

Fast Track 201: Astrophotography

Please join us on Nov 19 for the next session of our members-only Fast Track series – this one focuses on Astrophotography!
Update: The session starts at 4:00 pm

David Ault, with Larry Martin, will lead members through some of the key starting (and intermediate) points of capturing light through the photographer’s lens. We’ll start promptly at Eagle Eye Observatory at Canyon of the Eagles at 5pm with some daylight training and discussing, move into set up, break a little, and then prepare for evening viewing and imaging. So signup today!

Observing report for July 30, 2016

Public Star Party, July 30, 2016

Arrived in the early afternoon to do some grounds maintenance with Domingo, Brian V, and Mark. 8 observing table tops were replaced, the walkway work was started, and some 6-month recurring work on the telescope focusers was completed. It was a beautiful summer day, but it sure was hot out there!

Guests started arriving just before sunset, pretty much filling up the parking lot, as the sky turned completely clear. Viewing conditions were about as good as I have ever seen them at EEO, with a cooling breeze throughout the night. There was a very bright Iridium flare just after sunset. Scorpius dominated the Southern sky, and Sagittarius was high in the sky. The Milky Way was bright and clear from horizon to horizon. We got to see 5 planets: Venus, Mercury (great view, it actually set after Venus), Jupiter, Mars, and Saturn. M13 Hercules globular cluster and M57 Ring Nebula where nearly directly overhead, perfect for viewing. The Whirlpool and Pinwheel galaxies in Ursa Major were also unusually bright and clear.
