Good enough to bring the telescope out. And, I didn't have to burn a vacation day from work to do it.
After getting the equipment situated, I attached the imager and immediately captured many tens of thousands of frames of Mars for "seeing conditions going south" insurance purposes. I then continued my survey of the sky surrounding Mars -- like I did in last week's post, "Mars' Neighbors."
Mars is still in Capricornus so I thought I'd take a look at the stars that define that constellation's shape. I'm pretty pleased that I did! At least one of Capricornus' stars is a double. These two stars, Algedi Secunda and Algedi Prima, are separated by only a little over 6 minutes. To the unaided eye, they appear as one star!
Algedi Secunda and Algedi Prima
|Diffraction spikes are pretty!|
Just to the right of this double, by about 8 degrees, is another gem of a find!
NGC 6818, The Little Gem Nebula
This is apparently also known as the "Green Mars Nebula," making it entirely fitting to be mentioned in this blog.
|It's a beautiful bluish-green!|
The Milky Way arches completely across my sky when the moon isn't out. It starts in the constellation Sagittarius, which always beckons exploration. With Mars so nearby, the allure is strong . . . Sometimes, I point the telescope at Sagittarius and just slowly move it upwards, seeing whatever happens to come into view. But, not this morning. I stopped at the Lagoon Nebula and admired its pool of pinkish-purple.
M 8, The Lagoon Nebula
Pinkish-purple! To the unassisted eye, the Lagoon Nebula doesn't have any color. It merely appears as a light gray dim pool of light. It was exciting to watch as each successive frame added by SharpCap brought out the color and detail. If you don't have SharpCap, what are you waiting for? Purchase a pro license to support its author. It's only £10 (GBP) for a year of great Electronically Assisted Astronomy (EAA). (Note that I have no affiliation with SharpCap. I'm just a very satisfied user.)
|And dust lanes, too!|
And then, finally, Mars was at its apex around 0424. The seeing conditions had not deteriorated since I made my "insurance" captures a few hours previously.
|Dusty Mars? Please, No!|
Here is what the Virtual Planet Atlas calculates for Mars on June 16th, 2018.
